To register multiple domains at once, please use the bulk interface.
This listing is entirely a voluntary tool and only records domains submitted to it (since 15th Dec 2003); it does not represent a count of all domains using SPF.
As yet, only a count of registered domains is displayed; more analysis tools will appear once the number of domains increases.
A slight change was made to the SPF standard shortly before it was finalised; this accounts for many of the errors/warnings being seen in the early days.
Please note that the parser being used here is BETA; it is *not* the reference implementation.

To add and check your domain or server, please enter it below (repeated submissions will do no harm).
If you are logged in to the site, the domains you enter can be tagged with your email address to allow you to check them here later.
