Managesieve unable to connect to server when trying to install Roundcube autoresponder with Dovecot on Ubuntu

  • 772

In order to establish an autoresponder i'm trying to install filters through activating the plugin Managesieve in Roundcube.

Probably i'm doing something wrong, there's an errormessage in Roundcube saying 'unable to connect to server'

The mailserver and Roundcube are succesfully running, versions: Roundcube 0.9.5 / Postfix 2.11.0 / Dovecot 2.2.9 / Ubuntu 14.04.4

Roundcube errorlog is empty Mail errorlog says: Jul 23 16:06:01 vuyk postfix/submission/smtpd[27845]: fatal: no SASL authentication mechanisms

In /etc/dovecot/dovecot.conf:

protocols = imap lmtp pop3 sieve

In 20lmtp.conf:

protocol lmtp {

  postmaster_address = [email protected]
  mail_plugins = $mail_plugins sieve
}

In /etc/dovecot/conf.d/20-managesieve.conf: 

  protocols = $protocols sieve

 service managesieve-login {
  inet_listener sieve {
    port = 4190
  }
#} <- still commented, this was the problem!

In /etc/roundcube/main.inc.php:

$rcmail_config = array('managesieve');
$rcmail_config['managesieve_host'] = 'localhost';

In /etc/dovecot/conf.d/15-lda.conf:

protocol lda {
  mail_plugins = $mail_plugins quota sieve
}

In /etc/dovecot/conf.d/90-sieve.conf:

sieve = ~/.dovecot.sieve
   sieve_global_path = /var/lib/dovecot/sieve/default.sieve
   sieve_dir = ~/sieve
   sieve_global_dir = /var/lib/dovecot/sieve/

In usr/share/roundcube/plugins/managesieve/conf.inc.php.dist:

$rcmail_config['managesieve_port'] = 4190;

    You have to configure managesieve server from the dovecot bundle:

    ---- dovecot.conf -----
. . . . . 
service managesieve-login {
  inet_listener sieve {
    port = 4190
  }
  service_count         = 1
  process_min_avail     = 1
}
. . . . .

  2. Do not forget to open port 4190 on your firewall:

    firewall-cmd --add-service=managesieve --zone=public
    • 0

  3. In my case it was just

    $config['managesieve_usetls'] = true;

    what's been missing after the server settings were changed to require TLS.
