IMAP Email Authentication is Now Failing - Could Use Some Assistance

Marc_Ta

New Pleskian
Running Plesk 10.3.1 on Linux installation....

Had 10 different email addresses all setup and working great for the last couple of days. I noticed issues where using the same email client to access more than one of these email addresses at a time was causing problems, so I followed the instructions in this link --> http://kb.parallels.com/en/113841

No issues updating the file. But once I restarted the courier-imap, authentication doesn't work now for any of the email address (accessing through webmail or through other email client). Passwords have been verified via mail_auth_view and are correct.

The errors I'm getting look like this:

The courier-imap service appears to be running just fine:

[root@0398462 ~]# /etc/init.d/courier-imap status
couriertcpd (pid 1827 1818) is running...

I followed the steps in this article trying to debug --> http://kb.parallels.com/en/6781 but everything looks fine. Any other ideas of what I might be able to check?
 
I just rebuilt the mail server settings, restarted and authentication still isn't working:
