'm having some trouble with email on a dedicated server, with Windows Server 2008. I've reached the conclusion I have to setup reverse dns for the mail server.
The current setup is this:
The mail server is an exchange server rented from a 3rd party company, and is set as MX record in our dns server. The dns server is hosted on a different machine, a dedicated server (Windows Server 2008) under my control.
The question is who needs to set the reverse dns:
- The company that hosts the email server
- Me, that controls the dns zone for the domain
- The company that hosts our name server
I've never really understood who has the authority to set the reverse dns zones.
