CircleID recently interviewed Meng Weng Wong, the lead developer of Sender Policy Framework (SPF) and founder of Pobox.com. As one of the leading anti
spam authentication schemes, SPF is used by companies such as AOL, Earthlink, SAP and supported by anti spam companies such as Sophos, Symantec,
Brightmail, IronPort, Ciphertrust, MailArmory, MailFrontier, Roaring Penguin Software, and Communigate Pro. Last month, Microsoft announced its
agreement to merge Caller ID, its own proposed anti spam authentication scheme, with SPF -- the joint standard is called 'Sender ID'.
