Those are both requirements for SMTP MTA's, that is true. But since
nmh isn't doing final delivery, I don't think those things apply.
People smarter than I can speak up, but I think nmh falls more in the
category of a mail _user_ agent, and thus RFC 4409 is more in line with
what nmh should be doing. But specifically:
- Should we retry on an error? Well, yeah, probably. That would be
difficult, I'd think (I believe you would want to back off and not simply
retry right away). Right now we simply notify the user about the failure.
- Since we're not doing final delivery, the server listed in mts.conf file
is not a _domain_ (part of an email address) that we're connecting to, but
the name of server that runs an SMTP service we can use for message
submission. As such, MX records are not appropriate.
Both of these things are things that plenty of other MUAs do. That doesn't
necessarily mean that nmh should be doing them as well, but there is plenty
of precedent.
