I figure I could eliminate about 60% of the junk mail I'm not able to filter
out with Netscape's Mail Filter settings right now simply by detecting a run
of five or more spaces in the Subject line. Netscape won't take lines of
spaces in the filter boxes.  (I'm running 4.61.)

Does Teergrube handle this stuff?

(A simple regex pattern like ".*     *[([].*[)\]].*" would catch a ton of
stuff.)
