Roundcube allows the management of email filter rules through the managesieve plugin. This plugin connects with the dovecot-sieve server and update user filters using a standard protocol. This way the user doesn't have to edit the ~/.dovecot.sieve files directly in its home directory, avoiding possible syntax mistakes.
Filters can be managed throug Roundcube -> Configuration -> Server config -> Filters.
With my setup (Nginx, php5-fpm and Dovecot) these are the necessary steps to configure it.
Activate managesieve server
Install managesieve:
sudo apt-get install dovecot-managesieved
Edit file /etc/dovecot/conf.d/20-managesieve.conf:
service managesieve-login {
inet_listener sieve {
port = 4190
}
}
service managesieve {
}
protocol sieve {
}
Edit file /etc/dovecot/dovecot.conf and activate protocol sieve:
plugin {
sieve = ~/.dovecot.sieve
sieve_dir = ~/sieve
}
protocols = imap sieve
Reload php-fpm application server (if using this method to serve php):
sudo service php5-fpm reload
Check that the managesieve server is really running and listening at port 4190:
sudo netstat -tnlp | grep dovecot
Configure managesieve plugin at Roundcube
Edit /etc/roundcube/main.inc.php:
// List of active plugins (in plugins/ directory)
$rcmail_config['plugins'] = array('jqueryui', 'managesieve');
Copy contents of file /usr/share/roundcube/plugins/managesieve/config.inc.php.dist``to ``/etc/roundcube/plugins/managesieve/config.inc.php and edit it:
$rcmail_config['managesieve_port'] = 4190; $rcmail_config['managesieve_host'] = 'localhost';
