interesting case, but if you do the check in the ACL on inbound only,
the expansion you do won't affect the test. if the bounce is addressed
to a mailing list (foo-owner), it will be suppressed and handled by the
mailing list software, or passed on with its envelope sender changed to
foo-owner.
there may be an issue with traditional aliases based mailing lists run
on a remote system[1], but where two or more of the list owners are on
your system, but this is so uncommon I think most systems can disregard
it.
(that's my reasoning anyway, I welcome corrections :-)
[1] this includes local workstations running Sendmail with a
custom /etc/aliases, so take care.
