Scott,

A good add-on test might be a count of punctuation characters in the subject. That would be very close to this suggestion but might be easier to use and require less processing.

 

In particular the drug & "member augmentation" folks are on a tear lately obfuscating subjects this way. In general a legit subject line seldom (if ever) has more than 3 punctuation marks. Obfuscated subjects can have higher than 20 and frequently have higher than 7.

 

Just a thought.

Subject: [Declude.JunkMail] Non-alpha-numeric subject filter

Hi. I've composed a simple but effective subject filter for non-alpha-num characters that are intended to obfuscate words and phrases. It is catching a lot more junk than before. My hold weight is 25 and delete is 35. Forgive me if this is an old idea. Here it is:

 

SUBJECT 6 CONTAINS ~
SUBJECT 4 CONTAINS `
SUBJECT 2 CONTAINS !
SUBJECT 4 CONTAINS @
SUBJECT 4 CONTAINS #
SUBJECT 6 CONTAINS $
SUBJECT 6 CONTAINS %
SUBJECT 6 CONTAINS ^
SUBJECT 2 CONTAINS &
SUBJECT 4 CONTAINS *
SUBJECT 2 CONTAINS (
SUBJECT 2 CONTAINS )
SUBJECT 2 CONTAINS -
SUBJECT 6 CONTAINS _
SUBJECT 2 CONTAINS +
SUBJECT 2 CONTAINS =
SUBJECT 6 CONTAINS |
SUBJECT 6 CONTAINS \
SUBJECT 2 CONTAINS {
SUBJECT 2 CONTAINS }
SUBJECT 2 CONTAINS [
SUBJECT 2 CONTAINS ]
SUBJECT 2 CONTAINS :
SUBJECT 4 CONTAINS ;
SUBJECT 2 CONTAINS "
SUBJECT 4 CONTAINS '
SUBJECT 6 CONTAINS <
SUBJECT 6 CONTAINS >
SUBJECT 2 CONTAINS ,
SUBJECT 2 CONTAINS .
SUBJECT 2 CONTAINS ?
SUBJECT 4 CONTAINS /
