Smtp auth 550 relay not permitted fix for roundcube exim4

As there are many none working answers floating on the net here is a solution that will fix the issue for most of you:

 

Locate the configuration file of roundcube defaults.inc.php or main.inc.php:

/var/lib/roundcube/config/ (1.2)

or /etc/roundcube

 

Then change the smtp_server:

FROM

$config = ‘localhost’;

TO THIS

$config = ‘127.0.0.1’;

OR

$config = ‘xx.xx.xx.xx’; (replace xx your external server IP)

That should fix the issue with sending mail from roundcube.
