Re: BAYES_00 BODY. Negative score?

2023-02-18 Thread hg user
please
spamassassin -D bayes -t file.eml 2>/tmp/z
and in /tmp/z you will have the score assigned to the "tokens"... from
those points you will understand what created the different totals.

If you can you may relearn all the messages, both ham and spam, with the
tip suggested a couple of days ago, removing all the headers. It may lower
points to some spam but probably it's better..

This looks like you have per-user Bayes databases, and the messaage type 
has been trained differently in each.


Also, it looks like there are per-user rules, since BAYES_50 has a 
normal score of 0.2, and there is no reason BAYES_20 (indicating much 
less spammy) should have a score of 2.2.




Per-user is not setup.

This morning I sent the message again, with users reversed in the TO: 
field and the scores are identical.  This may prove nothing as I 
thoughtlessly added the high score message to my "HAM" folder and it was 
processed.


While the scores are identical the X-Spam-Report lists them in different 
order, while X-Spam-Status shows them identically, "RCVD_IN_MSPIKE_H2 
RBL" being listed near the top in one and near the bottom in the other.


Perhaps that is meaningless, but it pings my curiosity.

They receive wildly different BAYES scores.


as was mentioned, they were apparently tested under different user.

I want to add, that multiple similar messages can have invisible differences 
which can result into different BAYES results.


Just this week I noticed (at least) two phishing waves, training one e-mail 
resulted into pushing other e-mails' scores up to BAYES_999, while other 
still had BAYES_50 or BAYES_80.


Simply, we need more training.

if needed, scan the same mail under different user, if possible.
