SMTP Error (250): Authentication failed. Cannot Send Email in Roundcube

HP server rack mounted hardware for enterprise data centers.

This only apply after you have installed : TLS/SASL/SSL !

I am using “Virtualmin” so locate your roundcube in here:

/home/[username]/public_html/webmail/config/config.inc.php

Locate this configuration: $config[‘smtp_server’] = ‘localhost’;

Easy fix here!

Remove ‘localhost‘: $config[‘smtp_server’] = ‘ ‘;

Now roundcube will use PHP instead of SMTP

Enjoy!
