If you run a DNSReport on StriveGreen.com you will get the following:
The SPF value does not allow mail delivery from all mailservers in the domain. This may cause problems if you use the same servers for incoming and outgoing mail. The failing mailservers are:
domain of strivegreen.com does not designate 98.129.185.131 as permitted sender | fail | 98.129.185.131
domain of strivegreen.com does not designate 173.203.2.32 as permitted sender | fail | 173.203.2.32
However, if you run the separate SPF test using 98.129.185.131 and postmaster@strivegreen.com you get a PASS.
What gives????
