Yes, this is exactly what I mean. Apparrently this is not an uncommon setup, and the current code will only try the aaa.bbb.ccc.ddd address. > > > I believe that I need to do a double loop in RemoteDelivery to solve this > > In my view, it should be done by our DNS lookup code.

Yes, that is exactly what needs to be addressed, the problem of doing it at the DNS lookup level (which I agree is the conceptually right thing to do) is that then the returned addresses (by the getMailServers call) bears no information to the original MX record, and the log-lines from RemoteDelivery gets more cryptic like: James.Mailet: RemoteDelivery: Attempting delivery of Mail1056370039520 to ho st [aaa.bbb.ccc.ddd] to addresses [EMAIL PROTECTED] where I would prefer: James.Mailet: RemoteDelivery: Attempting delivery of Mail1056370039520 to ho st mail at [aaa.bbb.ccc.ddd] to addresses [EMAIL PROTECTED] Now to achive both nice logging and handling of multihornedness. I would (going back to the original question) either add a new method to MailetContext or use DNSServer directly in RemoteDelivery, the easiest (which is what I currently have done) is to add the MailetContext method, but unfortunately this is not just an addition to James but to the Mailet API as well. Not that this bothers me a lot, as additions of methods does not break backwards compatibility. -Søren -- Søren Hilmer, M.Sc.
