Для справки

Sieve — язык описания правил фильтрации для почтовых сообщений. Создан компанией
Cyrusoft International, Inc./ISAMET во время работы над Cyrus IMAP server.

Версии используемого программного обеспечения:

DirectAdmin: 1.40.3
CustomBuild 1.x
Exim: 4.77
dovecot: 2.1.3
RoundCube webmail: 0.7.2
dovecot-2.1-pigeonhole-0.3.0

1. Настройка Dovecot

Идем на http://pigeonhole.dovecot.org/download.html и выбираем для своей версии Dovecot соответствующую версию pigeonhole.

Pigeonhole is the name of the project that adds support for the Sieve language
(RFC 5228) and the ManageSieve protocol (RFC 5804) to the Dovecot Secure IMAP
Server. In the literal sense, a pigeonhole is a a hole or recess inside a dovecot for
pigeons to nest in. It is, however, also the name for one of a series of small, open
compartments in a cabinet used for filing or sorting mail. As a verb, it describes the
act of putting an item into one of those pigeonholes. The name `Pigeonhole'
therefore well describes an important part of the functionality that this project adds
to Dovecot: sorting and filing e-mail messages.

И так:

cd /usr/local/src
wget http://www.rename-it.nl/dovecot/2.1/dovecot-2.1-pigeonhole-0.3.0.tar.gz
tar -zxvf dovecot-2.1-pigeonhole-0.3.0.tar.gz
cd dovecot-2.1-pigeonhole-0.3.0
./configure --prefix=/usr
make && make install

Переходим к конфигурации dovecot 

cd /etc/
cp ./dovecot.conf ./dovecot.conf-bak

Открываем /etc/dovecot.conf для редактирования и добавляем

service managesieve-login {
  inet_listener sieve {
    port = 4190
  }
  service_count = 1
  process_min_avail = 1
  vsz_limit = 64M
}
service managesieve {
  process_limit = 10
}
protocol sieve {
    managesieve_max_line_length = 65536
    managesieve_implementation_string = dovecot
    log_path = /var/log/dovecot-sieve-errors.log
    info_log_path = /var/log/dovecot-sieve.log
}
plugin {
    sieve = ~/.dovecot.sieve
    sieve_global_path = /var/lib/dovecot/sieve/default.sieve
    sieve_dir = ~/sieve
    sieve_global_dir = /var/lib/dovecot/sieve/global/
}
protocol lda {
    mail_plugins = $mail_plugins sieve
    postmaster_address = postmaster@server.nsk21.ru
    hostname = server.nsk21.ru
    auth_socket_path = /var/run/dovecot/auth-master
    log_path = /var/log/dovecot-lda-errors.log
    info_log_path = /var/log/dovecot-lda.log
}
protocol lmtp {
    mail_plugins = $mail_plugins sieve
    log_path = /var/log/dovecot-lmtp-errors.log
    info_log_path = /var/log/dovecot-lmtp.log
}

Находим строку

protocols = imap pop3

и добавляем в неее lmtp sieve

protocols = imap pop3 lmtp sieve

Затем секцию

service auth {
  user = root
}

приводим к следующему виду

service auth {
  user = root
  unix_listener auth-master {
    user = mail
    group = mail
    mode = 0664
  }
}

Создаем файлы логов

# touch /var/log/dovecot-debug.log /var/log/dovecot-lda.log /var/log/dovecot-lmtp.log /var/log/dovecot-sieve.log /var/log/dovecot-lda-errors.log /var/log/dovecot-lmtp-errors.log /var/log/dovecot-sieve-errors.log
# chown mail:mail /var/log/dovecot-debug.log /var/log/dovecot-lda.log /var/log/dovecot-lmtp.log /var/log/dovecot-sieve.log /var/log/dovecot-lda-errors.log /var/log/dovecot-lmtp-errors.log /var/log/dovecot-sieve-errors.log
# chmod 660 /var/log/dovecot-debug.log /var/log/dovecot-lda.log /var/log/dovecot-lmtp.log /var/log/dovecot-sieve.log /var/log/dovecot-lda-errors.log /var/log/dovecot-lmtp-errors.log /var/log/dovecot-sieve-errors.log

Перезапускаем Dovecot и проверяем:

# ps aux | grep -v grep | grep managesieve-login
dovecot  20372  0.0  0.1  44608  2988 ?        S    16:53   0:00 dovecot/managesieve-login

и

# netstat -an | grep LISTEN | grep :4190
tcp        0      0 0.0.0.0:4190                0.0.0.0:*                   LISTEN

2. Настройка Roundcube

cd /var/www/html/roundcube/plugins/managesieve
cp config.inc.php.dist config.inc.php

Открываем /var/www/html/roundcube/plugins/managesieve/config.inc.php

// managesieve server port
$rcmail_config['managesieve_port'] = 2000;

меняем на

// managesieve server port
$rcmail_config['managesieve_port'] = 4190;

Дальше открываем /var/www/html/roundcube/config/main.inc.php

$rcmail_config['plugins'] = array('password');

$rcmail_config['plugins'] = array('password','managesieve');

Заходим в интерфейс Roundcube http://domain.com/roundcube/ -> Настройки -> Фильтры -> Добавить фильр

Если при этом не возникло никаких ошибок, значит все настроено по части Roundcube хорошо. Создадим простое правило, по которому потом будем проверят работу фильтров:

3. Настройка Exim

cd /etc
cp exim.conf exim.conf-bak

Открываем /etc/exim.conf для редактирования, находим строки

address_reply:
  driver = autoreply

и сразу после них добавляем

dovecot_virtual_delivery:
   driver = pipe
   command = /usr/libexec/dovecot/deliver -d $local_part@$domain -f $sender_address -a $original_local_part@$original_domain
   message_prefix =
   message_suffix =
   delivery_date_add
   envelope_to_add
   return_path_add
   log_output
   user = "${lookup{$domain}lsearch* {/etc/virtual/domainowners}{$value}}"
   group = mail
   temp_errors = 64 : 69 : 70: 71 : 72 : 73 : 74 : 75 : 78

Находим строку

transport = virtual_localdelivery

и меняем на

#transport = virtual_localdelivery
transport = dovecot_virtual_delivery

И перезапускаем Exim и проверяем!

# cat /var/log/dovecot-lda.log
Apr 08 17:45:55 lda(po4ta@domain.ru): Info: sieve: msgid=<66523BD3B58443CC93FAEED102FCE7E2@VDS54.RU>: stored mail into mailbox 'INBOX.@vds54-ru'

На этом все!
