And? It does not matter. Postfix like any other MTA does A and MX record lookup from DNS, it does not care about whois, etc. Also you can put even xxx.yyy.zzz.www.domain.tld into your domain, of course there will be no "whois" information for that. It's even possible that you have a domain but no A nor MX records for a given name, also you can have some "private" DNS zones, split-DNS config etc etc. Since MTAs using DNS to look up things you should do that as well to debug mail problems. It's also possible that there are "registration details" but the domain "does not work" (none of the authoritative DNS servers responds, other problem etc). I really don't understand why you'd like to force this whois thing here ... It won't help you to solve this problem ... -- - Gábor
