You may be wasting your time - this is a "stealth-mailer" out there
that uses some mis-features in the smail mail package to obscure the
true source of the mail.  By blocking the direct accesses all that
will happen is other methods will be found to circumvent them.  I
suppose it is sort of like putting a "no junk mail" sticker on your
snail-mail box, if the junk mailer really wants to they can stuff your
box full of junk mail anyway.

Perhaps what we need is the electronic equivalent - I suppose
something like the "ESMTP Spoken Here", say "EJUNK mail accepted".
