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."

    So what? Microsoft is working on a new secret email technology and they need people to test it. They are paying people for it too! Send this email message to 10 people and receive a check for $50.00 from Microsoft. My friend Tom did it and it really works!
