I'm new to this whole spf thing.
I have two A hosts (mail and smtp). I send mail from my domain but receive it through a 3rd party (Frontbridge a.k.a. Microsoft).
I believe the mx section below is wrong but I'm not sure. Any suggestions?
Code:
v=spf1 ip4:60.xxx.xxx.0/25 a:mail a:smtp mx:mydomain.com ~all
