exim-imap down? WHM

Have you ever experienced exim and imap being down on your server and never really found a fix for it? Well you have come to the right place, there can be many reasons why exim and imap are down, mostly due to the fact that a client/user on your server is mass mailing over thousands of emails which the server cant withstand.

The first step you have to do is delete the delivery que:

You can do that do that be doing this following command :
# exim -bp | awk '/^ *[0-9]+[mhd]/{print "exim -Mrm " $3}' | bash

After you do that, restart your exim server and it should work, unless you had an similar issue I had where the server wouldnt do it properly.

Step 2. This step will fix the issue with imap and exim being down.

*First of all login to whm with your root.
*Find “Mailserver Selection” and click it.
*And choose Courier instead of Dovecot (since dovecott always has issue with centos for some odd reason)
*Click Save.
* Viola You should have you exim and imap back up again.

PS: The changing of mail server can take from up to 10 mins to 20 mins so be patient.

Hope this has helped anyone with their server problems.
