Log to be checked if using roundcube

 

tail -fn0 /var/cpanel/roundcube/log/errors

 

That's the error - "[04-Jun-2011 02:51:01 +0400]: IMAP Error: Login failed for contact @ koh.ro from 95.76.242.5. AUTHENTICATE PLAIN: Authentication failed. in /usr/local/cpanel/base/3rdparty/roundcube/program/include/rcube_imap.php on line 192 (GET /cpsess7117936613/3rdparty/roundcube/index.php)"

Fix

Please go to WHM > Change Hostname and ensure to re-save the new hostname. After doing that, move these files:

Code:
cd /etc
mv userdomains userdomains.bak110603
mv trueuserdomains trueuserdomains.bak110603
mv domainusers domainusers.bak110603
After moving those files, then run this command:

Code:
/scripts/updateuserdomains
You will get messages about the files you've moved no longer existing. Those files will be recreated by the command.
