VPIM, RFC 2421 suggests using:
non-mail-user(_at_)domain
for unrepliable messages. In this case, message originating from a
telephone-answering application cannot be replied to.
RFC 2421 prohibits replies to this special-case address by conforming
systems.

While discussing a brokked email system at a well-known ISP that is
generating unreplyable messages, a co-worker asked me what the proper
way to *specify* that no reply is to be attempted. I was stumped.
Yes, you can point Reply-To: at a bogus address, or a /dev/null, but
I can't think of any way to specifically flag a message as "FYI only,
no reply desired". Am I just caffeine-defficient today, or is there
in fact no such beast?
And if there isn't, should there be?
For news, draft-ietf-usefor-article-01.txt suggests
Reply-To: <>
analogous to the empty SMTP reverse path, but this isn't RFC822
conformant.
An empty group has valid RFC822 syntax, it might have the desired
effect.
Reply-To: "FYI only, no reply desired":;
