This has been covered many times in the forums, ask your ISP about your reverse DNS.Quote:

Then you're stuck without a reverse DNS. You can either change your ISP (to one that provides a reverse DNS), live with the situation or relay through another server.Quote:

Then read topic in the Admin Guide or search the wiki and forums for this topic and read the many threads/articles on the subject.Quote:

My Zimbra server connects to the virtual server using an OpenVPN link, and relays all outbound mail through that VDS.Quote:

It's not hard to set up. Zimbra setup for relaying is in the Wiki and is a piece of cake. The VDS end was not difficult either. Pretty much a base Debian install with an extra config tweak to allow relaying from the VPN subnet. The VDS provider set up the reverse for me when they configured the machine, so it all "just works".
I don't recommend or endorse the way I run things but with only 5 users and a local BESX instance it works for us.
To make any changes to your rDNS, you will need to contact your ISP or if you host your own DNS (rare) you will adjust it yourself. You will not be able to do this in your DNS control panel unless your ISP also hosts your DNS and gives you the functionality to add your own rDNS records.
