Perhaps I am missing something here.  I find it easy to distinguish type-I
anonymous traffic from nym mail.  Anonymous mail usually comes from an
address like 'anon@' or 'nobody@' while pseudonymous mail will come from a
pseudonym.

A pseudonym is almost indistinguishable from a regular email address.  The
only way you can tell is if your know the domain is a remailer domain.
Since there are very few stable nymservers in the world, it should not be
hard to filter for all of the stable nyms individually.  If I was looking
or a generic way to filter out from all anonymous mail from the 3 to 12
nyms (depending on how you count) on the same domains, I'd look for the
word "anonymous" in the from field.

I successfully filter all anonymous mail I receive, but I assign it a color
rather than rejecting anonymous mail.
