How do i get the system status to show dovecot and postfix monitors? At present neither are displaying.
From the information below, postfix is running, however, no matter what i try, dovecot continues to fail (i have tried to kill process and restart twice all to no avail. My feeling is that i will have to do a hard reset on the webserver?)
service dovecot status

Delete /var/run/dovecot/master.pid and reboot your server.
Somehow, dovecot was killed or otherwise died leaving its PID file behind (The file contains the pid (process ID) of the supposedly running process). The start/stop script checks if that file exists. Given the file exists, but presumably dovecot is not running, you can safely delete the file and restart dovecot. I suggest rebooting simply to make sure all the other mail processes are happy as well. There is -no- need to hard reset your server.
