17 Install fail2ban

This is optional but recommended, because the ISPConfig monitor tries to show the log:

apt-get install fail2ban

To make fail2ban monitor PureFTPd and Dovecot, create the file /etc/fail2ban/jail.local:

vi /etc/fail2ban/jail.local

[pureftpd]

enabled  = true
port     = ftp
filter   = pureftpd
logpath  = /var/log/syslog
maxretry = 3


[dovecot-pop3imap]

enabled = true
filter = dovecot-pop3imap
action = iptables-multiport[name=dovecot-pop3imap, port="pop3,pop3s,imap,imaps", protocol=tcp]
logpath = /var/log/mail.log
maxretry = 5

Then create the following two filter files:

vi /etc/fail2ban/filter.d/pureftpd.conf

[Definition]
failregex = .*pure-ftpd: \(.*@<HOST>\) \[WARNING\] Authentication failed for user.*
ignoreregex =

vi /etc/fail2ban/filter.d/dovecot-pop3imap.conf

[Definition]
failregex = (?: pop3-login|imap-login): .*(?:Authentication failure|Aborted login \(auth failed|Aborted login \(tried to use disabled|Disconnected \(auth failed|Aborted login \(\d+ authentication attempts).*rip=(?P<host>\S*),.*
ignoreregex =

Restart fail2ban afterwards:

/etc/init.d/fail2ban restart

 

18 Install SquirrelMail

To install the SquirrelMail webmail client, run

apt-get install squirrelmail

Then create the following symlink...

ln -s /usr/share/squirrelmail/ /var/www/webmail

... and configure SquirrelMail:

squirrelmail-configure

We must tell SquirrelMail that we are using Dovecot-IMAP/-POP3:

Afterwards you can access SquirrelMail under http://server1.example.com/webmail or http://192.168.0.100/webmail:

IMPORTANT

This is very basic but important to you, and for your hosting account later to play with php script

After install and configure SquirrelMail, go to http://your_ip/webmail/src/configtest.php

 

And you will see:

ERROR: You have configured PHP not to allow short tags (short_open_tag=off). This shouldn't be a problem with SquirrelMail or any plugin coded coded according to the SquirrelMail Coding Guidelines, but if you experience problems with PHP code being displayed in some of the pages and changing setting to "on" solves the problem, please file a bug report against the failing plugin. The correct contact information is most likely to be found in the plugin documentation.

 

So please change the php configuration at these two files:

/etc/php5/apache2/php.ini

/etc/php5/cgi/php.ini

 

Find and change the value of short_open_tag from Off to On

short_open_tag=On

 

For more information, you can check here:

http://php.net/manual/en/ini.core.php#ini.short-open-tag

It's a basic php configuration, but might be the one of problems with people that use SquirreMail.

By default short_open_tag is set to On in both php.ini files you mention...

In the file   jail.local

 filter = pureftpd       should be     filter = pure-ftpd   

else  fail2ban ..fails to start

Only if you want to use the default file contained in the Debian package. If you want to use the file created in this tutorial, then filter = pureftpd is correct.
