Thanks Robert. That's an interesting idea. It probably isn't really 
worth the hassle as the whole issue is not quite that important. I was 
merely wondering if there is a configuration option for Dovecot to 
ignore missing interfaces.

Maybe coming from the other direction of the spectrum might also be a 
good idea - something like a "nolisten" option - to prevent it from 
listening on certain interfaces. That's the main reason I use the 
"listen" option - to prevent Dovecot from ever listening on certain 
interfaces, as an extra layer of protection in case the firewall ever 
gets misconfigured.
