Hi, I have searched your website, but cannot find what I require. A fair bit of mail is bouncing from our servers as we do not have a PTR record setup. Most of the google searching I have done (and your website) says that your ISP sets this up for you. We are hosting our own Virtualmin server (with four IP addresses). It is used as a web and email server for multiple domains. Do you have a quick 'how to' on setting up a PTR record on the virtualmin server please? I have been meaning to do this for a while, but is seems more and more now mail is rejecting because this entry is expected.
