Are you attempting to send this mail when using a non-Cox IP address/connection? I have seen this type of error usually occur when attempting to send email from an IP address that does not support SPF as that error code indicates. You may want to trying sending when connected to a different connection or home internet connection when possible. Make sure there are no VPN's or anything of that nature turned on either as that can cause this as well.

Nope. I'm using my Cox email... through my Cox router.
