Sorry didn't scroll to the bottom to see the dovecot -n. I'm assuming freebsd has an /etc/login.conf similiar to openbsd. If so you may need to do something similiar to this:
dovecot:
:openfiles-cur=512:
:openfiles-max=2048:
:tc=daemon:
Rebuild the login.conf.db file if necessary:
# [ -f /etc/login.conf.db ] && cap_mkdb /etc/login.confHope this helps.

Hi
I keep on getting errors and can't connect/login to Dovecot. I did my research but unfortunately without success. It is for sure not ulimit because ulimit is set to unlimited per default already. Still , it complains about "Too many open files" but this is a test system and the service dovecot and postfix have just been started. No one except me is testing on this system. This is very weired ;/

If I uncoment port = 0 in POP and IMAP then it looks even worse then above. Telnet is not even closed by remote host and three of the "Too many open files" errors are showing up in maillog:

Does anyone have an idea what could be wrong here? I attached the relevant configuration below. I use OpenLDAP as backend. Please let me know if you need more information. Thank you very much.
