Few days ago we had a server maintenance.
The system was shutdown, we fix the CPU fan, and start the system again.
But somehow when the system starts, our IMAP server - dovecot is not running. It just sit like a rock.
Because the machine had a CPanel/WHM, I tried to restart dovecot using cpanel and got a message:
imap has failed, please contact the sysadmin (result was "dovecot is not running").
That was not really useful....
when I tried to restart dovecot using command line, I got nothing. really nothing.
root@machine [~]# /sbin/service dovecot restart
I've been checking /var/log/messages and /var/log/maillog and both give me nothing about dovecot. Not even a single line. Previously I got some log from dovecot to /var/log/maillog
Can anyone tells me how to find out what happens to my IMAP/dovecot? And anyway to make it run again?
I'm using CentOS 5.5 X64 with dovecot 1.2.16
