I just switched off SpamAssassin here because what had been an equal
number of false positives and false negatives has instead proven to be
nearly every spam not already filtered by my own Evolution filters and
local blacklisting of a swath of worst-offender smtp-refuser getting
through, while most commercially provided requested mailings are getting
flagged. I've been far less than impressed by the tremendous
inconsistency of it respecting the whitelist on my system - only a
couple of entries has it ever applied, and even there, it depends on the
day and what else is happening in the message.

I think SpamAssassin is a great idea, and it may work well for many, but
it is spam filtering like you and I and everyone else are already doing,
and if we haven't been able to write our own filters to catch the
offending messages, leaving it to someone else is not some magic surety
to solve the problem. I'm going to try and re-write some of the
valuations and some additional rules over the next few weeks as time
permits, but that is no guarantee that it will be anymore effective for
my experience. If it does help, I'll offer them upstream to make it more
effective, because I'd rather see it work for as many as possible,
rather than treat it as Micro$oft quality software.
