Exim service cPanel error

Question

I cleaned out some logs from my cPanel dedicated server. I deleted all log listed at that link. Problem is with EXIM process it can not shut down, but it can run. When I try to send Email from roundcube, horde or via smtp it is down. 25 port is down, I can not receive, or send mails. But 1 minute before cleaning logs I received mails and I could send mails. What is the problem, I just deleted logs...

When I try service exim restart I get:

Shutting down clamd:                                       [  OK  ]
Shutting down exim:                                        [FAILED]

Answer 1

I fixed problem changing Courier to Dovecot and then Dovecot to Courier back and that recreated the Courier after that I restarted the Exim with the command:

service exim restart

Now everything works like a charm.
