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
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?
