SUMMARY
How to set up PTR records under Microsoft's DNS Server.
DETAIL
1. Ensure that DNS Forwarding is enabled on the server. This means that if a
client cannot find DNS records in the 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 Reverse Lookup Zone
for address range of your public IP address (e.g. 201.248.10.*). This is created by
selecting new Zone under the properties of the server (within DNS
Manager).
3. Create PTR Records for all your IPs under the Zone outlined
above (within DNS Manager).
4. Ensure the primary DNS IP addresses
used by MailEnable's SMTP Connector to use your local DNS rather than
referring upstream to your ISPs. This is much faster and efficient. (This is done
via MailEnable Administration Program, under the properties of the SMTP Connector)
5. Restart
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. Most ISP's do. This can be checked using resources at
