   This kind of poster might best be served by having them subscribe and
   set their subscription to no-mail.  This also is a useful strategy for
   members with multiple addresses.

This will not work in my situation for more than a certain percentage of my
non-member posts.  The details aren't important (to this list anyway).

   Please be more specific about "false positive".  If you mean according
   to the default setting of "5.0 is spam", you might still get rid of a
   *lot* of spam by raising that to 10.0 without false positives.

False positive means it's legit mail that is in my spam folder.  Using my
ISP's defaults.

   How does your graymail work?  It sounded to me like it was just
   another moderation box.  Now you have two, as I understand it.  This
   may be a win for you, but I don't see why it would be offhand.

Graymail is a list of from addresses and subject headers of every email
there.  If it's all spam, I scan and ignore.  It goes away forever after 7
days (my setting).

Anything in moderation for MM must be clicked on.  One at a time.  3 clicks
per sender (which means per spam most of the time) if I want to set the
address to auto-discard and ban the spammer from joining the list, in
addition to simply discarding the email.

False positives are far easier to deal with in MM moderation than in
graymail, but my ISP is about to come out with a better version of graymail
that may reduce the workload.
