How to disable spammer domain in QMAIL mail server with badmailto variable

Thursday, July 12th, 2012

I've recently noticed one of the qmail SMTP servers I adminster had plenty of logged spammer emails originating from destined to reache some random looking like emails (probably unexisting) again to *

The spam that is tried by the spammer is probably a bounce spam, since it seems there is no web-form or anything wrong with the qmail server that might be causing the spam troubles.
As a result some of the emails from the well configured qmail (holding SPF checks), having a correct existing MX, PTR record and even having configured Domain Keys (DKIM) started being marked, whether emails are sent to * legit emails.

To deal with the shits, since we don't have any Taiwanese (tw) clients, I dediced to completely prohibit any emails destined to be sent via the mail server to * This is done via /var/qmail/control/badmailto qmail control variable;

Here is content of /var/qmail/control/badmailto after banning outgoing emails to;;;

qmail:~# cat /var/qmail/control/badmailto

The first 4 lines are default rules, which are solving a lot of badmailto common sent emails. Thanks God after a qmail restart:

qmail:~# qmailct restart

Checking in /var/log/qmail-sent/current, there are no more outgoing * destined emails. Problem solved …

IE PassView – View stored Microsoft Internet Explorer passwords program

Thursday, January 5th, 2012

While checking a friend of mine's blog, I've seen a reference to a Windows program capable of revealing stored website passwords.
Check stored internet explorer passwords in plaintext with IE PassView

IE PassView is a small password management utility that reveals the passwords stored by Internet Explorer Web browser, and allows you to delete passwords that you don't need anymore. It supports all versions of Internet Explorer, from version 4.0 and up to 9.0.
Ie PassView is quite a good one for crackers, who would like to steal some lame poor Windows IE user facebook,gmail, yahoo etc. passwords 😉 here is a link to IE Passview's download page

How to build website sitemap (sitemap.xml) in Joomla

Monday, December 20th, 2010

A joomla installation I’m managing needed to have created a sitemap.xml

From a SEO perspective sitemap.xml and sitemap.xml.gz are absolutely necessary for a website to bewell indexed in google.

After some investigation I’ve found out a perfect program that makes generation of sitemap.xml in joomla a piece of cake.

All necessary to be done for the sitemap.xml to be created comes to download and install of JCrawler

What makes JCrawler even better is that it’s open source program.

To install Jcrawler go in the joomla administrator panel:

Extensiosn -> Install/Uninstall

You will see the Install from URL on the bottom, there place the link to the installation archive, for instance you can place the link of the downloaded copy of I’ve mirrored on ,by placing it on

The installation will be done in a few seconds and you will hopefully be greated with a Installation Success message.

Last thing to do in order to have the sitemap.xml in your joomla based website generated is to navigate to:

Components -> JCrawler

There a screen will appear where you can customize certain things related to the sitemap.xml generation, I myself used the default options and continued straight to the Start button.

Further on a screen will appear asking you to Submit the newly generated sitemap to; Google, MSN,, Moreover and Yahoo , so press the Submit button.
That’s all now your joomla website will be equipped with sitemap.xml, enjoy!

How to add Apache 301 redirect to VirtualHost in Apache

Sunday, September 25th, 2011

I’ve had two domain names which were pointing to the same website content.
As one can read in any SEO guide around this is a really bad practice as search engines things automatically there is a duplicate site content and this has automatically a negative effect on the site pagerank.
To deal with situation where multiple domains are pointing to the same websites its suggested by many SEO specialists that a 301 redirect is created from all the domain websites to a single website domain which will open the actual website.

Making the 301 direct domain from the sample domain to can be done with a virtualhost dfefinition in either httpd.conf or with the respective file containing the domain virtualhost definitions:
Here is the exact VirtualHost code I use to make a 301 redirect.

<VirtualHost *>  ServerAdmin  ServerName
RewriteEngine on RewriteRule ^/(.*)$1 [L,R=301]

After placing the VirtualHost redirect, an apache redirect is required.
Further on when a Gooogle or Yahoo Bot visits the website and does any request to or , they will be redirected with a 301 reuturned code to

This kind of redirect however can have a negative impact on the Apache CPU use (performance), especially if the is high traffic domain. This is because the redirect is done with mod_rewrite.

