[Rspamd-Users] Question about Bayes / Statistic

[christian]

Hello,
I have a question about Bayes. So the integrated statistical function of 
Rspamd.
What data is used for the evaluation? Only email body components or 
words that are weighted, or header components such as sender, recipient, 
Dmarc, RBL results, etc.

The standard setting for Bayes_ham and Bayes_spam is only -2 and +2, 
which, however, has a very low impact on a test. Does Bayes have an 
impact in other ways?
Thanks for info
Christian
