We just switched ISP's, and with it, we had them add routing into our own Class C subnet. This is owned by us, not the ISP.
GoDaddy hosts our domain, but with the switch we are getting some mail delivery failures due to no associated PTR record. I don't see a way of adding reverse DNS in GoDaddy (we already have an SPF record).
Does anyone have any suggestion on what I could do to remedy the mail delivery issues (554 Sending address not accepted due to spam filter) ???
