Moreover, it is *very* unwise (to say it mildly) to share
Bayesian wordlists -- the biggest strength of Bayesian anti-spam
filters is that it catches *your* spam and that no spammer knows
what *your* spam means, so it cannot defend against that.

The same works in the other way as well -- if you send output of
*any* anti-spam program to Razor you get IIRC kicked out the
system (see Razor FAQ for more and for explanation).

Please, guys, before doing proposals related to something so
complicated as spam (or PGP) do your homework.

        Best,

                Matej
