If you'd ask for a personal advise, SORBS is nothing to be trusted as a
blacklist.
I personally don't think bounces should be allowed for an address that
_never_ sends mail or has never sent a mail that require a bounce, while
they still use that trick to send "legitimate" mails. By definition, a
bounce is a response to a mail that has been sent from an address, not
something that should be used as a sender for a fresh new mail. The
latter just deserves to be blocked or discarded.
