Can you identify spam with a single glance at the e-mail's subject? The Subject Analyzer looks at the spacing, capitalization, and looks for the legally required, but rarely used "ADV" (Advertisement) to determine whether a message is spam. Spammers also use tricks so that it is more difficult for large ISPs to screen out spam by just the subject. They tack on a unique sequence of letters or numbers to the end of the subject so the subject is always different for each message. The Subject Analyzer also looks for that little trick.

The Subject analyzer looks at spam-like characteristics of the subject of a message. You can change the maximum number of points that this analyzer can contribute to the total score. Very seldom will a subject be blatant enough to warrant the maximum score.

Points for ADV - The text 'ADV:' is supposed to appear on advertising e-mails. If everyone did this like they are supposed to, there would be no need for Spam Sleuth. For the few that do, this quickly catches them as spam.

Points for excessive spaces - This catches e-mails with a 'trick' subject. The spammers will tack on some random letters at the end of a subject to keep simple subject filters from filtering them out. Since they put these letters at the end of the subject, there is an excessive number of spaces between the real subject and their little 'trick." This assigns points for that trick.

Points for no subject line - Set the points that will be assigned when a message has no subject line in the header. This is rare, but does happen with some spam.

Points for empty subject - Set the points that will be assigned when a message has an empty or blank subject. This is common with spam, but may also occur when a friend sends you a message and forgets to fill in the subject.

Use Defaults... - Sets Dictionary settings to the defaults.
