Qmail redirect mail to another one and keep local Mailbox copy with .qmail file – Easy Set up email forwarding Qmail

Qmail redirect mail box to another one with .Qmail file dolphin artistic logo

QMail (Considered to be the most secure Mail server out there whose modified version is running on Google – Gmail.com and Mail Yahoo! and Yandex EMail (SMTP) servers, nowadays has been highly neglected and considered obsolete thus most people prefer to use postfix SMTP or EXIM but still if you happen to be running a number of qmail old rack Mail servers (running a bunch of Email addresses and Virtual Domains straight on the filesystem – very handy by the way for administration much better than when you have a Qmail Mail server configured to store its Mailboxes within MySQL / PostgreSQL or other Database server – because simple vpopmail configured to play nice with Qmail and store all user emails directly on Filesystem (though considered more insecure the email correspondence can be easily red, if the server is hacked it is much better managable for a small and mid-sized mailserver) or have inherited them from another sys admin and you wonder how to redirect a single Mailbox:

(under domain lets say domain's email  my-server1.com should forward to to SMTP domain my-server-whatever2.com (e.g. your-email-username@server-whatever1.com is supposed to forward to your-email-username2@server-whatever2.com).
To achieve it create new file called .qmail

Under the Qmail or VirtualDomain location for example:

/var/qmail/mailnames/myserver1.com/username/.qmail

 

e.g
 

root@qmail-server:~# vim /var/qmail/mailnames/myserver1.com/your-email-username/.qmail
&your-email-username@server-whatever1.com

your-email-username@example1.com
/home/vpopmail/domains/server-whatever2.com/your-email-username/Maildir/


!!! NOTE N.B. !!! the last slash / after Maildir (…Maildir/) is important to be there otherwise mail will not get delivered
That's all now send a test email, just to make sure redirection works properly, assuming the .qmail file is created by root, by default the file permissions will be with privileges root:root.

Note
 

That shouldn't be a problem at all. That's all now enjoy emails being dropped out to the second mail 🙂

 

Email Linux alternative text console clients to Thunderbird, fetchmail, Mutt, fetchmail + Alpine how to

Saturday, November 4th, 2017

linux-email-alternatives-for-text-console-email-fetching-gathering-alternative-to-thunderbird-and-evolution-howto

As a GNU / Linux user you might end up searching for the best email client to satisfy your needs, for those who used so far Outlook Express on M$ Windows first switch to GNU / Linux the most likely one to choose is either Mozilla Thunderbird or GNOME's Evolution default Mail Clientbut what more text / console programs are there that will allow you to easily check email via POP3 and IMAP on Linux?

 

1. Install Fetchmail and use to collect and copy your emails from remote server to your local machine
 

 SSL enabled POP3, APOP, IMAP mail gatherer/forwarder
 fetchmail is a free, full-featured, robust, and well-documented remote mail
 retrieval and forwarding utility intended to be used over on-demand TCP/IP
 links (such as SLIP or PPP connections).  It retrieves mail from remote mail
 servers and forwards it to your local (client) machine's delivery system, so
 it can then be read by normal mail user agents such as mutt, elm, pine,
 (x)emacs/gnus, or mailx.  The fetchmailconf package includes an interactive
 GUI configurator suitable for end-users.

To install it, issue:
 

apt-get install –yes fetchmail procmail


To configure fetchmail to gather your mail from your POP3 / IMAP mailbox, create below
.fetchmailrc configuratoin and modify according to your account

 

# vim .fetchmailrc

 

#### .fetchmailrc
 set daemon 600
 set logfile fetchmail.log

 poll the_mail_server_hostname proto POP3

  user "Remote_Username" pass "PASSWORD=" is "local_username" preconnect "date >> fetchmail.log"
 #ssl
  fetchall
  #no keep
  no rewrite
  mda "/usr/bin/procmail -f %F -d %T";


Here is also few words on each of the .fetchmailrc config options

set daemon 600 The fetchmail binary with run in the background in daemon mod and fetch mail from the server every 600 seconds or 10 minutes.

set logfile fetchmail.log This will set the directory and file name of the fetchmail user log file. Eveytime fetchmail recieves an email, checks the pop3 server or errors out you will find an entry here.

poll the_isp_mail_server proto POP3 This line tells fetchmail what mail server to contact, in theis case "the_isp_mail_server" and to use the "POP3" protocol.

user "remote_user_name" pass "PASSWORD" is "local_username" preconnect "date >> fetchmail.log The user directive tells fetchmail what the name of the user on the remote mail server is for example "remote_user_name". The pass directive is simply the password you will use for the remote user on the mail server. The "is" directive is optional. It tells fetchmail to deliver mail to a diferent user name if the user on the remote mail server and the local machine are different. For example, I may be using the name "joe.doe" on the mail server, but my local user name is "jdoe". I would use a line like user "joe.doe" pass "PASSWORD" is "jdoe". The preconnect command simply adds the current time and date to the fetchmail log file every time fetchmail checks for new mail.

ssl The "ssl" directive tells fetchmail to use encryption when connecting to the pop3 mail server. Fetchmail will use port 995 instead of port 110 for un-encypted mail communication. In order to use ssl the remote mail server must be able to use ssl. Comment out this directive if you do _not_ use pop3s.

