Only two in over two years.  Not a bad little track record, given that
the lists are _not_ subscribers-only lists.  Independent of the
mailing lists though, cracking down on bogus freemail is something
that will help everyone that receives mail on my server.  A large % of
my total spam value is (or, was) from freemail addresses.

What I ended up doing is refusing mail that claims to be from a
freemail source (e.g, yahoo.com, hotmail.com) but which was relayed
from a non-freemail host.  Legitimate uses of freemail should not be
affected, but this should stop almost all spam sent from a freemail
address.  This was done at the MTA (Postfix) level, not in TMDA.

Except for true read-only lists (such as tmda-announce and tmda-cvs) I
don't like the idea of a subscribers-only mailing list.  They are
extremely inconvenient for non-subscribers to participate in.  This is
where TMDA comes in handy.  It allows non-subscribers to post while
still keeping the list spam-free.
