New Roundcube identities get a '@localhost' domain part for their Email address. That is kind of useless. I would rather have Roundcube take the Apache HTTP host (minus a possible 'www.'), since my users will use 'their' associated domain for getting to the Roundcube interface. How can I configure this?
How to set the default domain for a new Roundcube webmail user?
email;webmail
Found the solution to my problem. In the main config of roundcube (/var/lib/roundcube/config/main.inc.php) you can set the mail_domain variable:$rcmail_config['mail_domain'] = '%d';There are multiple placeholders, but %d will use the web server domain, which is fine for me.
