I am using exchange 2007, and my mx record are located in godaddy.com
when my user sent out email some of the meails get rejected, I called my isp to see if they had something to do with it, and they said no because they are not hosting the dns for the company. To call GoDaddy. I called today and they told to configure the dns section under my domain, but they could not give me instruction on how to do it. Can someone send me step by step instructions on how to configure the ptr record for my domain to point to my exchange server so the emails won't get rejected?
This is a example of an email of one of my user
