Biology Lines: 20 There is a misconception here - in order for a domain to be real, it *must* be represented on the internet by a domain name server, and that domain name server must give back any resource records for that domain. In addition, if the user of that domain is not connected to the internet, that sites view of its domain and the Internet-connected server's view of that domain MUST be consistant. An example - transact.com is not connected to the Internet, but has an MX forwarder and name server named genbank.bio.net. genbank.bio.net MUST NOT reject any mail for a valid host in the transact.com domain. What my server can do is to send all mail for transact.com domain to a smart host inside that domain, and let it decide what is valid and wht is not. That way, I don't actually need to know about every host in that domain, and therefore don't need to make changes in their zone for every new host on their net. I don't consider that to be optimal but it is acceptable. -- Eliot Lear [lear@turbo.bio.net]
