SPF is an open standard.

As a product of the best traditions of opensource development, SPF can be implemented and deployed entirely on your own, without having to sign any licenses or pay anyone anything.

Over 1.7 million domains have published SPF records (as of November 2005). Many of them have done so with a help of this wizard.

If you lack the mojo to do it on your own, you can borrow some of ours. Don't worry, we have plenty.

The SPF community has partnered with many leading providers of consulting services to meet your needs. Available services include:

• Education and planning
• Publishing SPF records
• Stray user detection
• Problem case elimination
• Ongoing testing and validation
• Statistics gathering
• Strategic strategizing

There are several mailing lists that are available to help answer questions and discuss issues with SPF. We encourage you to join and participate in the SPF community!
