source routing is a SHOULD NOT in RFC 2821, so this is not generally
possible.

let me try with an example going into more detail:
[EMAIL PROTECTED] sends e-mail to [EMAIL PROTECTED] this is a list
run the old-skool way, in aliases it looks like:
discuss: :include:/etc/lists/discuss
discuss-request: [EMAIL PROTECTED], [EMAIL PROTECTED]
owner-discuss: discuss-request
when two.example receives the message, it rewrites the envelope header
to be [EMAIL PROTECTED] one of the members of the list is
[EMAIL PROTECTED] unfortunately, e-mail to charlie bounces, so
two.example will send a bounce to the sender, which is now
owner-discuss. this expands to alice and bob, and is delivered as a
single bounce to those two recipients from two.example to three.example.
