How will rival authentication schemes change the way we communicate online?
Microsoft's recent announcement of a host of initiatives to stop unsolicited commercial e-mail, or spam, highlighted some tectonic shifts taking place in the once staid world of Internet messaging. The company's announcement was made at the RSA Conference, a leading annual meeting on electronic data security that was held in San Francisco late last month.

Caller ID

The company's new e-mail authentication architecture, known as "Caller ID," is being met with cautious acceptance. However, Microsoft will probably not have the last word on secure e-mail, and a shakeout of different antispam solutions backed by Microsoft, Yahoo, America Online, and others is likely in coming months, experts warn.

Microsoft used a keynote address at the RSA Conference by Chair and Chief Software Architect Bill Gates to unveil its new authentication scheme. With Caller ID, e-mail senders publish the IP address of their outgoing e-mail servers as part of an XML format e-mail "policy" in the Domain Name System record for their domain. E-mail servers and clients that receive messages can then query that DNS record and match the source IP address of the message to the address of the approved sending servers. E-mail messages that don't match the source address can be discarded, Microsoft said.
