Fix Squirrelmail UTF-8 and windows-1251 Bulgarian encoding problem

Monday, September 8th, 2014

squirrelmail_webmail_for_nuts_fix_bulgarian_reply_encoding_problem-howto
I'm using Squirrelmail (with OutLook skin theme) as a webmail client for my home running Qmail mail server and few other squirrelmail plugins, generally I'm quite happy with Squirrelmail as it perfectly serves me as a web IMAP client the only issue I have is when I'm replying to messages which are written Cyrillic UTF-8 or Cyrillic windows cp-1251 encoding (Bulgarian letters) – I guess Russians which are using squirrelmail with KOI-8R encoding also probably face some similar mail encoding issues. That's pretty annoying because the person message which I'm Replying to gets scrapped and old content becomes unreadable so old correspondence gets broken, because the encoding in which the message is replied is in non-utf-8 encoding ISO-8859, you see example of what I mean in below screenshot:

Fix_solve_Squirrelmail_UTF-8_and_windows-1251_Bulgarian_Russian_encoding_problem_screenshot

So here is how to fix that:
Solution is to convert the Bulgarian translation from windows-1251 to UTF-8 in squirremail.po:
 

find . -iname squirrelmail.po
./themes/squirreloutlook-1.0.3/locale/pt_BR/LC_MESSAGES/squirrelmail.po

cd themes/squirreloutlook-1.0.3/locale/pt_BR/LC_MESSAGES/
iconv -f CP1251 -t UTF-8 squirrelmail.po > squirrelmail.utf-8.po
sed 's/cp1251/UTF-8/' squirrelmail.utf-8.po > squirrelmail.po
rm squirrelmail.utf-8.po
msgfmt -o squirrelmail.mo squirrelmail.po
cd ../../../../../


For Squirrelmail version 1.4

find . -iname i18n.php
./functions/i18n.php
./themes/squirreloutlook-1.0.3/functions/i18n.php

vim ./themes/squirreloutlook-1.0.3/functions/i18n.php
vim functions/i18n.php


Paste below, the commented section about Bulgarian Language (//) (below configuration):

 

$languages[‘bg_BG’][‘NAME’] = 'Bulgarian';
$languages[‘bg_BG’][‘CHARSET’] = 'utf-8';
$languages[‘bg_BG’][‘LOCALE’] = 'bg_BG.UTF-8';
$languages[‘bg’][‘ALIAS’] = 'bg_BG';

 

 


For Squirrelmail version 1.5


locale/bg_BG/setup.php
 

Finally to make new Squirrelmail configuration affective restart Apache Webserver

 

/etc/init.d/apache2 restart


Fixing issues with broken (Russian) cyrillic KOI8-R encoding in reply mail in squirrelmail should be analogical.

 

 

 

Install postfix on Debian Wheezy Linux / Postfix mail server with Dovecot and MySQL user storage on Debian Wheezy 7 Linux

Monday, August 5th, 2013

postfix Debian GNU Linux logo picture install and configure postfix with dovecot on Wheezy debian 7 Linux

I have recently installed Postfix on a server following WorkAround.org ISPMail Tutorial on Debian Wheezy Linux 7. Officially as you can see on their website there is no official guide still for Debian Wheezy yet. Therefore my only option was to follow ISPMail tutorial using Postfix 2.7 (Debian Squeeze).

It was quite a struggle to adapt tutorial for Squeeze deb to Wheezy and it took me an  overall time of about of week (each day spending few hours trying to make various components of tutorial) work. But finally I managed to install it. This is how this article got born in hope that in future it will help others have a decent Postfix install on Wheezy.. 

For those unfamiliar with Workaround.org's ISPMail Postfix Tutorial it is pretty much standard step-by-step installation guide for dummies similar to QmailRocks.org or Thibs QmailRocks Updated Installation Guide.

