netstat --numeric-hosts --numeric-ports --programs -u -t -l

will list all listening ports and as root also the exectueable

/etc/init.d/dovecot star is they way to go never start a service by it's binary without a good reason without knowing exactly how it is supposed to work

BTW: the dovecot binary lives in /sbin/ not /bin/ [root@srv:~]$ ps aux | grep dovecot root 1843 0.0 0.0 19548 1520 ? Ss 11:58 0:00 /usr/sbin/dovecot -F

i am generally wonder about /usr/local as you said you installed with yum - typically distributions packages are using /usr/bin, /usr/sbin/ and not /usr/local

Never mind. The command /etc/init.d/dovecot start would work; however, something else is using the port. Tracking it down. John
