I'm new to web admin and I had an issue with squirrel mail not being able to receive mail, i found somewhere that said reinstalling doevcot would fix this and so i did and now i can't even login to squirrel mail.
I'm running Centos 5.6 with Ispconfig 3.
Following is the error log:

I've tried installing another mail client "RoundCube", I've deleted and recreated the mail domain and mailboxes for it, but still nothing. It's as though the mail client(s) can't validate the users details.
