Is there any functional or semantic difference between an MDA adding
Delivered-To: and an MDA adding a Received: with a 'for' clause containing
the same address? Is it somehow conveying the semantic difference between an
MTA and an MDA?
That's it. If there are address rewrites between the RCPT TO and the
final delivery, it uses the rewritten address.
This is what qmail does. I think Postfix does the same thing, can check.
Also, does adding the Return-Path: happen before or after adding the
Delivered-To:? The spec seems to indicate before, but it doesn't mention
Return-Path: at all.
In practice they're added at the same time.
