Question

How to configure Horde to authenticate on external server?

Answer

The requested functionality was not tested with Plesk and it is not supported officially. However, you can configure Horde to work with external mail server on your own risk:

  1. Make a backup of /etc/psa-webmail/horde/horde/conf.php .
  2. Replace 'localhost' in $conf['mailer']['params']['host'] parameter with external server name or IP address:
    $conf['mailer']['params']['host'] = 'external_server_name_or_IP';
    $conf['mailer']['params']['port'] = 25;
    $conf['mailer']['type'] = 'smtp';
  3. Backup /usr/share/psa-horde/imp/config/backends.php file .
  4. Change the 'hostspec' parameter to desired external server name or IP address under // IMAP server section:
    // IMAP server
    $servers['imap'] = array(
        // ENABLED by default; will connect to IMAP port on local server
        'disabled' => false,
        'name' => 'IMAP Server',
        'hostspec' => 'external_server_name_or_IP ',
        'hordeauth' => false,
        'protocol' => 'imap',
        'port' => 143,

Please keep in mind that installation of Plesk micro-updates may override the changes.

Note : This configuration is server wide and will be applied for all domains that use Horde on your server.

If you want such functionality to be implemented in Plesk, please provide your suggestion for the new functionality on User Voice . The top-ranked suggestions are likely to be included in the next versions of Plesk.