fetchall Fetchall just means to fetch all of the mail on the mail server no matter what the "read" flag is. It is possibly to read mail through many different processes. If you use another mail client from another location, for example you could have read you mail and kept it ont he server, but marked it with the "read" flag. At this point if you did _not_ use the "fetchall" flag then only mail marked as new would be downloaded.

no keep Once the mail is downloded from the mail server fetchmail is to tell the server to remove it from the server. You may choose to comment this option out if you want to leave all mail on the server.

no rewrite Do not rewrite headers. When fetchmail recieves the mail you do not want any of the headers mangled in any way. This directive tells fetchmail to leave the headers alone.

mda "/usr/bin/procmail -f %F -d %T"; The mda is your "mail delivery agent. Procmail is the program that fetchmail will hand the mail off to once it is downloaded. The argument "-f %F" logs who the mail if from and "-d %T" turns on explicit delivery mode, delivery will be to the local user recipient.

For configuring multiple mailboxes email to be gathered to local machine through fetchmail add to above configuration, some more config similar to this:

 poll mail.example.com protocol pop3:
       username "admin" password "your-plain-text-password" is "username" here;
       username "what-ever-user-name" password "Just-another-pass#" is "foreman" here;

  poll mail.example.org protocol pop3 with option sslproto '':
       user "whatever-user1" password "its-my-pass" mda "/usr/bin/procmail -d %T":   user "whatever-user1" password "its-my-pass" mda "/usr/bin/procmail -d %T

 


Because as you can see fetchmail keeps password in plaintext it is a best security practice to set some good file permissions on .fetchmailrc just to make sure some other local user on the same Linux / Unix machine will not be able to read your plaintext password, to do so issue below command.
 

chmod 600 ~/.fetchmailrc

 

For the purpose of logging as we have it into the config you will also need to create new blank file fetchmail.log
 

touch fetchmail.log


Once fetchmail all your emails you can use mail command to view your messages or further configure alpine or mutt to read the downloaded messages.

 

2. Use Alpine text based email client to check your downloaded email with fetchmail
 

Alpine is Text-based email client, friendly for novices but powerful
 Alpine is an upgrade of the well-known PINE email client.  Its name derives
 from the use of the Apache License and its ties to PINE.

In other words what Alpine is it is a rewritten and improved version of the good old PINE Unix email client (for those who remember it).

To give alpine a try on Debian / Ubuntu install it with:

 

apt-get install –yes alpine pilot

 

Mutt-text-console-linux-email-client

 


3. Use MuTT advanced and much more colorful text email client to view your emailbox

mutt-text-email-client-logo-dog

 Mutt is a sophisticated text-based Mail User Agent. Some highlights:
 .
  * MIME support (including RFC1522 encoding/decoding of 8-bit message
    headers and UTF-8 support).
  * PGP/MIME support (RFC 2015).
  * Advanced IMAP client supporting SSL encryption and SASL authentication.
  * POP3 support.
  * ESMTP support.
  * Message threading (both strict and non-strict).
  * Keybindings are configurable, default keybindings are much like ELM;
    Mush and PINE-like ones are provided as examples.
  * Handles MMDF, MH and Maildir in addition to regular mbox format.
  * Messages may be (indefinitely) postponed.
  * Colour support.
  * Highly configurable through easy but powerful rc file.

 

To install MuTT:

 

linux:~# apt-get install –yes mutt

Configuring mutt if you don't have priorly set-up with fetchmail to collect your remote e-mails, you might want to try out .mutt's email fetch features to do so you will need a .muttrc configuration like that:
 

# Automatically log in to this mailbox at startup
set spoolfile="imaps://User_Name:Your-Secret-Password@mail.example.com/"
# Define the = shortcut, and the entry point for the folder browser (c?)
set folder="imaps://mail.example.com/"
set record="=Sent"
set postponed="=Drafts"

You might also omit placing the password inside .muttrc configuration as storing the password in plaintext might be a big security hole if someone is able to read it at certain point, but the downside of that is you'll be asked by mutt to fill in your email password on every login which at a point becomes pretty annoying.
 

If you face problems with inability of mutt to connect to remote mail server due to TLS problems, you can also try to play with below configurations:
 

# activate TLS if available on the server
 set ssl_starttls=yes
 # always use SSL when connecting to a server
 set ssl_force_tls=yes
 # Don't wait to enter mailbox manually
 unset imap_passive        
 # Automatically poll subscribed mailboxes for new mail (new in 1.5.11)
 set imap_check_subscribed
 # Reduce polling frequency to a sane level
 set mail_check=60
 # And poll the current mailbox more often (not needed with IDLE in post 1.5.11)
 set timeout=10
 # keep a cache of headers for faster loading (1.5.9+?)
 set header_cache=~/.hcache
 # Display download progress every 5K
 set net_inc=5
 

 

Once you have the emails downloaded with fetchmail for your mailbox mutt should be showing your email stuff like in below screenshot
 

linux:~$ mutt

 

 

Mutt-text-console-linux-email-client

Of course a very handy thing to have is w3m-img text browser that displays images as it might be able to open your pictures attached to email if you're on a physical console tty.

