Is it possible to have SA find URL in a mail and lookup the ipaddress for the URL and check if that ipaddress is listed in some rbl zone and score acordingly.
Example, I reveice lot of spam containing URL like http://www.thesillyguy.info or thenopers.info and these sites all resolve to the same ipaddress 216.40.47.17. Instead of writing rules based on these sites is it possible to write a rule based on the ipaddress ?
