PMDF was the engine used there for this task. If you don't anticipate HUGE volume of email, even MX could do this and MX is freeware. So MX can do the subdomain -> decnet node name conversion? Not straight out of the box, but it sounds like something fun to try and set up. MX can do a lot of useful things, including breaking out to a DCL procedure to do message handling. It would be an interesting feature to add though. I guess if I looked in to how MAIL-11 does its business it would be possible to knock up something bi-directional. Regards, Tim.
