EUDORA SPAM FILTER 17
Excessive Spaces in Subject Line
Was: Tracking Code in Subject Header - Revised 1-28-03 Based On Testing

Tracking Codes found in: 12% of spam tested.
4 or More Spaces found in: 16% of spam tested, 0% in friendly email.

Catches: Any email with subject line containing 4 or more spaces.

This is one of only two subject line filters that I use. It finds any message that has 4 or more contiguous  spaces anywhere in the subject line. This will usually be followed by a group of two or more letters and/or numbers. These random looking letter-number groups appear to be codes, possibly for tracking purposes by the "Evil Spam Clowns", and are often way out at the end of the subject line after 30 or more spaces.

Header	Subject:
Verb:	regexp (case insensitive)
Value:	[ ]{4}
Actions:	Transfer To Spam.mbx

NOTE*
The [ ]{4} means to look for 4 spaces. In an actual spam Subject line, the number of spaces will vary widely, from 3 to 30 or more.

Here's two examples of spam subject lines that this filter will catch:

"Your Financial F R E E D O M  Has Arrived!            WCZOQWSIG"
"Useful info re: septic maintenance                                          4396En-6"