I'll be curious to hear, if you know of better and easier solutions to check mail in console, so if you know such please drop a comment explaining how you check your mail text.

 

Why don’t you use Window Maker GNU Step to improve your computer interaction performance

Why-dont-you-use-Window-Maker-graphical-environment-for-your-GNU_Linux-FreeBSD-desktop

If you're pissed off too already of GNOME 3 Unity / GNOME 3 Flashback and KDE Plasma  as I am you perhaps are looking for something more light weigth but you're not okay with default Debian Cinnanom GUI environment or you don't feel confortable for system administration jobs and programming with XFCE then perhaps you would like to give a try to something more old school but build with good design in Mind.

Those who are fans of the evil genius Steve Jobs (as Richard Stallman use to call him), definitely Remember NeXT company and the revolutionary Graphic Environment they tried to develop NeXT Step then you'll be happy to hear about GNUStep  which historically was called AfterStep and is a Free Software remake of NextStep graphical environment for Free and Open Source operating systems (FOSS) such as GNU / Linux and FreeBSD / OpenBSD / NetBSD etc.

Amanda_the_panda_mascot_of_window_maker-graphical-environment-system

Amanda the Panda is the mascot of Window Maker. She was designed by Agnieszka Czajkowska.

The good thing about Window Maker and the complete bunch of desktop environment GNUStep is it much lighter and less complex than the more and more becoming bloated modern Free Software graphical environments, it definitely easifies the way the user interacts with basic browsing with Firefox / Opera, terminal code writting or command system administration and basic chat functionalities such as with Gajim or Pidgin and basic email writting operatins be it with some text email client such as Mutt or with Thunderbird. Its great also to reduce the overall load the Operating System puts on your brain so you can have more time to invest in more useful stuff like programming.

windows-maker-increase-performance-of-work-with-your-computer-howto-wmaker-screenshot

After all simplicity in Operating System is a key for an increased productivity with your computer.
Besides that stability of Window Maker is much better when compared to GNOME and GNOME 2 fork MATE graphical environment which nowadays in my opinion is becoming even more buggy than it used to be some years ago.

Below is how Window Makers site describes Window Maker:

"Window Maker is an X11 window manager originally designed to provide integration support for the GNUstep Desktop Environment. In every way possible, it reproduces the elegant look and feel of the NEXTSTEP user interface. It is fast, feature rich, easy to configure, and easy to use. It is also free software, with contributions being made by programmers from around the world.

Window Maker has a stable user interface since many years and comes with a powerful GUI configuration editor called WPrefs, which removes the need to edit text-based config files by hand. It supports running dockapps which make everyday tasks such as monitoring system performance and battery usage, mounting devices or connecting to the internet very easy. Please see the features section for more specifics on what Window Maker can do, and how it compares with other popular window managers."

Window Maker is bundled with a number of useful applications which gives ability to put Dock applets easily for easily intearcive desktop update of current Weather Report, Monitoring Network Traffic, TV Player (video4linux), laptop battery info dock, CD player and Volume control management app, text editor, pdf viewer, integrated Mail application, Calculator, RSS Reader, GNUStep games and much useful things to customize from the desktop resembling many of the basic features any other graphical environment such as GNOME / KDE Provides.

The User Interface (UI) of Window Maker is highly configurable with an integrated WMaker tool called

WPrefs

Why-dont-you-use-Wmaker-for-better-desktop-performance-Windowmaker_colour_preferences

All generated settings from WPrefs (Window Maker Prefernces) GUI tool are to be stored in a plaintext file:
 

~/GNUstep/Defaults/WMRootMenu

All Wmaker configurations are stored inside ~/GNUstep/ (Your user home GNUStep), so if you're to become its user sooner or later you will have to get acquired to it.

Wmaker is very minimalist and the performance is killing so Window Maker is perhaps the number one choice Graphical Environment to use on Old Computers with Linux and BSD.

Well yes it is true Window Maker is not a spoon for every mouth, those who want to have more confortable desktop environment better look out at other options as Window Maker is Unix / Linux graphical environment that fits better hackers, computer developers and system administrators.

Anyhow if you have some old family member that has to use an old computer architecture and the person is only to use mainly just browser to check email, youtube and basic surfing then Wmaker will be a great choice as it will consume little CPU and Memory much less than the heavy and computer resources sucking GNOME and KDE.

I've historically used Wmaker also with its teminal emulator rxvt (VT102 terminal emulator for the X Windows System) which is a kinda of improved version of xterm (the default terminal program bundled with Xorg server), but for those who are already used to Gnome Terminal nice tabs perhaps that would be not the terminal of choice.

rxvt was build to match well the look and feel of AfterStep and consequently Wmaker, its scrollbar was aiming to very much resemble NeXTStep style scrollbar

Most "custom" shortcuts are used to launch specific applications. To add your own keyboard shortcut for an application, go to the "Applications Menu Definition" panel in the Preferences app.  Select the application item in the menu for which you want to create a shortcut, then use the "capture" button to capture the keystrokes you want to assign to that item.  In the screenshot, I've assigned Mod1 + W to open Firefox.

