I'm not sure if changing /etc/security/limits.conf helps. It's probably only used by PAM when user logs in, so if Dovecot is started in system bootup it's unlikely to have been even read yet. Also I think some OSes override the limits in /etc/init.d/ scripts. Of course, I could be completely wrong in all of the above, I haven't really tested any of it :)
The OP was running Centos, and the Red Hat way of increasing nofile for services is to add the ulimit setting to /etc/sysconfig/dovecot:
ulimit -n 32768This is what we use, and it survives dovecot upgrades (since this is tagged as a configfile in RPM, not as script that will be overwritten on upgrades).
