When someone foolishly misconfigures MTAs to send notices to the
header "From:" address, rather than the envelope address, I promptly
unsubscribe them from the postfix-users list.
Just because someone posts to the list, does not mean that he wants
to receive notifications for every failed delivery to random
subscribers he had no specific intention to address.
The ONLY case in which notices are sent to a header sender, is with
MDN requests, which are at the interactive discretion of the reader,
and the reply address is "Disposition-Notification-To:" not "From:".
All automatically generated notices, MUST go to the envelope sender,
and MUST obey the constraints imposed by RFC 3834.
Misconfigured "out-of-office" notifications that are sent to "From:"
are a prime example of lack of clue in this respect.
