If you only need reverse DNS set up for a single IP address, the best thing is to email the ISP and ask for a "PTR record to be set up for the IP address you gave me of 1.2.3.4 to point to mail.example.com". If you want your ISP to delegate reverse DNS to another DNS server out of their control, you're going to find it very difficult to get them to do it. The only time typically an ISP will be willing to do it is if you are on a T1, T3 or other high-end dedicated circuit, or if you are on business-grade DSL service where they have assigned you a /28 subnet or higher. If the latter is what you are trying to do, ask them to "delegate reverse DNS for 1.2.3.4/28 to ns1.example.com and ns2.example.com". The key word to use here is "delegate reverse DNS", as opposed to the generic term of "point reverse DNS", which could be taken as either method. -- Dean Brooks [EMAIL PROTECTED] -- ## List details at http://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
