The nslookup is pointing directly at our internal DNS server, which is
definitely configured to do recursive queries (i.e., "smart" lookups). It
does work for 98% of the Internet. For about 2% of all hosts it is
failing, and that is impacting service of the mail server, so it's a serious
thing I need to get fixed.