Above  screenshot shows how to map the Run Application keyboard bind to behave like GNOME Run application ALT + F2

Customizing background of Window Maker

Because WMaker is so simple made and targetting more of a developer audience for use it doesn't have a special graphical interaface to set a Background if you like so, but instead you need to use a wmsetbg command to do so:
 

wmsetbg -s -u filename.jpg

 

WMSetBG command stands for WindowMaker Set Background


If you're too lazy to install and start configuring wmaker, there is a Window Maker LiveCD, you can run Window Maker through LiveCD in Virtual Machine such as VirtualBox to get feeling what you're about to get if you install and start using Wmaker on your Computer.

Well at first with Window Maker you might feel confused and quickly irritating missing the already established way to work with your computer, but that's just for a starter sooner you will realize, that for using a limited number of applications for work wmaker, makes you much more efficient. Moreover using your computer with Wmaker can rewire your brain circuits to think a little bit different.

Once you switched to Window Maker you will likely want to have a graphical option to connect to Wireless Networks especially if you're using Wmaker on a notebook it is convenient to not always manually do scan for networks with

If you're into a huge company like IBM (no it doesn't stand for I Blame You butInternational Business Machines ) or Hewlett Packard – where using Microsoft Windows mailing is almost mandatory and you have to write tons of mails daily, you will certainly need to do plenty of screenshots.
Screenshotting in MS Windows is a very trivial thing, you press Prt + Scr (Print Screen Button), open Microsoft Paint and paste (CTRL+V) the file into it then Save the file as a lets say JPEG extension. However if you have to do that regularly, each time to create a screenshot you will have to loose a minute or two. Also it is quite annoying to open Paint and
Outlook version 2010 has a very useful feature Take screenshot from any existing opened Window on Windows host.
To make screenshot directly from Outlook mail client. Click the Write new mail Button

New E-mail -> Insert (tab) -> (click Screenshot)
Depending on your ribbon menu setup, this might be a tiny icon—specifically, a little camera icon with a dotted rectangle.
You will be offered to choose along all opened Windows, for the Window from which you would like to have screenshot, choose one and enjoy
If you don't see a window you want to insert, make sure the program isn't minimized to the taskbar.
Alternatively, if you want just a portion of the screen, click on the Screen Clipping button at the bottom of the Screenshot dropdown. This will bring up a crosshair cursor for you to drag around the area of the screen you want to select.
Your selection should then be inserted into your emailscreenshot ready to share with your mates.

Fix random reboots of ZTE Blade 3 Android and other chineese smartphones – Fix battery strange discharge after reboot

Monday, August 25th, 2014

fix-solve-random-mobile-reboots-on-chineese-Android-mobile-phones-Android_greenman_logo
I'm owning ZTE Blade 3 chineese brand mobile phone. I thought there is not a big deal to buy chineese mobile phone as it saves money but the good old saying: "The Cheap always is more expensive" came true to proof the old wisdom.

The phone runs some Android port of version 4.0.4 and generally it runs well for a couple of days, but after the increase of application the battery started discharging too quickly, I have to charge almost daily … also occasionally since I have turned synchronization of mobile phone numbers with Google  from settings the ZTE Andorid phone started to randomly loose its contacts (after which I had to restore with proprietary application Dr. Fone). After a while I realized there is another fix, sometimes Contacts restore was also possible through using free application Contacts Sync Fix, but most of the times the only thing that could resolve the contacts is to dig for lost phonebook contacts with Dr. Fone …. Eventually I realized the Lost PhoneBook Contacts issue can be resolved by itself on a random principle so the missing phones issue sometimes solved by itself just by switching off complete the phone for some time and switching it on again after 12 hours?! Recently I found another alternative way to restore sudden (deleted) disappered phone numbers by:

Settings -> Profiles and Synchronization -> (Go to configured gmail account settings) -> Settings of Profile

Then

(Frequency of syncrhonization, messaging etc.) -> (click over the email address) -> Frequency of email check (every 4 hours) 

Set the every 4 hours settings to Never and then after a minute or 2 (interval), set back the Never (opt) to every 4 hours

Since some time I started facing another more severe problem – random phone reboots after which the battery often kept at a critically low charged. The batter often fall to 40% or 50% charge from 99% / 100% charge, and after some time of talking over the phone the battery fall down to as low as 18% and in a short random time it fall to 9%, then after a reboot it uppered the charge to 35% or 45% and the oddities continued. My first guess was it could be the battery being broken, some colleagues at work advised me to completely discharge the battery so the phone couldn't boot and then try to charge it with Battery Doctor free Android Application. Battery Doctor has a special 3 stage charging:

battery-doctor-android-revolutionary-battery-3-stage-charging-or-recovering-deat-dried-out-batteries-calibrating-broken-android-phone-battery-application

1. Bulk Charge

The primary purpose of a battery charger is to recharge a battery. This first stage is typically where the highest voltage and amperage the charger is rated for will actually be used. The level of charge that can be applied without overheating the battery is known as the battery's natural absorption rate. For a typical 12 volt AGM battery, the charging voltage going into a battery will reach 14.6-14.8 volts.

