Wrong question, the issue is that not all MTAs implement DSN, so once
Postfix relinquishes the mail to another MTA (which may forward it furter)
all bets are off. Note also that auto-responders may ignore DSN requests...

So basically you get deterministic behaviour while Postfix 2.3 owns the
message, and no guarantees after that.

If my response solves your problem, the best way to thank me is to not
send an "it worked, thanks" follow-up. If you must respond, please put
"It worked, thanks" in the "Subject" so I can delete these quickly.
