this is a question not exactly postfix related: When a mail server
is about to send a bounce message to the original sender of an
undeliverable mail - which address will this bounce be sent to?
The Return-Path? The address from the "From" header?
Or even to the "Reply-To" address?
Bounces are always sent to the envelope sender address. That address is
also added as the Return-Path header by the MTA upon final delivery (i.e.
you won't find the Return-Path header on the wire and you can't use that
header to affect where bounces go).
If I recall correctly there used to be a "Mail-Error-To" header, but I
doubt it was ever a standard header.
you probably meant Errors-To. "non-standard, discouraged" (See RFC 2076).
