[Dovecot] Dovecot wont start.

I installed Dovecot along with Postfix on a FreeBSD server using the port. When I try to start dovecot I get the following error:

Fatal: Can't resolve address : hostname nor servname provided, or not known

I have the hostname define on the server and can ping it by FQDN and by just hostname with out problems.

Any suggestions are greatly appreciated.
