No.

I want it to go to the person who manages the machine I connect to. As
the RFC implies.

Well, perhaps you ought to read up the spec, then.

Ah, right, you know enough about mail delivery to do this, then? This is
not apparent from the rest of your messages to the list. The correct
document is RFC2821 dated April 2001.

The paragraph you will want to look at is particularly the Syntax: part
of 4.1.1.3 of this document.

This is true, however most of those are SHOULD rather than MUST. If you
want to interoperate, you play by the rules, if you don't want to
interoperate, not my problem.

I'm amazed that you think "April 2001" is decades ago, and that there are
no mentions of policy in the document in question. Perhaps you ought to
actually read it? I think that if you think you know best then you ought
to join the standards track for mail.
