I would consider anything with a blank To or From as Spam.  Most emails w/o a subject 
(or wth a subject that contains 10 or so spaces in a row) are also Spam.

I have a bunch of other things in our servers here that trigger email as Spam:

1 - we use 3 RBL servers (spamcop, njabl and spamhaus)
2 - mail that has a helo that is the IP address of our mail server or the rdns of our 
server is spam.  For example:

HELO 64.69.103.207 
HELO rabbitt.hoot.com

Spam still comes through but our servers block around 95%

Regards,

Howie
