Hey ! I have a problem with sending mail via my SMTP-server. Here is the log:
Code:

It sounds like wrong credentials, but I`ve checked endless times. Also, the same SMTP-settings works fine in other applications. I talked to our IT, no generell problem with SMTP.
Any ideas?
I am having SMTP problems as well, got the GUI option set to debug, but I can not find the debug log. Can you tell me how you got your debug messages to show and where?
I go to user -> groups -> sent message to all users in groups and the system just hangs and I get a timeout. I disabled selinux to be sure but no luck and no denied logs in audit.
