If your ISP's DNS server doesn't know anything about your servers, it's not going to be of any help. I think it needs to answer *both* forward and reverse queries. i.e. What's the IP for the domain name (forward) & what's the domain name for the same IP (reverse). -- (This computer runs FC7, my others run FC4, FC5 & FC6, in case that's important to the thread.) Don't send private replies to my address, the mailbox is ignored. I read messages from the public lists.
