Had the same problem with latest Obsidian on centos 7.
The above didn't work and only resolution for me was to edit:
/usr/share/psa-roundcube/config/config.inc.php
and add:
$config['smtp_auth_type'] = '';
Maybe this change will get lost on the next update so any recommendations would be much appreciated.
Hi @John Karamatsoukas,
/usr/share/psa-roundcube/config/config.inc.php should be affected by the updates.
