Create a startup skript /etc/init.d/pysieved:

#!/bin/sh
 
case $1 in
        start)
        /usr/bin/python /usr/local/lib/pysieved/pysieved.py
        echo "Starting sieve daemon: pysieved."
        ;;
        stop)
        kill $(cat /var/run/pysieved/pysieved.pid)
        echo "Stopping sieve daemon: pysieved."
        ;;
        *)
        echo "Usage: /etc/init.d/pysieved {start|stop}"
        ;;
esac

Set execute permission to the file:

 > chmod +x /etc/init.d/pysieved

Create the file /usr/local/etc/pysieved.ini with following content:BR (There are uids and gids 'hardcoded'. The uid must be changed to the uid of the vmail user and the gid to the gid of the mail group. Debian IspCP defaults are: uid 1001, gid 8)

[main]
auth    = Dovecot
userdb  = Dovecot
storage = Dovecot
 
port    = 2000
 
pidfile = /var/run/pysieved/pysieved.pid
 
[Virtual]
base = /var/mail/virtual/
 
uid = 1001
gid = 8
 
hostdirs = True
 
[Dovecot]
mux = /var/run/pysieved/auth
master = /var/run/pysieved/auth-master
 
sievec = /usr/lib/dovecot/sievec
 
scripts = .pysieved
 
uid = 1001
gid = 8

Open your /etc/dovecot/dovecot.conf and add this line

mail_plugins = cmusieve

to the “protocol lda” like this:

protocol lda {
postmaster_address = postmaster@yourdomain.tld
auth_socket_path = /var/run/dovecot/auth-master
mail_plugins = cmusieve
}

After that add the following lines to end of the file:

auth pysieved {
mechanisms = plain
passdb sql {
args = /etc/dovecot/dovecot-sql-domain.conf
}
 
userdb sql {
args = /etc/dovecot/dovecot-sql-domain.conf
}
 
passdb sql {
args = /etc/dovecot/dovecot-sql-subdomain.conf
}
 
userdb sql {
args = /etc/dovecot/dovecot-sql-subdomain.conf
}
 
socket listen {
client {
path = /var/run/pysieved/auth
mode = 0660
user = vmail
group = mail
}
 
master {
path = /var/run/pysieved/auth-master
mode = 0660
user = vmail
group = mail
}
}
 
user = vmail
}

Change the following line in /etc/postfix/master.cf accordingly:

dovecot unix - n n - - pipe
  flags=DRhu user=vmail:mail argv=/usr/lib/dovecot/deliver -f ${sender} -d ${recipient}

Be careful with the line above. There is a space where

> cd /var/www/ispcp/gui/tools/webmail/plugins/ 
> svn export https://email.uoa.gr/repos/squirrelmail/avelsieve/main_plugin/trunk/ avelsieve

add following line to /var/www/ispcp/gui/tools/webmail/config/config.php below the already defined $plugins. (26 is the correct index for new ispCP installation. If you have added some plugins you have to change the number accordingly)

$plugins[26] = 'avelsieve';

set the correct permissions:

> chown -R vu2000:www-data /var/www/ispcp/gui/tools/webmail/plugins/avelsieve/

create config file:

> cd /var/www/ispcp/gui/tools/webmail/plugins/avelsieve/config
> cp config_sample.php config.php

the following configuration item has to be changed in the config.php:

$avelsieve_striproot = 'INBOX.';

8. Fix a problem with imap namespaceBR (This is only nescessary if you use dovecot 1.0. In version 1.1 of dovecot, deliver supports the namespace prefix INBOX.)

Add the following lines to the fileBR /var/www/ispcp/gui/tools/webmail/plugins/avelsieve/include/sieve_buildrule.inc.php after case '5': (around line 560)

if (substr($rule['folder'],0,6) == 'INBOX.') {
 $rule['folder'] = substr($rule['folder'],6);
}

> /etc/init.d/pysieved start
> /etc/init.d/dovecot restart
> /etc/init.d/postfix restart

> update-rc.d pysieved defaults 92 08

You should now find a register Message Filtering in the 'Options' menu from squirrel mail where you can add your server based filtering rules.

If your squirrelmail is installed in another language as en_US you translate avelsieve too:

> apt-get install gettext
> cd /var/www/ispcp/gui/tools/webmail/plugins/avelsieve/po
> ./compileallpo
> ./xgetpo
> /etc/init.d/apache2 restart

But the translations are not very complete. Updated german language-file is available in the board: http://www.isp-control.net/forum/new-german-languagefile-for-avelsieve-t-2130.html
