yes, i've seen that happen before.  in fact, i have seen messages
that would be classified as spam while still encoded in base64
be classified as non-spam after unbase64 decoding.  however, this is
very unusual.  i have seen many more instances of base64 spam
that would be non-spam unless decoded.

suzanne's bogopass script would be a useful interim solution
and i think we should include it in the contrib dir.
