[Dovecot] Getting "Can't resolve address no: Name or service not known" error when starting Dovecot

Hi gentlemen!

After running for six month Dovecot 0.99.14 I decided to upgrade to 1.0rc15. Actually Dovecot is running under Slackware Linux 10.2 and I got the package from http://www.linuxpackages.net.

Problems? Yes, one! When I try to startup Dovecot program hung:

Fatal: Can't resolve address no: Name or service not known

I'm not a Dovecot or IMAP guru and I can't imagine what kind of address number (I think is complaining about the machine's IP address) or "name" or "service" that it doesn't know! I googled for the entire afternoon for someone that meet the same problem but I got no interesting clues... Yesterday I installed also iptables and I thought the two things are related so I disabled iptables but... nothing!

Here some valuables (I hope!) informations for the good guys that want to help my desperate soul...

Thank you again and I hope everybody enjoy the Christmas holidays...

Bye! Francesco

P.S.: I hope also that the Dovecot team develop an online documentation that reflect the versatility and complexity of the program.... ;-)
