I don't use Razor or Pyzor partly for this reason, and partly due to delay
issues.
By the way...
When discussing why certain rules have certain scores, the set of scores
that make no sense to me is the scoring given to Bayes:
------50_scores.cf --------------
score BAYES_00 0 0 -4.901 -4.900
score BAYES_01 0 0 -0.600 -1.524
score BAYES_10 0 0 -0.734 -0.908
score BAYES_20 0 0 -0.127 -1.428
score BAYES_30 0 0 -0.349 -0.904
score BAYES_40 0 0 -0.001 -0.001
score BAYES_44 0 0 -0.001 -0.001
score BAYES_50 0 0 0.001 0.001
score BAYES_56 0 0 0.001 0.001
score BAYES_60 0 0 1.789 1.592
score BAYES_70 0 0 2.142 2.255
score BAYES_80 0 0 2.442 1.657
score BAYES_90 0 0 2.454 2.101
score BAYES_99 0 0 5.400 5.400
----------------------------------
Why is BAYES_00 not = -1*BAYES_99 ?
Why would BAYES_70 score higher than BAYES_80 or BAYES_90?
Same with BAYES_20 and BAYES_10.
I can only assume those who trained the Bayes filter before running the GA
trained with a bad corpus.
Also, I felt granularity should be finer as you approach 100% since it takes
a whole normal standard deviation to get from 98% to 99%, and values should
be the same on each side of 50%.
I've updated/rescored the following rules as defined below:
---------------- local.cf ------------------------------
body BAYES_01 eval:check_bayes('0.01', '0.02')
body BAYES_02 eval:check_bayes('0.02', '0.10')
body BAYES_98 eval:check_bayes('0.98', '0.99')
body BAYES_90 eval:check_bayes('0.90', '0.98')
score BAYES_00 -5.4
score BAYES_01 -4.0
score BAYES_02 -3.0
score BAYES_10 -2.5
score BAYES_80 2.5
score BAYES_90 3.0
score BAYES_98 4.0
score BAYES_99 5.4

| Definitely FPs. I think SA has a very difficult time with
| solicited commercial email, even with Bayes feeding. I had
| to up my site-wide installation to 10.0 to get only the worst
| of the worst and to stop people's solicited Princeline /
| Day's Inn, etc. hotel confirmations and travel/real estate
| deals lists from getting tagged.
|
| And it doesn't help that Razor, DCC and Pyzor have a lot of
| users that report legitimate solicited commercial email as
| spam (the people that forget to uncheck "send me great
| offers" when they order a product from a vendor, and then
| report those vendors' "great offers" as spam).
|
| Maybe it's better to not use Bayes at all on a site-wide
| basis. I've noticed Columbia University doesn't use Bayes...

| I don't know if this really fits in this subject or not.
| However, I keep thinking while reading this thread if anyone
| considers real opt-in advertisements/messages that get tagged
| by SA (like from OshKosh, Travelocity, Lands' End, etc.) to
| be a FP or not. Do site-wide Bayes installs have a hard time
| differentiating without feeding?
