Saturday, October 02, 2004Sender Policy Framework : anti-SPAM system gets OK from top ISPs
 The world's largest ISPs commit to SPF in an attempt to stop the tide of SPAM. AOL Yahoo, Earthlink, and Comcast have all signed up to making thier users adopt SPF as a self regulated means to help control the proliferation of SPAM. SMAP according to some experts now ammounts to 60% of all email transmitted on the 'net. SPF is a means by which any receiving SMTP server should be able to check that the email its being asked to accept is coming from a server that is legitimately allowed to send email for the domain in the emails 'from' part of the header. In this way 'spoofed email addresses should become a thing of the past. SPF should be relatively easy to implement, as it relies on the Internet's DNS for a large part of the process. an increasing number of email servers will support SPF today, including BorderWare MXtreme which already supports SPF and along with its exceptionally secure mail handling mechanisms should make it the email firewall of choice. One has to ask wether or not any of the major banks have implemented SPF on their mail systems. It seems not. Related Links BorderWare MXtreme SPF handling.
