There are two versions of SPF lookups in Xeams: A debug version and a non-debug version. The debug version is designed to give details about every mechanism, and the depth is hard-coded at 20. This causes a problem when using the SPF Verify feature since the depth is set to 20.

This debug version is NOT used when emails come in. Therefore, if you run the Simulator on a message that arrives from this IP, SPF will pass.
