imap

I ran into several issues with the Roundcube installation on Ubuntu. Roundcube is a browser-based IMAP client that you can install on your server. It’s available from the Ubuntu repository to install. You run this command from the Terminal to install.

Roundcube Install

sudo apt-get install roundcube roundcube-mysql

However, I ran into some issues. The two Roundcube configuration files are main.inc.php and debian.db.php. Both are located in the /etc/roundcube directory. If you have problems receiving or sending mails, it’s worth to take a look at your IMAP and SMTP settings on your /etc/roundcube/main.inc.php file.

Edit the /etc/roundcube/main.inc.php file. Use your own server settings.

sudo nano /etc/roundcube/main.inc.php

IMAP and SMTP Settings

// IMAP server
$rcmail_config['default_host'] = array("ssl://imap.yourmailserver.com");
 
// TCP port used for IMAP connections
$rcmail_config['default_port'] = 993;
 
// SMTP server
$rcmail_config['smtp_server'] = 'ssl://smtp.yourmailserver.com';
 
// SMTP port
$rcmail_config['smtp_port'] = 465;
 
// SMTP username (if required) use %u as the username
$rcmail_config['smtp_user'] = '%u';
 
// SMTP password (if required) use %p as the password
$rcmail_config['smtp_pass'] = '%p';

Use %u and %p if you have multiple accounts.

Database Settings

Make sure your database credentials are correct.

$dbuser='your_username';
$dbpass='your_password';
$basepath='';
$dbname='roundcube';
$dbserver='';
$dbport='';
$dbtype='mysql';

Finally, reboot the Apache server for good measure.

sudo service apache2 restart
