More Information About Spf Recursive Loop

This error indicates that the SPF record for the domain contains recursive issue with one or more of the "includes". One of the domains specified in the "include" tag contains a domain whose SPF record contains an "include" tag for the original domain. This creates a "loop" problem that would cause mail servers to continuously perform TXT lookups for the SPF records. As such, mail servers will end processing of SPF and return a permanent error.

If you encounter this error you will see email delivery issues to all recipient mail servers.

SPF is the cornerstone of your email delivery strategy.
