Ah. Somehow I got confused and was getting the impression that some Windows component or another was using the field to decide where to find the IMAP service. Obviously, if it's Courier that's looking at the field, then of course it would be an internet-style hostname. > On the other hand, if your DNS servers are Windows servers, That's a whole other can of worms. (Did I mention that Active Directory is weird and a pain to deal with?) Generally, all the computers on the Active Directory domain must use as their primary name resolver a server that thinks it is authoritative for the domain and that accepts updates from other computers in a way that would be insecure for an actual authoritative nameserver to do. This is almost always a Windows server, although BIND is also capable of being configured this way. If you do not provide such a nameserver beforehand, the first Domain Controller you install becomes one, so that's a common setup. Usually you handle the resulting security issue by implementing a firewall to the effect that only computers on the AD domain can access said name service at all, and you tell the rest of the world that some other, more sanely configured name server is authoritative for your domain, probably one that doesn't do recursive resolution at all, *certainly* one that doesn't accept updates willy-nilly from just any computer on the network. Fortunately, all of that should be more or less invisible to Courier. As long as it gets the right answer when it does the name lookup, the details of where the answer comes from shouldn't really matter. -- Nathan Eady Galion Public Library ------------------------------------------------------------------------------ This SF.net email is sponsored by Make an app they can't live without Enter the BlackBerry Developer Challenge http://p.sf.net/sfu/RIM-dev2dev _______________________________________________ courier-users mailing list courier-users@lists.sourceforge.net Unsubscribe: https://lists.sourceforge.net/lists/listinfo/courier-users
