Reverse DNS Entries for MX Records

[FoxHosting]

Hello.

Have Virtuozzo Power Panel and Plesk 7.5.1on Windows2k3 and have set up test client and domain. It runs Mail Enable V1.8.

DNS check produces the following error regarding the reverse DNS entry for the mailserver:

<<ERROR: The IP of one or more of your mail server(s) have no reverse DNS (PTR) entries (if you see "Timeout" below, it may mean that your DNS servers did not respond fast enough). RFC1912 2.1 says you should have a reverse DNS for all your mail servers. It is strongly urged that you have them, as many mailservers will not accept mail from mailservers with no reverse DNS entry. You can double-check using the 'Reverse DNS Lookup' tool at the DNSstuff site (it contacts your servers in real time; the reverse DNS lookups in the DNS report use our local caching DNS server). The problem MX records are:
xxx.xxx.xxx.xxx.in-addr.arpa [No reverse DNS entry (rcode: 3 ancount: 0) (check it)]>>

How do I add the reverse DNS (PTR) record to remove this error, thanks.

Kindest regards

Have you found a resolution for this yet?

I assume you use your Plesk DNS server as preferred. Go to the PleskCP->Server->DNS and check is there any PTR record type, if there is no such record, add one
If you use external DNS servers, ask admin to update reverse lookup zone with ptr records of domains you host on Plesk server

sometimes it is not enough to add a PTR record cos the rdns is not delegated to your server, but your uplinks handles the rdns.

check http://www.dnsstuff.com/ option Reverse DNS lookup , to see if your server is the one who handles the rdns

He needs to make those operations on primary dns servers which are registered to be authoritative for zone (e.g in registrant database)
