AOL Tests Sender Permitted From / E-mail Caller ID

Posted by timothy on from the spammers-need-some-heavy-suin' dept.

securitas writes "ZDNet reports that AOL is testing Sender Permitted From (SPF), 'an antispam filter intended to accurately trace the origin of e-mail messages.' AOL is performing the widescale SPF test with its 33 million subscribers worldwide. The system works by letting recipients use the SPF record to cross-check DNS data associated with AOL's IP addresses and confirm that the message originated from AOL's servers. The system is one of three competing e-mail authentication protocols. The other IP-identifying protocols are the Designated Mailers Protocol (DMP) and Reverse Mail Exchange (RME/RMX). All systems alter the DNS database to let e-mail servers publish the IP addresses that they use to send e-mail."

    Well, I guess I'll just go on being the only person who must not get spam.

    And, I reckon I'll not post any more honest questions in a /. forum. Bastids.

  2. I don't accept mail from AOL anyway by Anonymous Coward · · Score: 0, Flamebait

    I've seen 0 legitimate emails from AOL since they started, 100% spam. If this technology proves it comes from an AOL server so what? Its just more spam but confirmed to come from AOL.

    Big deal ;(

    Still won't get it. I can hit delete faster than I can get annoyed at doing it. That NOSPAM is there 'cause I'm relatively lazy and didn't uncheck the box.

    I have yet to RTFA, but how could I implement this into my SMTP server (Postfix)?