Where first 80% of the battery are charged with a rapid electricity influx to battery once 80% of battery charge is reached charging is moved to the so Absorption Battery Charge

2. Absorption Charge

Smart chargers will detect voltage and resistance from the battery prior to charging. After reading the battery the charger determines which stage to properly charge at. Once the battery has reached 80%* state of charge, the charger will enter the absorption stage. At this point most chargers will maintain a steady voltage, while the amperage declines. The lower current going into the battery safely brings up the charge on the battery without overheating it. This charge phase takes much longer time to charge.
Then comes the final charging state Float Charge

3. Float Charge

Some chargers enter float mode as early as 85% state of charge but others begin closer to 95%. Either way, the float stage brings the battery all the way through and maintains the 100% state of charge. The voltage will taper down and maintain at a steady 13.2-13.4 volts, which is the maximum voltage a 12 volt battery can hold. This charging is also known as "trickle charging". Float Charging battery electricity influx is so small that you can leave the phone to charge in this mode for days (if you like).

But guess what, after I tried to completely discharge the battery, it discharged to a state where it auto rebooted just before Android boots and reboots again and again, after nothing happened for about 2 hours of leaving the phone to automatically rebooted I decided to try the Battery Doctor 3 stage charging without having my battery completely dried out. The 3 Stage Charging is also known as Android Battery Calibration process and as I heard it helped fix many people's battery which for some reason got their Android battery in a broken state without physically substituting it.

Unfortunately In my case using Battery Doctor didn't help … so after spending time to read on some forum threads finally found this one. There many Bulgarians complained for buying ZTE Blade III and Huawei variations from the 3 major stream bulgarian mobile phone operatorsM-Tel, Vivacom and Globul and shortly after experiencing the strange random chineese smart phone reboots.  Some suggested that the Android Kernel is causing the issues or the firmware and suggested Phone Software Reset, however as I red most people that tried to solve it that way reported this doesn't solve it. Many People said to have shipped the phone as it was in a warranty back to services and phones were given back often with flushed firmware and in a little while the problem re-occured, some reported of another strange fix – a tiny sticky thing which kept the battery more stable?!! 🙂

zte-blade-3-and-huawei-and-other-android-chineese-phone-random-reboot-problem-fix-picture

Yes I know it looks kinda of insane … as this little holder could be any piece of paper and many reported to have fix the random battery charge drop down by sticking a tiny piece of paper between the battery and mobile shell I try it myself and GUESS WHAT?? IT WORKED !!! :)))

zteblade3_and-other-android-based-mobile-phone-brands-resolve-restart-fix-solution-screenshot

This is pretty much the Bulgarian and Russian primitive way to fix things but it works 🙂 I was exceedingly happy as I already have spend plenty of money for this mobile and I really was unwilling to buy another phone and it was out of warranty. I guess the whole issues started after I have occasionally dropped my phone on a couple of times on the ground and some little piece of plastic holding the battery eroded or whatever … Anyways the PAPER WAY WORKS! Cheers and hope this saves someone else out there from having to spend on new mobile!

Hooray !!! Thanks goes to the Lord Jesus Christ for Everything, for helping me solve it ! 🙂

Stop contact form spam emails in Joomla, Disable “E-mail a copy of this message to your own address.” in Joomla

Friday, April 11th, 2014

email-copy-of-this-message-to-your-own-address_Contact_email_form
If you happen to have installed Joomla based website and setup a contact form and everything worked fine until recently but suddenly your server starts mysteriously acting as a spam relay – even though email server is perfectly secured against spam.
You probably have some issue with a website email contact form hacked or some vulnerability which allowed hackers to upload spammer php script.

I have a website based on Joomla and just until recently everything was okay until I noticed there are tons of spam flying out from my Qmail mail server (which is configured to check spam with Spamassassin has Bayesian Filtering, Distributed Checksum Claring House, Python Razor and plenty of custom anti-spam rules.

It was just yesterday I ended into that situation, then after evaluating all the hosted website, I've realized Spam issues are caused by an Old Joomla Website Contact form!

There were two issues in the form

in the contact form you have the field with a tick:

1. Well Known Joomla Form Vulnerability
Currently all Joomla (including 1.5.22 and 1.6 versions) are vulnerable to a serious spam relay problem as described in the official Joomla site.

There is a quick dirty workaround fix to contact form vulnerability –  disable a Joomla Comonent in ../joomla/components/com_mailto/

To disable it I had to:

cd /var/www/joomla/components
mv com_mailto com_mailtoNOT_USED

Above solution was described under a post resolve joomla spam relay earlier by Anatoliy Dimitrov (after checking closely the website it happened he is a colleague at HP 🙂 )

2. Second issue causing high amount of spam sent over the email server
was: "E-mail a copy of this message to your own address." contact form tick, which was practically enabling any Spammer with a list to inect emails and spam via the form sending copies to any email out on the internet!

