Checking Rules

[Personal Técnico]

Hi,

I would like to know how SA determines what rules are aplied while 
scanning a mail and what rules not, because I have received two mails 
with similar body but applied rules were different.

Another question: is there any way for configuring SA for getting a 
detailed score of rules in a mail when "X-Spam-Status: No". By default, 
SA does a detailed score when mail is marked as SPAM, but not in HAM cases.

Thanks.
