And yet another point where forwarding would break.
Say I have this aliases file on foo.domain
a: b(_at_)bar(_dot_)domain, c(_at_)bar(_dot_)domain
Now, I receive a bounce to a(_at_)foo(_dot_)domain, then I'd usually bundle
the forward into one SMTP transaction, and voilà, you have a MAIL FROM:
<>, with 2 RCPTs.
Receiving a bounce to a distribution alias address would require that the
alias address was used as a MAIL FROM before, which would be very unusual.
(Not saying that it couldn't happen.)
