[HECnet] Multinet Mail

The format that I found in the Multinet Docs suggested this (for my setup):
larry::SMTP%"kurt at hamm.me"

This routes the email through Larry which is configured for SMTP mail.
Larry takes the mail and sends it out.  When I get the email on the
outside, the from address is: kurt at moe.frugalcomputing.com.  my user on Moe
is kurt, the domain name I am using for this is frugalcomputing.com.

When I reply to this email from the outside, Multinet on Larry translates
the email address to send to kurt on decnet node Moe.

Works like a champ.  The only sticking point is that you basically have to
have an open internet mail relay for the VAX to talk to.  I reduced some of
that risk by only allowing a small subnet on the internet to talk to that
open relay.
