Microsoft and Yahoo! Fight Spam - Sort Of
kyndig writes "In a Forbes article, Microsoft claims that 90% of
email on the internet is spam. To fight this, Yahoo! has teamed
with Cisco in developing DKIM, a signature based email
authentication. Not to be outdone, Microsoft is proposing
SenderID, which examines an email to see if it is coming from an
authorized server. Earthlink's chief technology officer, Tripp
Cox, goes on to examine the pro's and con's of each specification
and provides practical application results." From the article:
"Critics have accused Microsoft forcing SenderID on the industry
without addressing questions about perceived shortcomings. The
company drew fresh criticism recently when reports claimed that
its Hotmail service would delete all messages without a valid
SenderID record beginning in November. While AOL uses SPF, many
e-mail systems do not. If Microsoft went through with this, for
example, a significant portion of valid e-mails would never reach
intended Hotmail recipients."