In Other words Workaround.org  is probably the best Postfix full featured install tutorial currently online as of time of writting this post. Workaround.org is great for people who want to run full featured; 

Postfix SMTP configured to support;

 

  • Postfix to support Mail Virtual Domains (store E-mails in MySQL database)
  • Dovecot Secure IMAP / IMAPS / POP3 / POP3s server to offer Pop3 and Imap remote access
  • Support Properly Generated SSL Certificates for POP3s and IMAPs
  • Anti Spam – SMTPD restrictions, SPF,  RBL,  Greylisting
  • Install web frontend to support Web E-mail Domaim / Accounts easy administrations for users stored in MySQL db
  • Amavisd-New (to protect Mail server from Spam)
  • Postfix WebMail frontend with Roundcube or Squirrelmail

Here is the big picture as it gives good idea on how all above components correspond to each other:

how postfix dovecot amavis clamav and spamassassin work postfix the bigpicture

So here we go:
 

1. Install Postfix necessary  debian packages


a) Install Postfix / MySQL / phpmyadmin and Postfix support for MySQL mail storage deb packs

 

apt-get update

apt-get upgrade

apt-get install –yes ssh
apt-get install –yes postfix postfix-mysql
apt-get –purge remove 'exim4*'
apt-get install –yes mysql-client mysql-server dovecot-common dovecot-imapd dovecot-pop3d postfix libsasl2-2 libsasl2-modules libsasl2-modules-sql sasl2-bin libpam-mysql openssl telnet mailutils
apt-get install –yes mysql-server phpmyadmin

 

b) Install deb packages for Dovecot and Imap Support as well as Roundcube and / or Squirrelmail for Webmail support

 

squirrelmail
apt-get install –yes dovecot-pop3d dovecot-imapd dovecot-lmtpd

c) Install packages deb packages for Anti-spam greylisting (tumgreyspf)
 

 

apt-get install –yes tumgreyspf

2. Create necessary MySQL database structures


Next step is toconnect to MySQL as root via MySQL CLI or PhpMyadmin and  CREATE new user "mailuser" and new database "mailserver", then create basic structure for "mailserver" database – i.e. sql tables ("virtual_domains", virtual_users", virtual_aliases")
These user and database is used laters by Dovecot server  to connect and  fetch emails from MySQL on user request via POP3 or IMAP. I've taken all the SQL requests and from Workaround.org's site and placed them in one SQL file:
create-postfix-mysql-user-database.sql.

Below is mysql cli query to import it. If you prefer more user friendliness do it via PhpMyAdmin with a copy / paste from file or with PhpMyAdmin import

 

 

 wget -q https://www.pc-freak.net/files/postfix/create-postfix-mysql-user-database.sql
mysql -u root -p < create-postfix-mysql-user-database.sql

Link to create-postfix-mysql-user-database.sql is here
 

3. Setting up Dovecot required users and directories

Next its necessary configure some users and create directories where Dovecot will store its configuration files. Dovecot requires to create its custom files for each existing users in MySQL database. Therefore whenever user receives or sends e-mail or is simply created Dovecot also creates a user directory structure in /var/vmail/, for exmpl.:
 

 

# ls -al /var/vmail/mail-domain.org/test/mail/
total 20
drwx—— 4 vmail vmail 4096 jul 29 09:15 .
drwx—— 3 vmail vmail 4096 jul 29 07:20 ..
drwx—— 3 vmail vmail 4096 jul 29 09:15 .imap
drwx—— 2 vmail vmail 4096 jul 29 09:15 INBOX
-rw——- 1 vmail vmail   24 jul 29 09:15 .subscriptions

The functions of Dovecot server again are:

  • Get emails from Postfix (MySQL database) and save them to disk
  • Allow mail users to fetch emails using POP3 or IMAP protocol with Outlook / Thunderbird whatever pop3 client

    groupadd -g 5000 vmail
    useradd -g vmail -u 5000 vmail -d /var/vmail -m
    chown -R vmail:vmail /var/vmail
    chmod u+w /var/vmail
    chgrp vmail /etc/dovecot/dovecot.conf
    chmod g+r /etc/dovecot/dovecot.conf
    chown root:root /etc/dovecot/dovecot-sql.conf
    chmod go= /etc/dovecot/dovecot-sql.conf

 

4. Create self-signed SSL certificate for Postfix mail and Dovecot pop3 server

 

 

openssl req -new -x509 -days 3650 -nodes -out /etc/ssl/certs/dovecot.pem -keyout /etc/ssl/private/dovecot.pem
chmod o= /etc/ssl/private/dovecot.pem
/etc/init.d/dovecot restart
openssl req -new -x509 -days 3650 -nodes -out /etc/ssl/certs/postfix.pem -keyout /etc/ssl/private/postfix.pem
chmod o= /etc/ssl/private/postfix.pem

