I just tried to send mail from server command line. That worked just fine.
When i checked mail from what sender it say it was from [email protected]

 

I dubbel checked The perfect server - Ubuntu 15.10 and im not sure if I have done one of the configuration correct.

Then edit the RoundCube config.inc.php configuration file:
nano /etc/roundcube/config.inc.php

and change the default host to localhost:
$rcmail_config['default_host'] = 'localhost';
This prevents that Roundcube will show server name input field in the login form.

I couldn't find "$rcmail_config['default_host'] =" in /etc/roundcube/config.inc.php but i changed $config['default_host'] = ''; to $config['default_host'] = 'localhost';

was that the correct thing to do?

 

Tusen tack Jesse!
hade missat den guiden. Nu har jag fått det hela att fungera
