I installed Apache, PHP5, MySQL and Webmin on a vps. I host my website on that.

I completely reinstalled whole VPS with fresh installation of Postfix and Dovecot. But Dovecot fails to start, so Roundcube can't connect.

I installed Postfix, Apache, MySQL, PHPMyAdmin, Dovecot using this source:

Need some guidance to bring Dovecot up.

To use roundcube and shown as, you should login roundcube with your full email address If you forget to do so, it will append the full machine name.


In roundcube config, setup the following

$rcmail_config['username_domain'] = '<the-domain-name>';

Go through your webmin interface and learn how to put it in. There is webmin module for roundcube.

Updated answer. If it is configure correctly, login roundcube without the domain portion. – John Siu Dec 28 '12 at 3:15
