should I change score for Bayes_90?

I too have adjusted my Bayes scores. Here they are.

score BAYES_70 0 0 5.593 3.310
score BAYES_80 0 0 5.300 3.862
score BAYES_90 0 0 4.900 4.200
score BAYES_99 0 0 5.200 4.900

auto_learn 1
auto_learn_threshold_spam 10
auto_learn_threshold_nonspam -3.0

Hopefully I got those correct. I receive nearly 90% spam on the accounts
affected by this mails server (some of the addresses were used for newsgroup
postings as far back as 94). I know I have everything set really low but it
works for me. Spam threshold is 5, Bounce is set to 7. I have gotten only
one false positive in the last few months (I monitor the subject and authors
of bounced messages using MailWatch).

Nobody responded to the thread (exept you). I analyzed a bunch of spam and
decided to change the scores myself. I arbitrarily decided to set Bayes_90
4.25 and Bayes_99 to 4.50. So far, it seems to be working well.