You would definitely want to disable  "E-mail a copy of this message to your own address."
I wonder why ever any Joomla developer came up with this "spam form"?? 

joomla-disable-email-copy-of-this-message-to-your-own-address

Here is the solution to this:

1. Login to Joomla Admin with admin account
2. Goto Components -> Contacts -> Contacts
3. Click on the relevant Contact form
4. Under Contact Parameters go to Email Parameters
5. Change field E-mail Copy from Show to Hide and click Apply button

And Hooray the E-mail a copy of this message to your own address will be gone from contact form! 🙂

I've seen already plenty of problematic hacked servers and scripts before with Joomla in my last job in International University College – where joomla was heavy used, but I never experienced Joomla Security issues myself 'till know, in future I'm planning to never ever use joomla. Though it is an easy CMS system to setup a website its quite complicated to learn the menus – I remember when creating the problematic website it took me days until I properly setup all the menus and find all joomla components … besides these there is no easy way to migrate between different versions major releases in Joomla like in Wordperss, I guess this Mail Security Issue absolutely convinced me to quit using that piece of crap in future.

In mean Time another very serious Apache security flaw leaked on the Internet just few days ago – The OpenSSL Hearbleed Bug. Thanksfully I'm not running SSL anywhere on my website but many systems are affecting making most of your SSL communication with your Internet banking, E-mail etc. in danger. If you're running Apache with SSL make sure you test it for this vulnerability. Here is description of Heartbleed SSL Critical Vulnerability.

heartbleed_ssl_remote_vulnerability_logo

"The Heartbleed Bug is a serious vulnerability in the popular OpenSSL cryptographic software library. This weakness allows stealing the information protected, under normal conditions, by the SSL/TLS encryption used to secure the Internet. SSL/TLS provides communication security and privacy over the Internet for applications such as web, email, instant messaging (IM) and some virtual private networks (VPNs).

The Heartbleed bug allows anyone on the Internet to read the memory of the systems protected by the vulnerable versions of the OpenSSL software. This compromises the secret keys used to identify the service providers and to encrypt the traffic, the names and passwords of the users and the actual content. This allows attackers to eavesdrop on communications, steal data directly from the services and users and to impersonate services and users."

How to change Outlook Signature – modify and delete Microsoft Outlook email signatures

Monday, February 17th, 2014

I'm using Mozilla Thunderbird over the last 5 years in my life. Just now in my new job place in Hewlett Packard, in order to have well functional mail (with exchange server) – I started using Microsoft Outlook.
Logically a little while after I started my work I have to update my Outlook E-mail signature to reflect my contact details (job position title, email, stand-alone / mobile phone, office address etc.). As of moment of writting I'm using Microsoft Outlook 14.0.6123.5001 (32 bit) part of Microsoft Office Professional Plus 2010.

Its a kind of irony that I had to use Microsoft products after all these years trying my best to avoid using Microsoft technologies but heh, this is life … Though this article will be a bit trivial I decided to blog it because already I had to change email signature for a 3rd time over the last 3 months and every now and then after a month time I tend to forget how I did it last time.

Here is how I changed Email Signature in Outlook:

1. Click on "New-Email" (located below File menu)

2. Click on "Insert" (menu tab)

3. Click on "Signature"

microsoft-outlook-pop3-mail-client-change-signature-screenshot

4. Click on "New" button

As you see Outlook is written in very intelligent manner 🙂
It is possible to have more than one signature and change them every now and then (I guess that's made for Schizophrenic people who like changing their signature a couple of times a day accepting different personalities 🙂 🙂 🙂
For already existing signatures just edit the old one – click on Edit Signature

microsoft-outlook-exchange-how-to-change-email-signature
http://www.clarion.edu/273437/
 

  • Rename Signatures:

        Perform steps 1-4 in ('Create Signatures') except click "Rename button instead of 'New' and begin typing new name.

  • Delete Signatures:

        Perform steps 1-4 in ('Create Signatures') except click 'Delete" button instead of 'New'.

  • Modify Signatures:

        Highlight signature name you wish to modify under

  1. "Select Signature to Edit" then modify signature.

  2. Click "Save" button to save any signature changes made.

How to quickly check unread Gmail emails on GNU / Linux – one liner script

Monday, April 2nd, 2012

I've hit an interesting article explaining how to check unread gmail email messages in Linux terminal. The original article is here

Being able to read your latest gmail emails in terminal/console is great thing, especially for console geeks like me.
Here is the one liner script:

curl -u GMAIL-USERNAME@gmail.com:SECRET-PASSWORD \
--silent "https://mail.google.com/mail/feed/atom" | tr -d '\n' \
| awk -F '' '{for (i=2; i<=NF; i++) {print $i}}' \
| sed -n "s/

As you see this one liner uses curl to fetch the information from mail.google.com's atom feed and then uses awk and sed to parse the returned content and make it suitable for display.

If you want to use the script every now and then on a Linux server or your Linux desktop you can download the above code in a script file -quick_gmail_new_mail_check.sh here

Here is a screenshot of script's returned output:

Quick Gmail New Mail Check bash script screenshot

A good use of a modified version of the script is in conjunction with a 15 minutes cron job to launch for new gmail mails and launch your favourite desktop mail client.
This method is useful if you don't want a constant hanging Thunderbird or Evolution, pop3 / imap client on your system to just take up memory or dangle down the window list.
I've done a little modification to the script to simply, launch a predefined email reader program, if gmail atom feed returns new unread mails are available, check or download my check_gmail_unread_mail.sh here
Bear in mind, on occasions of errors with incorrect username or password, the script will not return any errors. The script is missing a properer error handling.Therefore, before you use the script make sure:

gmail_username='YOUR-USERNAME';
gmail_password='YOUR-PASSWORD';

are 100% correct.

