Silverpop implements e-mail authentication mechanism

Published on .

Atlanta--Silverpop, an e-mail marketing company, announced Friday it has implemented Sender Policy Framework (SPF), an authentication mechanism, for its clients.

Authentication mechanisms prevent spammers from falsifying their identities.

AOL is among the companies currently supporting SPF, which is an open source solution. It works by checking Domain Name System servers against the IP address of incoming messages in order to separate spam from legitimate e-mail.

Other authentication mechanisms that have been developed include Yahoo!'s DomainKeys and Microsoft's Caller ID.
