I am getting a non deliverables from this outside servers.
The recipient could not be processed because it would violate the security policy in force
<xxxlaw.com #5.7.7 smtp;554 5.7.7 PTR invalid
I think my problem is this:
We use Exchange 2003 to send out email which is set up to go out via our Comcast line. However, our incoming email comes in from our Verizon line. There is a ptr record for our Verizon public IP but not one for Comcast which is used by the Exchange to send out. Do I need to set up another pointer record for the Comcast public IP that we send out from?
