They can, if the list is so configured. Look at zubscribe_policy = auto,
or zubscribe_policy = open with an invalid Reply-To: address. I have no

immediately start getting bounces.

I dunno; this isn't a sendmail list. Try comp.mail.sendmail. My best
guess is that 8.8 does (or can) but nothing else does without hacking
