Reverse DNS SBS 2003 One More Time Please
Hello All,
I have a SBS 2003 network and apparently I need to set up reverse DNS. I have read many of the past posts, and would like a little more clarification for my situation. Here is my schema.
SBS 2003 standard, Exchange FQDN when I telnet is “company.com,” Public DNS MX record is “mail.company.com” (do these need to be the same and how do I make the change on the server if necessary?), ISP is Time Warner, DNS set up by me through ixwebhost.com, I have a single static IP address that resolves to my server, the is a “company.com” website with a different IP address.
Please provide instructions on how I should implement reverse DNS and in what order I should make changes. I am familiar with SBS and DNS and understand the concept behind reverse DNS, but would like specific instructions on what to do.
Thank you all very much for reading this post and for your help. Please do not just post a couple URLs, I would really appreciate some instructions. Thank you again for your time. eric

Thank you for your tests and instructions. I ran the test and it said "Warning - Reverse DNS does not match SMTP Banner" so I followed the instructions and changed the banner name. I ran the tool again and received the same error, however it seemed to have recognized the change in the name. I tried it several times and double checked. The url is leisure-lift.com and you will find that the mail server is mail.leisure-lift.com would you please try it yourself and see if you can come up with an explanation.
If you don't have reverse DNS set up yet it would also show as different.

when I telnet to my server on port 25 it answers as "company.com" not "mail.company.com" is this an issue?
