Microsoft Sender ID proposal

E-mail spam is here to stay, so it seems. But, many corporations and organizations are working on ideas how to stop spam.

Microsoft's latest proposal is named "Sender ID Framework", and details about it can be found from Microsoft's web site.

The Sender ID Framework (SIF) appears to be open, but the license statement is actually more limiting.

The Apache Software Foundation has raised it's eyebrows because of this, and have written an open letter to the community.

Though I appreciate the open-source community, it should also be possible for corporations to patent ideas. But, it is mostly a matter of whether a patented solution can become an IETF standard.
