AOL has withdrawn its support for Microsoft's controversial Sender ID technology and is falling back on Sender Policy Framework (SPF), internetnews.com has learned.

"Given recent concerns expressed by the Internet Engineering Task Force (IETF), coupled with the tepid support for Sender ID in the open source community, AOL has decided to move forward with SPF," Nicholas Graham, AOL spokesperson, told internetnews.com via e-mail.

Microsoft said it had no comment on AOL's decision.

Despite the bombshell decision, the world's top ISP isn't completely severing its ties to Sender ID: The company still will publish Sender ID files so its users' e-mails are compliant with Sender ID-enabled servers and applications. But it's enough of a vote of no confidence in Microsoft's e-mail authentication strategy to warrant concern for Sender ID proponents.
