Exchange 2010 RDNS fails but ISP has added the correct record

Hi Guys

I am getting an RDNS failure for my Exchange server when I run mxtoolbox RDNS lookup. It's telling me that the SMTP banner does not match the RDNS record.

My setup is:
- Domain host: A mail record for domain1.com points to our static IP where the Exchange server is hosted. MX record points to A record for domain1.com
- ISP: RDNS record from our static IP points to mail.domain1.com
- Exchange: send and receive connector FQDN is set to mail.domain1.com as per http://community.mxtoolbox.com/forums/viewtopic.php?f=6&t=13143

We are getting bounces back quite a bit for yahoo senders so I figure this might be the cause.

What have I got configured wrong for our RDNS?

Kind Regards
Aaron

You have two options:

1 Change the PTR pointer to the name of the server.

2 Rename the server to what the PTR is.

I think I found the issue. The PTR record set by the ISP is the users link user.lnk.telstra.net and not the correct address. I've just asked them to change it :)
