I think being able to that (without the trailing doublequote) came in with
VMS MAIL in V7.something.

If you install PMDF (which also has a hobbyist licence), you get the PMDF MAIL
client which can do this and can also do MIME attachments and is generally a
lot more capable than VMS MAIL.

PMDF can probably help you here too as it is vastly more capable than Multinet
SMTP.  However, there is also a lot to learn.

I'm not quite sure whether SYSTEM at microvax3100@vintagecomputer.net is really
what you need here.  Maybe SYSTEM%microvax3100 at vintagecomputer.net would work,
assuming the mail server for vintagecomputer.net is configured to know how
to route mail for a mail domain called microvax3100.

Also, bear in mind that many mail servers may be configured to reject mails
with convoluted routing such as this as spammers often found ways to abuse it.
