Maybe like this?

1.) Host "mail.a.com" hast an alias "foobar@..." which contains "1@..."
    and "2@...".

2.) Host "mail.a.com" send an e-mail to "non@..." which bounces
    with "foobar@..." as the sender.

3.) Host "mail.a.com" delivers the bounce to "foobar@...", expands it
    to "1@..." and "2@..." and tries to deliver that to "mail.b.com".

	Kind regards
