Sender ID licence opened up

Microsoft frees up access to anti-spam framework.

Microsoft

has put the specifications for the

Sender ID

and

Sender Policy Framework

(SPF) email verification system under its ‘

Open Specification Promise

‘ (OSP), allowing open-source and other projects to integrate the framework without charge or hinderance.

The

Sender ID

system ties email addresses to IP addresses, in an attempt to prevent spammers and phishers from spoofing sender details. The system is currently used by a variety of mail filtering systems, but under the new scheme will be available to a broader range of developers and products.

Rather than being a fully open licence, the OSP is essentially a promise not to sue anyone for using the technology covered. The OSP homepage, with a full list of technologies released under the system, is