To launch the script on 15 minutes cronjob, put it somewhere and place a cron in (non-root) user:

# crontab -u root -e
...
*/15 * * * * /path/to/check_gmail_unread_mail.sh

Once you read your new emails in lets say Thunderbird, close it and on the next delivered unread gmail mails, your mail client will pop up by itself again. Once the mail client is closed the script execution will be terminated.
Consised that if you get too frequently gmail emails, using the script might be annoying as every 15 minutes your mail client will be re-opened.

If you use any of the shell scripts, make sure there are well secured (make it owned only by you). The gmail username and pass are in plain text, so someone can steal your password, very easily. For a one user Linux desktops systems as my case, security is not such a big concern, putting my user only readable script permissions (e.g. chmod 0700)is enough.

How to reduce spam in PHPBB based internet forum on Debian GNU / Linux

phpbb reduce spam bot registrations on Debian Linux tiny script

I had to install two PHPBB based internet forums, some long time ago. Since long time passed and I haven't checked what's happening with them I just noticed. They start filling up spam threads. The phpbb installations are done using the standard shipped deb packages in Debian Linux Lenny.

After checking online, I found one smart solution to . The idea is very simple most spam bots are written in a way that they don't have a properly set timezone. Therefore the quickest way to get rid of spam bots which try to auto register and put spam content inside the a forum category or post is to add a simple if condition in php to check the browser set timezone:

The file to add the php if condition is ucp_register.phpThe phpbb package install places default phpbb path on Debian is /usr/share/phpbb3/ and hence the file I had to modify is located in:

/usr/share/phpbb3/www/includes/ucp/ucp_register.php

To make the TZ check one needs to modify ../www/includes/ucp/ucp_register.php and look for php array definition:

$data = array(
'username' => utf8_normalize_nfc(request_var('username', '', true)),
'new_password' => request_var('new_password', '', true),
'password_confirm' => request_var('password_confirm', '', true),
'email' => strtolower(request_var('email', '')),
'email_confirm' => strtolower(request_var('email_confirm', '')),
'confirm_code' => request_var('confirm_code', ''),
'lang' => basename(request_var('lang', $user->lang_name)),
'tz' => request_var('tz', (float) $timezone),
);

Right after this chunk of code add the if condition code which is like so:

if ($data['tz'] == '-12.00')
{
die('Die, bot! Die.');
}

From now onwards, any attempt for new user registration with an incorrect timezone of -12.00 will be immediately stopped while the forum spammer bot will be offered an empty page 🙂

Another good practice is to disable Birthday Listing from phpbb Admin Control panel (ACP). Go to menus:

ACP -> General -> Board Settings -> Enable Birthday listing: (No)

Enable birthday listing phpbb forum screenshot

I like disabling birthday listing, as when it is enabled and you have some spammer registrations, which even though didn't succeeded to contaminate your forum content has specified a birthday and therefore there profiles gets popping up each different day on the main page of the forum.
This will not eradicate all spammer bots, but at least will significantly decrease spammer bot registrations.

How to resolve (fix) WordPress wp-cron.php errors like “POST /wp-cron.php?doing_wp_cron HTTP/1.0″ 404” / What is wp-cron.php and what it does

Monday, March 12th, 2012

fix wordpress wp-cron.php 404 HTTP error, what is wp-cron.php schedule logo

One of the WordPress websites hosted on our dedicated server produces all the time a wp-cron.php 404 error messages like:

xxx.xxx.xxx.xxx - - [15/Apr/2010:06:32:12 -0600] "POST /wp-cron.php?doing_wp_cron HTTP/1.0

I did not know until recently, whatwp-cron.php does, so I checked in google and red a bit. Many of the places, I've red are aa bit unclear and doesn't give good exlanation on what exactly wp-cron.php does. I wrote this post in hope it will shed some more light on wp-config.php and how this major 404 issue is solved..
So

what is wp-cron.php doing?

 

  • wp-cron.php is acting like a cron scheduler for WordPress.
  • wp-cron.php is a wp file that controls routine actions for particular WordPress install.
  • Updates the data in SQL database on every, request, every day or every hour etc. – (depending on how it's set up.).
  • wp-cron.php executes automatically by default after EVERY PAGE LOAD!
  • Checks all pending comments for spam with Akismet (if akismet or anti-spam plugin alike is installed)
  • Sends all scheduled emails (e.g. sent a commentor email when someone comments on his comment functionality, sent newsletter subscribed persons emails etc.)
  • Post online scheduled articles for a day and time of particular day

Suppose you're writting a new post and you want to take advantage of WordPress functionality to schedule a post to appear Online at specific time:

What is wordpress wp-cron.php, Scheduling wordpress post screenshot

The Publish Immediately, field execution is being issued on the scheduled time thanks to the wp-cron.php periodic invocation.

Another example for wp-cron.php operation is in handling flushing of WP old HTML Caches generated by some wordpress caching plugin like W3 Total Cache
wp-cron.php takes care for dozens of other stuff silently in the background. That's why many wordpress plugins are depending heavily on wp-cron.php proper periodic execution. Therefore if something is wrong with wp-config.php, this makes wordpress based blog or website partially working or not working at all.
 