 

5. Configuring Amavis (Anti Virus frontend) with Clamav AV

To reduce viruses it is a must nowadays to install Antivirus in Qmail I used qmail-scanner (perl script) frontend to Clamav Antivirus to check for Viruses and some messed up e-mails. In Postfix just like in Sendmail, tool that does the same is amavisd-new.  There are some configuration files to do, but as its time consuming to do changes one by one I prefer moving old /etc/amavis/ to /etc/amavis-bak/ and download and untar archive with already set  proper configs
 

 

apt-get install –yes amavisd-new
useradd clamav -g amavis
mv /etc/amavis /etc/amavis-old
cd /etc/
wget https://www.pc-freak.net/files/postfix/
amavis-config-debian-wheezy-7.tar.gz
tar -zxvvf amavis-config-debian-wheezy-7.tar.gz

…..
/etc/init.d/amavis start
Starting amavisd: amavisd-new.

Amavisd is meant to communicate in two port numbers with Postfix. Postfix passes Input in one (10024) and Output – Scanned File Status in (10025). Thus for normal amavis operation this two ports has to be showing as listening on localhost, e.g.:
 

 

netstat -nap | grep -E '10024|10025'
tcp        0      0 127.0.0.1:10024         0.0.0.0:*               LISTEN      13957/amavisd-new (
tcp        0      0 127.0.0.1:10025         0.0.0.0:*               LISTEN      9007/master     

 

6. Placing Dovecot working (properly configured) config files for Debian Wheezy

On Workaround.org there are plenty of configurations to copy paste inside files and how it is explained is a bit complicated thus played a lot mainly with /etc/postfix/master.cf and /etc/postfix/main.cf configurations until I finally had a working version of (SMTP) configured not to be an open relay and receive / sent email OK …
Here are configurations that worked for me:
 

 

mv /etc/postfix /etc/postfix-old
cd /etc/
wget -q https://www.pc-freak.net/files/postfix/postfix-configs-debian-wheezy.tar.gz
tar -zxvvf postfix-configs-debian-wheezy.tar.gz
… …..

[ ok ] Stopping Postfix Mail Transport Agent: postfix.

[ ok ] Starting Postfix Mail Transport Agent: postfix.

 

To download my good postfixs-debian-wheezy.tar.gz look here

Afterwards only setting you have to change in /etc/postfix/main.cf is:
 

 

myhostname = example-mail.org

to your Fully Qualified Domain Name (FQDN), lets say www.pc-freak.net
 

myhostname = www.pc-freak.net

I find it also useful to remove from SMTP after connect banner reporting that Postfix is running on Debian in main.cf change:
 

smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)

 to

smtpd_banner = $myhostname ESMTP $mail_name

 

7. Placing Dovecot working config files in /etc/

Configuring Dovecot is not an easy task in Debian Linux Squeeze and Lenny, on Postfix ISPMail guide there is a special tutorial for each as there is none yet for Debian Wheezy. It took me long to figure it out how to translate from old config settings for Wheezy's Dovecot 2.1.7-7. Configuration files places has changed for some clarity in Dovecot 2.1.7-7. So many of the Workaround.rog's Squeeze Tutorial suggested changes in /etc/dovecot/dovecot.conf are to be made in files under /etc/dovecot/conf.d

Therefore quickest way to have working Dovecot is to move default config dir /etc/dovecot to /etc/dovecot-old and place tuned configs:
 

cd /etc/
wget -q https://www.pc-freak.net/files/postfix/dovecot-configs-debian-wheezy.tar.gz
tar -zxvvf dovecot-configs-debian-wheezy.tar.gz

….

chown -R vmail:dovecot /etc/dovecot
/etc/init.d/dovecot restart

[ ok ] Restarting IMAP/POP3 mail server: dovecot.

8.Install Web Interface User / Domain edit Mail Frontend – Mail Admin Tool – Matv1.1

There are 4 web mail admin interfaces suggested by ISPMail tutorial:

 

 

  • Matv.1.1 – Mail Admin Tool
  • ISPWebadmin
  • Mailadm
  • VEA

I tried with ISPWebadmin and VEA, but only one that worked for me is MATv1.1. Actually I liked a lot Mail Admin tool it is simple and does support; create new mail domains, create new users in domains and add user aliases.

