MailEnable Standard Guide
To set up PTR records under Microsoft's DNS Server
  1. Ensure that DNS Forwarding is enabled on the server. This means that if a client cannot find DNS records on the mail server, the DNS server will forward request to your ISPs DNS servers. This can be accessed under the properties of the server - Forwarders Tab (within DNS Manager)
  2. Create the Reverse Lookup Zone for address range of the public IP address (e.g.: 201.248.10.* ). Create this by selecting 'New Zone' under the properties of the server (within DNS Manager).
  3. Create PTR Records for all of the IPs under the Zone outlined above (within DNS Manager).
  4. Ensure the primary DNS IP addresses used by MailEnable's SMTP Connector is configured to use the local DNS rather than referring upstream to your ISPs. This is much faster and more efficient. (This is done via the MailEnable Administration program under the properties of the SMTP Connector)
  5. Restart the SMTP Service to place DNS Server changes into effect (Service Control Manager)
Note: Check with your ISP that they allow PTR referrals to your server. This can be checked using resources at http://www.dnsstuff.com
