Exim not starting

[da-vid]

I'm very inexperienced with Linux, so I need a lot of help. But I've Googled this issue for the past hour and tried numerous things, but I seriously cannot find a solution to my problem.

Here's the error email that I get every five minutes:

exim failed @ Mon Dec 21 11:46:45 2009. A restart was attempted automagically.
Service Check Method: [tcp connect]

Failure Reason: TCP Transaction Log:

<< 535 Incorrect authentication data
exim: ** [535 Incorrect authentication data != 2]

The most common solution that came up while Googling was to delete the exim folder in /var/cpanel/serviceauth and restarting cPanel. That didn't work.

Thanks if anyone can help me. I really appreciate it.

Please try rebuilding your exim configuration

/scripts/buildeximconf

and then restarting exim

/scripts/restartsrv exim

If this does not solve the problem, please open a ticket at https://tickets.cpanel.net/submit/

Tried that, didn't work. It said exim started ok, but exim still shows as "failed" under Service Status, and I still get SMTP errors while trying to send emails. I'll open a ticket. Thanks for your help.

EDIT: Now exim shows up as working, but I still can't send emails. I'm going to try some other stuff before submitting a ticket actually.
