Heartily agreed. Site-wide bayes here (single database for 2000+

But what is the FP rate? Is it safe for an ISP with a widely varied
user base to use site-wide Bayes?
I find that you should reduce scores on the high and low end (bayes_00
and bayes_95) and the 'meta rules' that might combine them also.
(so, yes, an ISP, or for our hosted clients, we have modified the bayes
scores. . if one client is a plastic surgeon, one is a stock broker,
and one is a mortgage broker, each will be getting wildly different ham)
setting up a 'per domain' bayes might work, might be tricky, especially
if an inbound email is going to several domains, and only if you are
doing B2B (commercial clients)
