Bayes.)

FWIW I'm now running this nightly on a pair of systems with a global
AWL, in order to keep it from ballooning to hundreds of megabytes and
bogging down mail processing.
Six years or so after gutting the check_whitelist script from SA ~2.5x
(IIRC) to create trim_whitelist to actually reduce the AWL file size, my
hack is still working. <g>
On another (much larger) system, I've recently activated a global AWL in
MySQL instead, so adding a column to indicate the time the entry was
added allows me to more easily expire entries. Searching back through
the list archives for a subject of "Reduce Bayes DB" should turn up the
suggestions I used as reference.
