E-Mail authentication fight looming: Microsoft pushing Sender ID

It looks like a fight is gearing up between Domainkeys Identified Mail (DKIM), a joint effort between Cisco, Yahoo and a number of other vendors, and Microsoft's Sender ID scheme.

An AP newswire article by Anick Jesdanun in ABC News reveals that:

Microsoft Corp. is stepping up the pressure on e-mail senders to adopt its "Sender ID" spam-fighting technology despite problems that could send up to 10 percent of legitimate messages to junk folders.

By the end of the year, Microsoft's Hotmail and MSN services will get more aggressive at rejecting mail sent through companies or service providers that do not register their domain names with the Sender ID system.