Therefore it might be better on high traffic domains to create the mod_rewrite redirect by using a vhost like:

<VirtualHost *>
Redirect 301 /

The downside of using the Apache 301 redirect capabilities like in the above example is that any passed domain urls like let’s say would not be 301 redirected to but instead the redirect will be done straight to

Recovering long lost website information (data) with wayback machine

Monday, May 9th, 2011

Wayback machine, see 2 years old website from cache service

I needed a handy way to recover some old data of an expired domain containing a website, with some really imprtant texts.
The domains has expired before one year and it was not renewed for the reason that it’s holder was not aware his website was gone. In the meantime somebody registered this domain as a way to generate ads profit from it the website was receiving about 500 to 1000 visitors per day.
Now I have the task to recover this website permanently lost from the internet data. I was not able to retrieve anything from the old domain name be contained via google cache, yahoo cache, bing etc.
It appears most of the search engines store a cached version of a crawled website for only 34 months. I’ve found also a search engine gigablast which was claimed to store crawled website data for 1 year, but unfortunately gigablast contained not any version of the website I was looking for.Luckily (thanks God) after a bit of head-banging there I found a website that helped me retrieve at least some parts from the old lost website.

The website which helped me is called WayBack Machine

The Wayback Machine , guys keeps website info snapshots of most of the domain names on the internet for a couple of years back, here is how wayback machine website describes its own provided services:

The Internet Archive's Wayback Machine puts the history of the World Wide Web at your fingertips.

Another handy feature wayback machine provides is checking out how certain websites looked like a couple of years before, let’s say you want to go back in the past and see how yahoo’s website looked like 2 years ago.

Just go to and type in yahoo and select a 2 years old website snapshot and enjoy 😉

It’s really funny how ridiculous many websites looked like just few years from now 😉

Automatic blog posts tagging in wordpress blog 3.1 with (auto-tags) / wp plugin to increase Search Engine ranking

Monday, April 4th, 2011

There are plenty of articles, on how to increase search engine ranking in wordpress and I’m sure this article might be not that interesting but still I thought it might be nice to mention about this 3 wordpress plugins Auto-Tags, SEO Slugs and Platinium SEO Pack which will help you increase your traffic.

Let me say a few words for each of the 3 plugins:

1. Auto-tags
Below is the description of the plugin directly taken from the plugin website

This plugin uses the and APIs to find the most relevant keywords
from the content of your post, and then adds them as tags.
New for version 0.2: an options page allows to choose how many tags are
retrieved from each service The tag adding is fully automatic,
so if you're using a plugin like feedwordpress to display RSS feeds
on your blog as posts, everything will get done as the feed
posts are published. No user intervention necessary!

Here are the installation instructions for auto-tags:

debian:~# cd /var/www/blog/wp-content/plugins
debian:/var/www/wp-content/plugins:# wget
100%[================================>] 14,325 45.3K/s in 0.3s

2011-04-04 12:30:17 (45.3 KB/s) – `’ saved [14325/14325]
debian:/var/www/wp-content/plugins:# unzip

In the above example my wordpress installation is in /var/www/blog/ , if your wordpress is installed in another directory location change to the respective directory.

To activate the Plugin go to:

Plugins -> Auto Tags
Press over Activate to activate the plugin.

To configure the Auto-tags plugin navigate to:

Settings -> Auto tags plugin

Auto tags Screen options

Therein you can configure the number of post tags to be retrieved from Yahoo, The settings also allows you to disable certain tags you don’t want to appear in your post tags from the field, Remove those tags (comma separated)

The plugin also has an option called Append tags to the ones that already exist which on my wordpress 3.1 installation doesn’t work

After ending up your desired configuration simply press the Update Options button.

Now each time you type a new post in your wordpress blog, a tags related to the post will automatically be included.
Based on this tags Search engines will easily find content that relates to your blog tags and thus your page indexing will get better.

How to redirect ports to access Gmail, Yahoo, Hotmail etc. via a different port number on Debian Linux

Thursday, September 16th, 2010

The university where I study right now ABS – (Arnhem Business School) does some outbound port filtering.
Therefore I couldn’t access my Gmail email through POP3 neither send my emails via the SMTP protocol.

