Well, I know it should, but it does not. Maybe it is something different.

I changed my init.d in July 2008, but unfortunately I do not find anything 
I posted in the mailinglist.

There is no sign in the logs, regardless of the auth_debug or mail_debug 
setting. A telnet to port 143 just hangs without any "connected".

However, this is Dovecot v1.0, so I see no reason to dig into it.
