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.
Not resolved with the above solutions.
hi
i have to tape exactly the same line of thoose ssh command?
Ikbel Sassi You need to edit the file master.cf and edit it as shown in the output of the egrep command.
