American Online Inc., announced that it will not adopt Microsoft's SenderID protocol because Internet engineers do not want to adopt a non-open source software. Several proposals by Microsoft and others would allow Internet providers to check that a message actually comes from sender's server computers. Messages that do not match up could be safely rejected as spam.
"AOL will now not be moving forward with full deployment of the SenderID protocol," says, AOL spokesman Nicholas Graham.
AOL said they won't use the standard because Microsoft holds patents on the underlying technology, reported Reuters.
