I have been trying for a few days to add to the tests that spamassassin does (which scores individually, and if the total score exceeds a certain value, then it is labeled as SPAM) that checks if the originating IP of the email appears in certain new blacklists, but I think that spamassassin It does not run those tests that I add.
The option of adding them to the postfix does not work for us because there it is 'yes or no', and what we want is to 'add points' in the spamassassin, and thus if it comes out positive in several tests, we will know for sure that it is spam.
Is there a possibility that spamassassin can do these tests (dnsbl) by adding servers by hand?
