Thanks, Steve. I am really trying to forward mail off the VMS box to 
another account, and the easiest way seemed to be MAIL>FORWARD. I guess 
not. I assume such things as POP and IMAP are right out.

How do I set up such a relay (VMS side setup)?  And VMS doesn't know 
SMTP AUTH?

Incoming mail works just fine.  I pointed the MX for a domain I have to 
my ISP's address, and although dynamic, it rarely changed. I originally 
had the VMS box as a normal mail server until the ISP took Port 25 away. 
  It continued to receive email (still does) but I went elsewhere to do 
most of my email. Right now I wanted to forward email I want to save to 
another account, and it appeared updating the VMS configuration was the 
easiest way. I guess not.
