I'ts better to use a foreign nameserver, for instance your uplink/isp, or a friendly nameserver somewhere else. I use a perlscript with Big Brother, giving yellow alert when my nameserver disagrees with a foreign nameserver, and I know something is being redelegated. I have a # comment with the date in resolv.conf. Then when the change is finished, I change the # to a // comment. I get a red alert when my nameserver(s) disagrees with the foreign nameserver, and I haven't a # comment, i.e. the change is not supposed to happen. Btw, I _never_ delete a domain from resolv.conf, I just comment it out, with a date and reason, to keep the history somewhere. Another BigBrother script checks if the domains in sendmail.cw, also has the mailserver as lowest MX. Leifhome | help
