Trying to setup Reverse DNS for our domain

[EcoInstitution]

A lot of our email blasts are being bounced back to AOL email users because Reverse DNS is not setup for our IP (according to AOL's troubleshooting/error in the email header). I've done some research and apparently AOL's servers automatically reject any and all emails coming from a domain with no Reverse DNS setup.

I've poked around in the DNS management in my admin panel and I have no idea what I'm doing. Can anyone help me out? It's much appreciated. Thanks

Ask your isp to set it up. You do not have control over it.

To clarify and give more information:

DirectAdmin has a rather simplistic method for adding rDNS to your authoritative nameserver; you should run it only once for each IP# which actually is used to send mail; that's generally only the main server IP (but not always; it depends on which IP# you've set up in exim.conf for your server to send mail on) and it should point to your hostname. You may run it for other IP#s on your server as well, but that's not required for mail.

But that alone won't assure your rDNS is working. For it to work, your upstream provider (whomever you use to get your connectivity from for your server) needs to pass authority to you or your server will never be queried. And in general they don't do that unless you've got at least a /25 (class-C) allocation. Usually you just tell them what you want set up for each IP# and they do it.
