For my single user case I accept a few false hits for the LKML because
I must filter them or accept that they are a spam relay mailing list
and accept the spam. Otherwise I have about one per week escape the
spam filters and a few people who persist in using broken mailers
falsely trigger the spam filters.
Out of 1200 or so messages per day roughly 100 to 180 are spam and
of that maybe 1 or 2 a week escape the filtering. Of the remaining
hams about 1 or 2 per day from one particular person gets triggered
as spam. Off hand I would say that better than 99.9% spam captured
and less than 0.1% ham falsely tagged is not had at all.
