Multinet implements an SMTP server as per RFC821. This delivers mail directly
into VMS MAIL mailboxes using the foreign mail protocol provided in the
VMS MAIL API. There is no mapping between different address formats required.
The Multinet SMTP server is not as capable as a proper mail server like PMDF
but it should be possible to get it to interoperate correctly with any other
properly implemented SMTP mail server without requiring extra gateways or
system at microvax3100.vintagecomputer.net should be an acceptable email address
to the Multinet SMTP server if it is correctly configured to accept mail for the
microvax3100.vintagecomputer.net domain and the sending mail server knows how
to route mail for it.
In the early days, DEC probably needed some sort of special mapping because
they were likely already using DECnet style email addresses internally when
their connection to the internet came along. Two different email networks
with two different addressing formats were being brought together. This is
not the case here. Only SMTP format addresses are being used.
