Hello\n\nThis might be a dumb question so please bear with me!\n\nJust started at a new company and need to get my head round reverse DNS for\nExchange. Currently it is not setup and many emails fail.\n\nThe company hosts it's own DNS servers for the domain. The domain (the\npublic xxxx.org) is at the ISP but the nameservers are here and I have\ncontrol of them. The ISP has simply pointed the nameserver records to\nservers here.\n\nI don't have a lot of DNS experience but get by.\n\nCan anyone offer any advice and steps to follow to setup a reverse DNS for\nmy mailserver please. I assume since we host the DNS that we need that\nhere?\n\nIn the past I have always had DNS for the domain name hosted at the ISP so\nthey made any changes like this, so this is new to me.\n\nThank you in advance.
