Come now, Dr. Boyes. We've had support to verify the host name on a HELO (and these days, EHLO) since VM/ESA 2.4. See the VerifyClient statement in SMTP CONFIG. It is not active by default since that would be a violation of the SMTP RFCs. And if you don't like our built-in algorithms for verification, you can write an exit to do whatever you like. And, please, no whining about the lack of a shared file system in older versions of VM, either. ;-) Alan Altmark z/VM Development IBM Endicott
