Mark, Have a look on RHESUS::, in the MEDIALIB dir there's a whole SPL, I think MAILBUS might be there, in fact: RHESUS::DKA0:[SYS0.FAL$SERVER.MEDIALIB.AXP.SPL.DISK4.MTA030] might be just the thing you're looking for.

Does anyone know where I could lay my hands on: HP OpenVMS Enterprise Directory v5.4 and HP Administrator for Enterprise Directory v2.2 HP MAILbus 400 MTA & SDK v3.2-12 It's more than a little annoying that the hobbyist licence PAKs give you access to tons of stuff that is a nightmare to track down.