In other words the port numbers 25, 110, 995 and 143 are filtered by the University System Administrator, or whoeverdid built the University network.
This I found pretty annoying because I’ve noticed the Teachers who work on their Desktops are able to access their email addressesvia a normal POP3 and SMTP protocols .
Of course there is likely a good reason that the university filters the traffic for students accessing internet via their notebooks through the Internal built University wireless network, however as I feel very convenient with checking my mail via Thunderbird (Icedove), it’s really, really irritating to go for a browser each and every time I’d like to check my Gmail.

In that reason an idea come to my mind to get through the SMTP, POP and IMAP protocol access restrictions.
The idea is not something brilliant or something too smart, however it prooved to work so I was quite happy with it.

My idea was to simply use my personal Linux router as a jumping off place to access gmail.

To do so first think I did was to scan my Linux router and check which ports are filtered from Arnhem Business School University firewall and which one are allowed to pass traffic.

After a while I have found out that the ports range from 2010 up to 2050 are freely allowing traffic to pass without any firewall restrictions.
Thus my next logical step I took was to configure my Linux router to pass by all incoming traffic on ports 2050 and 2060 to Gmail servers for POP3 email access and the other one responsible for sending emails via the SMTP

In order to fulfill my desired task I first experimented a bit with some iptables nat PREROUTING redirect to destination rules.

However after many tries without success I finally decided to abandom this approach and try with another one.

I’ve remembered that some time ago I’ve used a tiny Linux software called rinetd that makes the port forwardking, redirections a piece of cake

RINETD is really straight forward to install and use on Debian Linux. To make the actual port redirects first you will have to install rinetd

1. Install rinetd

debian-desktop:~# apt-get install rinetd

2. Configure rinetd by editting /etc/rinetd.conf to make the redirects to gmail or any other pop3 mail server host

Open up the /etc/rinetd.conf with your favourite text editor and for a gmail redirect place the lines: 2010 995 2050 25

In the above configuration directives the first IP address should be changed and adjusted with your actual Linux router external IP address.
The second option 2010 is the port number to accept connections from your host to be redirected to the IP , the last argument is the port number to where you desire to redirect 995.
In the above example I’ve used the IP which actually a gmail server IP address I have obtained through resolving and

In order to conduct the resolve I issued the commands:

3. Resolve and to find out their actual IP addresses, which you will have to use in your port redirect

hipo@debian-desktop:~$ host is an alias for has address
hipo@debian-desktop:~$ host is an alias for has address

All left to be done to have the port redirections active is to run up the rinetd service, to do so issue:

debian-desktop:~# /etc/init.d/rinetd start

That’s all, now go to your Thunderbird, Outlook or any POP3 email client of choice and just change the mail server hosts and ports with your Linux router IP address and ports where you just binded the redirect.Of course the Linux router IP could also be used, if you don’t have a hostname associated with it.

Nanoblogger Yahoo Search Field Plugin ( download / install and how to properly escape code in nanoblogger

Saturday, March 13th, 2010

Since some time I’m trying to setup Yahooo Search Field on my nanoblogger without success. I also have difficulties every now and then with escaping source code whenever I decide to drop it in my nanoblogger. Knowing that the official nanoblogger page has the yahoo search next to the google search enabled up and running and considering the fact I couldn’t find any tutorial or instructions online both on nanoblogger’s official webpage as well as to the rest of the searchable internet, I decided to mail Nanoblogger’s author to ask him if he could help me setting up this Yahoo Search Field Plugin as well as ask him what I can do to have a proper code escaping without breaking the blog. I explained that currently I tried a bunch of things without success etc. Below you’ll find my correspondence with Kevin Wood (Nanoblogger’s Author):

Hi Georgi,
Attached is my plugin. Just drop it in your plugins directory
and add $NB_Yahoo to your main_index.htm template. In order to work, it
expects that you have BLOG_FEED_URL set in blog.conf.

You should use the plugin to post escaped HTML code. When
editing your entry you can add markdown to the FORMAT field. Oh, the
markdown plugin requires that you have Markdown installed on your
system and you may have to tweak MARKDOWN_CMD and MARKDOWN_OPTS in your
blog.conf before it will work. Good luck!



Now here is the nanoblogger yahoo search plugin that Kevin sent me.
After putting it in my nanoblogger plugins directory and enabling BLOG_FEED_URL, now all works like a charm.
