smtp mail to/from VMS system

[Steve Brailsford]

I have been trying to set up our network on a Motorola Delta 1147
System.  It runs UNIX System VR3.6.
I have installed cnews2, and nn, and smail3 (with elm).
What I am having problems with is we have a VAX on our ethernet
network.  I have tried to send mail to the Delta from there and
the operator told me my side was denying access.  He told me
mail is transfered via SMTP.  I can't find anything on SMTP in
any of my docs.  Smail talks about it, but only when used with
sendmail, we don't have sendmail of course.  Is there something
I just need to set up to allow SMTP mail?  Or is there a program
daemon that I don't have?
  Thanks, you can email me if it's not general interest, or
it doesn't belong in this group.
