No, Dovecot tries to find the self by bind()ing to all the listed IPs, and assuming that the first one that succeeds is self. Apparently in your system bind() succeeds for non-self IPs as well. Any idea why?

I think I recently found out about some nicer way to check if an IP belongs to the local system, but I seem to have forgotten what it was.
