Q: This documentation doesn't seem to cover how to configure DNS-Blocklists. It says "Support for these is built-in" but I can't believe that all free BL's is called each time a mail is beeing checked. There must be a way to configure which to use.
A: You're right. You might look at the Mail::SpamAssassin::Conf documentation page which I admit doesn't really say how to configure which DNSBL to use, or the rules file 20_dnsbl_tests.cf, for internal details, but no clear examples of how to configure the inclusion of various DNSBLs either. For the latest list of DNSBLs you want to be using a recent SpamAssassin version (3.24.x 1 at the time of this correction) and sa-update, for the same reason that you wouldn't use an out-of-date virus scanner, but that also doesn't really have anything to do with the question.
