I just noticed this network rule with very poor performance.  0.02% spam
detected in recent masschecks.

My local logs show 16 hits out of 300K mail scanned in the last several
months, 2 of which were false positives.

Apparently it was performing poorly even in the 3.3.0 rescore masscheck late
2009, with 0.072% spam detected in the much larger sample of the rescore
masscheck.

NJABL and rfc-ignorant.org were controversial at 1% spam, but certainly
*this* is an obvious candidate for removal?

Where should we draw the line?
