This is incorrect. SpamAssassin is a framework within which different
tests to identify spam from ham are applied. Bayesian classification just
happens to be one test SpamAssassin performs but it is by no means the only
test or, in fact, a required test.
Right - lets suppose I'm getting email from truthout.com and I have
50 users who subscribe to that - and it's all ham. Do I want to run
50 copies of the same email through SA and have it learn that 50
times? And have the system slow down processing it? Not if I can help
it.
What I want to do is after a few that Exim learns somehow that this
is all ham and just bless it without having to rerun SA every time.
Exim is at least 1000 times faster than SA and bypassing SA reduces
system load.
Call SA twice. The first call is configured to only run the
auto-whitelist rule
in test mode and not store/learn the results. If the result is a negagtive
score, the sender is in the whitelist and therefore do not call the main SA
function. Note: this will not catch any machines turned into spambots or virus
scanning.