Mail admin tool login screen screenshot Debian / Ubuntu GNU Linux

mail admin tool matv1 postfix web mail admin tool debian gnu linux wheezy

Here is how to install

cd /var/www;
wget -q http://mat.ssdata.dk/files/MATv1.1.tar.gz
tar -zxvvf MATv1.1.tar.gz
mv "MAT v1.1" mailadmin
cd mailadmin
cd includes
wget -q https://www.pc-freak.net/files/postfix/postfix-webadmin/config.php.txt
mv config.php.txt config.php
cd /var/www/mailadmin
wget -q https://www.pc-freak.net/files/postfix/postfix-webadmin/index-matv1.php.txt
mv index-matv1.php.txt index.php
chown -R www-data:www-data /var/www/mailadmin

Now point your browser to:
 

 

http://localhost/mailadmin/

or

http://xxx.xxx.xxx.xxx/mailadmin/

(where xxx.xxx.xxx.xxx is your local or Internet IP address) and you should see Matt mailadmin popup. I hope my little tutorial will be of use to many. Comments and problems with install steps will be much appreciated and might lead hopefully to improvements of this little Postfix Install Wheezy tutorial Enjoy 🙂
 

9. Configuring Web mail access to Mail server Mailboxes with Squirrelmail and Roundcube

a) Configuring Squirrelmail to work with Postfix

 

apt-get install –yes squirrelmail
ln -s /etc/squirrelmail/apache.conf /etc/apache2/conf.d/squirrelmail.conf
squirrelmail-configure


Squirrelmail config options default folder config none postfix debian wheezy linux

(Select option 3) – Folder Defaults

Choose Option 1 – Press 1
and set (Default Folder Prefix) to 'none'.

You can take few minutes to browse to other options too to select for example some meaningful title for your Squirrel Webmail – i.e. organization name or whatever…

That's all now to access Squirrel open in Firefox:

http://mail-domain.org/squirrelmail/

To test squirrel is configured correctly try to login with user john@example.org with pass summersun

b)Configure Roundcube + Postfix + Dovecot

Edit /etc/roundcube/apache.conf and uncomment:
 

#Alias /roundcube /var/lib/roundcube

to

Alias /roundcube /var/lib/roundcube
Then restart Apache:

 

/etc/init.d/apache2 restart
 …

 10. Testing if everything works fine together

a) Testing if mail server defined domain has properly configured DNS – PTR, MX and TXT records

First I assume here that mailserver has proper configured PTR record and it is defined properly in DNS to be MX (Mail Exchange server). You will have to contact your ISP (Internet Service Provider) and ask them to create new PTR record corresponding to hostname of mail server defined in myhostname var in /etc/postfix/main.cf
To test whether you have PTR record run:

host 83.228.93.76
www.pc-freak.net has address 83.228.93.76
www.pc-freak.net mail is handled by 0 mail.www.pc-freak.net.
root@websrv:/etc/dovecot# host 83.228.93.76
76.93.228.83.in-addr.arpa domain name pointer www.pc-freak.net.

In above example you see my domain www.pc-freak.net has proper defined PTR record. To test you have defined in domain DNS server (zone files) proper MX record issue:
 

host -t MX www.pc-freak.net
www.pc-freak.net mail is handled by 0 mail.www.pc-freak.net.

Again for sake of testing you see www.pc-freak.net has defined MX with priority of 0 (which in those case is highest), since there are no other defined MX domains and priorities.

It is good practice that domain name has also proper SPF record this is done with DNS server zone record of type TXT. 
Once again here is SPF record defined for www.pc-freak.net.
 

host -t TXT www.pc-freak.net
www.pc-freak.net descriptive text "google-site-verification=j9d4Bt5c_1ukGf4WBng0i4esOqJtbxSFVkG144dFqv4"
www.pc-freak.net descriptive text "spf1 a mx ptr ip4:83.228.93.76 -all"

You see 2nd line is the actual SPF record
www.pc-freak.net descriptive text "spf1 a mx ptr ip4:83.228.93.76 -all"

First line command returns is actually Domain DKIM key. I tried configuring DKIM keys following ISPMail tutorial unsuccesfully so by installing Postfix by my tutorial you will not have to have  DKIM keys (soft) installed or TXT records for Domain Keys defined.
 

b) Testing if mail server is able to send (deliver) mails to other MTA's correctly Next to test whether postfix is sending mails properly use:
 

mail -s "This is a simple test mail, no need to reply" systemexec@gmail.com
Heya,

Do you get this mail
?
Hope so 🙂
.
Cc:

Note that after writing the email you have to press "." and then Enter to send the mail.

