I am using SA 3.2.3 and very few spam get thru But I can still see some spam with urls because the the urls are not yet listed in uribls
I tried to do some analysis on my quarantine, I found atleast some spammer domains have the same NS records. Now in my spamassassin can I do a DNS check (on all domains in body-urls or mail-from, reply-to etc) to find their NS records and score them on bad NS servers. What is the risk of FP's because innocent DNS providers may see themselves getting list Thanks Ram
