I think it is much better to bounce then just quarantine the messages.  If
it does get a false positive at least the sender will know that something
went wrong and the message failed to go through.  Tagging is a good option
for power users but your typical user just gets annoyed and never figures it
out. We block in sendmail.cf with Spamcop and Ordb with decent results.
