Sender Policy Framework

Sender Policy Framework (SPF) is an attempt to control forged e-mail.  SPF is not directly about stopping spam – junk email. It is about giving domain owners a way to say which mail sources are legitimate for their domain and which ones aren't.  While not all spam is forged, virtually all forgeries are spam.  SPF is not anti-spam in the same way that flour is not food.

SPF is a protocol developed by a group of motivated volunteers, joined by a mutual desire to improve the operation of the internet. It is NOT a commercial product offered by a for-profit corporation. The SPF protocol is being adopted by a growing number of domain hosts and Internet Service Providers (ISPs), and, as in any technology evolution, there will be some bumps on the road. While the people behind this website and the people who have helped develop SPF may be able to help you understand how to solve problems when they arise, they are not responsible for the problems you may be experiencing.
