Actually, I was reading this when I thought of it, and thinking of how INVURIBL reads the links
inside of an e-mail and then compares them to a configured RBL, like the recommended Invaluement paid subscription. http://www.blue-quartz.com/rbl/ It would be much more efficient to store large numbers of IPs in DNS than it would a plain text blacklist, wouldn't it - or am I wrong about that? This is the relevant quote from this page: If a blacklisted IP address is in your rbl database it will "exist" in the DNS system. For example: if you blacklisted IP 89.40.1.32 then doing a regular DNS lookup like this: nslookup test.rbl.mydomain.com nslookup 32.1.40.89.rbl.mydomain.com should result in a match of 127.0.0.2 I haven't figured out how to get the e-mail harvesting IP blocks out of SmarterMail yet, but if I could, then if I could script-insert them into DNS and then use that as a local RBL, do you think that would be an effective tool? Those are the spammers that are banging on my door, right? -- Michael Cummins -----Original Message----- From: supp...@declude.com [mailto:supp...@declude.com] On Behalf Of Sanford Whiteman Sent: Saturday, July 11, 2009 3:09 AM To: Michael Cummins Subject: Re[2]: [Declude.JunkMail] Cutting down on DNS > Probably a crazy question, but if I wrote a script to harvest the current > blocks (for e-mail harvesting) out of SmarterMail (if such a thing could be > done) would that make a good or a bad local URI? Are you talking about turning a list of IPs into a list of dotted-decimal URIs like http://1.2.3.4 ? That doesn't make sense. --Sandy ------------------------------------ Sanford Whiteman, Chief Technologist Broadleaf Systems, a division of Cypress Integrated Systems, Inc. e-mail: sa...@cypressintegrated.com SpamAssassin plugs into Declude! http://www.imprimia.com/products/software/freeutils/SPAMC32/download/release / Defuse Dictionary Attacks: Turn Exchange or IMail mailboxes into IMail Aliases! http://www.imprimia.com/products/software/freeutils/exchange2aliases/downloa d/release/ http://www.imprimia.com/products/software/freeutils/ldap2aliases/download/re lease/ --- This E-mail came from the Declude.JunkMail mailing list.
