# My take on this is that it would be very nice to follow
# my 90-10 rule: 90% of the Spam is filtered with only 10%
# of the effort.
#
# With the 90% onslaught filtered out, the remaining 10% can

# This is the reason I saw the difference between the To: and
# the Delivered To: header. Maybe "Delivered-To:" is a Qmail
# thing. But next time you get a Spam message, and it says
# it is for friend@friendly.com, but was actually delivered to
# YOU dfox@belvedere.vip.best.com, then I think you need to look
# at the mail header and see where your real address and the
# To: address differ.
then you would also be deleting mailing list messages
