I have two mail servers, one with only a private IP address and one with a public and private. SMTP comes in on the public address and tranfers to the server with only a private address. Outbound SMTP goes from the private server through the firewall to the destination. Now someone has configured their server to do DNS lookups before accepting mail as a spam blocking method. What entry needs to be made for the firewalls IP address' reverse lookup for mail to flow out?
