If you want to know if mail is finally out the door, turn on the
DSN "success" notify option.
As for multiple error/warning notifications: over my dead body !!
What you are asking for is a message multiplier: one message goes
into Postfix, N messages come out. At least, that is what you hope
will happen.
But you don't control everything, especially not those pesky users,
and occasionally one message starts looping around and things blow
up.
Message multipliers are problematic. In the context of email, a
well-known example is the mailing list. And indeed, a bunch of
tricks has been developed to avoid explosions due to forwarding (by
a naive user, or software written by a navive programmer).
Message multipliers are unsafe. Don't do it.
