Many thanks for the advice. I'm a tad confused at this point as I don't really know enough about how Courier communicates with other mailservers. There is no "me" file so above commands just gave the FQDN for the server machine hta21.trinity.asn.au. This is not accessible directly from outside the LAN. All external email to domain trinity.asn.au is directed to our external IP address, and we forward port 25 from the router (which I gather would be a typical small system setup). I have set the defaultdomain file to trinity.asn.au and that appears to work fine. We have been running Courier-MTA for 2 and a half years without any apparent connection problems, certainly nothing visibly associated with DNS resolution. We also have the esmtphelo file set to mail.trinity.asn.au which is not a machine inside the network - it is just a dummy identifier. Is it that Courier is sending DSNs with the full machine hostname that is causing this? I haven't tried setting the me file as I'm still unsure what I'm doing. I'll readup a bit more over the weekend. cheers, Ken > > If that's the problem, you should create /etc/courier/me or fix your DNS > records.