To check everything is fine with sending the mail check in /var/log/mail.log, there should be something like;

Aug 2 08:29:56 websrv postfix/smtpd[16228]: connect from localhost[127.0.0.1]
Aug 2 08:29:57 websrv postfix/smtpd[16228]: 0D323662499: client=localhost[127.0.0.1]

Aug 2 08:29:58 websrv postfix/qmgr[14241]: 0D323662499: removed

As you see from above output gmail server returned status of  "Success" – 250 2.0.0 Ok: quequed as 0D323662499 – this means email is delivered OK and if the mail server IP from which you're sending is not listed in some Mailserver IPs Blacklist mail should arrive in a sec.

c) Testing if Dovecot POP3 and IMAP protocol are accessible by SQL kept mail accounts

Last thing to test is Dovecot (for Qmail users for sake of comparison – Dovecot is like Couirier IMAP and Courier POP3 mail server):

To test IMAP and POP3 easiest way is to use simple telnet connections. I've earlier written a small article on How to test if IMAP and POP3 mail service is working with telnet connections, so if you never done this take 2 mins to read it. By default ISPMail adds an email with username john@example.org with password summersun


telnet localhost pop3
Trying ::1…
Connected to localhost.
Escape character is '^]'.
+OK Dovecot ready.
USER john@example.org
+OK
PASS summersun
+OK Logged in.
quit
+OK Logging out.
Connection closed by foreign host.

To test IMAP protocol login

telnet localhost imap
Trying ::1…
Connected to localhost.
Escape character is '^]'.
* OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE STARTTLS AUTH=PLAIN AUTH=LOGIN] Dovecot ready.
01 login john@example.org summersun
01 OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS SPECIAL-USE QUOTA] Logged in
^]
telnet> quit
Connection closed.

Well this is the end my friend 🙂 You should now have a properly running Postfix + Dovecot + Virtual Domains in SQL. Please drop me a thank you comment if it worked for you. If it doesn't drop a comment so I can integrate it and improve this tutorial. Happy Hacking 😉

How to configure pine (alpine) console client to work with vpopmail pop3 and imap protocol

Monday, June 13th, 2011

I needed to check my mail via ssh connection, as my installed squirrelmail is curently broken and I’m away from my own personal computer.

I did some online research on how this can be achieved and thanksfully I finallyfound a way to check my pop3 and imap mailbox with a console client called alpine , better known in unix community under the name pine .

I installed pine on my Debian with apt:


debian:~# apt-get install alpine

Here is my pine configuration file .pinerc used to fetch my mail with pine:

a .pinerc conf file to check my pop3 mail

To use that file I placed it in my home directory ~/ , e.g.:


debian:~# wget https://www.pc-freak.net/files/.pinerc
...

To attune the pop3 server configuration in the sample .pinerc above one needs to change the value of:


inbox-path=

For example to configure pine to fetch mail from the pop3 server mail.www.pc-freak.net and store it locally in my home directory within a file called INBOX
I have configured the inbox-path .pinerc variable to look like so:


inbox-path={mail.www.pc-freak.net/pop3/user=hipo@www.pc-freak.net}INBOX

In above configuration’s inbox-path variable configuration the /pop3/ specifies I want to fetch my mail via the pop3 protocol , if one wants to use imap this has to be substituted with /imap/

The value user=hipo@www.pc-freak.net specifies my vpopmail created user which in my case is obviously hipo@www.pc-freak.net

The other variables which are good to be changed in .pinerc config are:


personal-name=

This variable has to be set to the name of the Email Sender which will be set, if pine is used to send email.

I also changed the user-domain variable as it’s used to set the domain name from which the pine client will send the emails from:

As my domain is www.pc-freak.net I’ve set the domain name variable to be:


user-domain=www.pc-freak.net

Now after launching pine it prompted me for my email password, putting in the pass did fetch all my new unread mails via pop3 protocol.

The only annoying thing was that each time I quit pine and start it up again, I’m now asked to enter the email password.

This behaviour is really shitty, but thanksfully one can easily workaround that by letting pine be constantly running detached in gni screen session.
