Default Zoneedit, Ispconfig and Reverse DNS.

Hi All

I have setup ispconfig on Ubuntu 11.04.

I use it mainly for Email for some of my customers.

The Ubuntu server is a Citrix VM running on a static ip 1.2.3.4.

I have full control over this server and it is also a static ip accessible from the net.

I use ZoneEdit to handle my DNS related issues.

Server was working fine untill some customers emails started bouncing.

I host multiple domains on this VM but have never had the need to setup any kind of DNS records on the ISPConfig server since I just forward it from ZoneEdit to the server.

The error the customers are getting is the following.
Connection Refused: IP Address <1.2.3.4> - HELO/EHLO Invalid or Non-Existent Reverse DNS

Obviously its a DNS issue and I would like to know what you suggest I do to resolve this. Do I handle this in Zoneedit or on the IspConfig server itself.

Thanks

Probably in Zoneedit.

Does this domain have a PTR record?
