Complicated SMTP DNS reverse lookup zone
I want email sent from my server on behalf of a client to pass a reverse lookup test.
I operate a website for a client. This website sends acknowledgement emails. My system is completely separate from my client; this is an arms length business arrangement. The IP for my webserver outside of the client's IP block.
The Client domain is "my_client.com". They, the client, created a subdomain "houston.my_client.com" which is pointed to my IP. The website is "www.houston.my_client.com". My router sends all traffic for the IP to this web server, an external IP to internal IP translation.
I generate emails from "john.doe@my_domain.com" using the smtp service in this server. People receiving these emails must be able to resolve them as legitimate and linked back to my_client.com.
My webserver is 2008 R2 x64. My webserver is not the DNS server on my network. DNS service is not installed/enabled on the webserver. ( I have a 2008 SBS as the Active Domain Controller, and it is the DNS for my LAN.)
What do I do, if anything, to have the email receiving system resolve that mail from my server as legitimate email from my_client.com? I have never been walked through setting up a simple DNS reverse lookup zone. Do I install DNS on this box? If so, then what?
Thank you for reading this. I hope you can help me.

I understand your problem with reverse DNS is related a public IP address. If you are responsive of your reverse DNS, you must to create your own ptr resource, otherwise, ask your ISP (because your ISP has a reverse DNS of every IP) to change PTR same as resolve DNS direct query.

Can you tell me what the form of my own "ptr resource" would look like?
Assume this:
The client's public domain is "my_client.com" and the IP is 111.111.111.001
My public IP is 222.222.222.001
The client points to me for "houston.my_client.com"
Can you give me the example ptr resource string?
