I have an Exchange 2010 mail server hosting all roles. Its used for sending and receiving emails into our domain.
I noticed some delivery queues in recent times to yahoo, hotmail, gmail and other SMTP domains. I therefore run the ExRCA on the server.
I noticed some errors, for SPF and also the PTR record sections.
After some research I have successfully created the SPF record using the command v=spf1 mx -all in the TXT record. Everything seems okay now for SPF.
How do I create the PTR record for my NATed public exchange server address?
Do I need to contact my ISP or create this locally on my local DNS server.
The error I receive is as follows:
Performing Outbound SMTP Test
The outbound SMTP test failed.
Attempting reverse DNS lookup for IP address 22.214.171.124, (generic public IP).
Reverse DNS lookup failed.
IP address 126.96.36.199 doesn’t have a PTR record in DNS.
