fix:
This has been fixed.
Somehow, I do not know how, files such as my.cnf, exim.conf and my SSH directory were all CHMOD 777.
After the SSH directory and files were set back to 600, I could log in and CHMOD my.cnf and exim.conf back to 600 and bingo, I now have email again and I do not receive the error about my.cnf.
All I remember doing is upgrading WHM/cPanel, then the problems started, no idea how these files got the wrong CHMOD values.
By the way allenhui, what lines are missing from my.cnf? I would like to have that file properly configured.
