Standards-bearers,
Let me let RFC 2821, Section 4.4, say it for me:
> When the delivery SMTP server makes the "final delivery" of a
> message, it inserts a return-path line at the beginning of the mail
> data. This use of return-path is required; mail systems MUST support
> it. The return-path line preserves the information in the <reverse-
> path> from the MAIL command. Here, final delivery means the message
> has left the SMTP environment. Normally, this would mean it had been
> delivered to the destination user or an associated mail drop, but in
> some cases it may be further processed and transmitted by another
> mail system.
Yes, I know 2821 is still only proposed, but here's 1123 leaning in
the same direction:
> When the receiver-SMTP makes "final delivery" of a message, then it
> MUST pass the MAIL FROM: address from the SMTP envelope with the
> message, for use if an error notification message must be sent later
> (see Section 5.3.3).
Do some tests and you'll see where I'm coming from.
Arguments, comments, etc. welcomed.