Our company wp-cron.php errors case

In our case the:
212.235.185.131 – – [15/Apr/2010:06:32:12 -0600] "POST /wp-cron.php?doing_wp_cron HTTP/1.0" 404
is occuring in Apache access.log (after each unique vistor request to wordpress!.), this is cause wp-cron.php is invoked on each new site visitor site request.
This puts a "vain load" on the Apache Server, attempting constatly to invoke the script … always returning not found 404 err.

As a consequence, the WP website experiences "weird" problems all the time. An illustration of a problem caused by the impoper wp-cron.php execution is when we are adding new plugins to WP.

Lets say a new wordpress extension is download, installed and enabled in order to add new useful functioanlity to the site.

Most of the time this new plugin would be malfunctioning if for example it is prepared to add some kind of new html form or change something on some or all the wordpress HTML generated pages.
This troubles are result of wp-config.php's inability to update settings in wp SQL database, after each new user request to our site.
So the newly added plugin website functionality is not showing up at all, until WP cache directory is manually deleted with rm -rf /var/www/blog/wp-content/cache/

I don't know how thi whole wp-config.php mess occured, however my guess is whoever installed this wordpress has messed something in the install procedure.

Anyways, as I researched thoroughfully, I red many people complaining of having experienced same wp-config.php 404 errs. As I red, most of the people troubles were caused by their shared hosting prohibiting the wp-cron.php execution.
It appears many shared hostings providers choose, to disable the wordpress default wp-cron.php execution. The reason is probably the script puts heavy load on shared hosting servers and makes troubles with server overloads.

Anyhow, since our company server is adedicated server I can tell for sure in our case wordpress had no restrictions for how and when wp-cron.php is invoked.
I've seen also some posts online claiming, the wp-cron.php issues are caused of improper localhost records in /etc/hosts, after a thorough examination I did not found any hosts problems:

hipo@debian:~$ grep -i 127.0.0.1 /etc/hosts
127.0.0.1 localhost.localdomain localhost

You see from below paste, our server, /etc/hosts has perfectly correct 127.0.0.1 records.

Changing default way wp-cron.php is executed

As I've learned it is generally a good idea for WordPress based websites which contain tens of thousands of visitors, to alter the default way wp-cron.php is handled. Doing so will achieve some efficiency and improve server hardware utilization.
Invoking the script, after each visitor request can put a heavy "useless" burden on the server CPU. In most wordpress based websites, the script did not need to make frequent changes in the DB, as new comments in posts did not happen often. In most wordpress installs out there, big changes in the wordpress are not common.

Therefore, a good frequency to exec wp-cron.php, for wordpress blogs getting only a couple of user comments per hour is, half an hour cron routine.

To disable automatic invocation of wp-cron.php, after each visitor request open /var/www/blog/wp-config.php and nearby the line 30 or 40, put:

define('DISABLE_WP_CRON', true);

An important note to make here is that it makes sense the position in wp-config.php, where define('DISABLE_WP_CRON', true); is placed. If for instance you put it at the end of file or near the end of the file, this setting will not take affect.
With that said be sure to put the variable define, somewhere along the file initial defines or it will not work.

Next, with Apache non-root privileged user lets say www-data, httpd, www depending on the Linux distribution or BSD Unix type add a php CLI line to invoke wp-cron.php every half an hour:

linux:~# crontab -u www-data -e

0,30 * * * * cd /var/www/blog; /usr/bin/php /var/www/blog/wp-cron.php 2>&1 >/dev/null

To assure, the php CLI (Command Language Interface) interpreter is capable of properly interpreting the wp-cron.php, check wp-cron.php for syntax errors with cmd:

linux:~# php -l /var/www/blog/wp-cron.php
No syntax errors detected in /var/www/blog/wp-cron.php

That's all, 404 wp-cron.php error messages will not appear anymore in access.log! 🙂

Just for those who can find the root of the /wp-cron.php?doing_wp_cron HTTP/1.0" 404 and fix the issue in some other way (I'll be glad to know how?), there is also another external way to invoke wp-cron.php with a request directly to the webserver with short cron invocation via wget or lynx text browser.

– Here is how to call wp-cron.php every half an hour with lynxPut inside any non-privileged user, something like:
01,30 * * * * /usr/bin/lynx -dump "http://www.your-domain-url.com/wp-cron.php?doing_wp_cron" 2>&1 >/dev/null

– Call wp-cron.php every 30 mins with wget:

01,30 * * * * /usr/bin/wget -q "http://www.your-domain-url.com/wp-cron.php?doing_wp_cron"

Invoke the wp-cron.php less frequently, saves the server from processing the wp-cron.php thousands of useless times.

Altering the way wp-cron.php works should be seen immediately as the reduced server load should drop a bit.
Consider you might need to play with the script exec frequency until you get, best fit cron timing. For my company case there are only up to 3 new article posted a week, hence too high frequence of wp-cron.php invocations is useless.

With blog where new posts occur once a day a script schedule frequency of 6 up to 12 hours should be ok.
