Is there a way to check the results of spamassassin on an email when it checks DNSBL? I see nothing in the maillog and nothing in the mail header. I do not know if it is actually querying the DNSBLs or not, which I would like to know.
I currently have spamassassin 3.3.1 setup on Centos 6.5.
You can execute spamassassin with debugging/tracking dns queries. It will track dnsbl (and dnswl) queries.
