Just to clarify: those records are in the mail.lhr.syd.com zone file,
right? The NS record is a valid delegation, as long as
"mailserver.mail.lhr.syd.com" is actually the authoritative server for
the "maildom.mail.lhr.syd.com" zone. (And as long as the IP address is
correct, of course :-)

What query, exactly, are you making? Many if not most lookup tools
assume an A record lookup if no type is explicitly given. Unless you
have an explicit A record for maildom.mail.lhr.syd.com in the zone
itself, then an A record query for that name will rightfully return
"domain not found". What happens if you do, say, an NS or an SOA query?
What does the parent master return for those queries?
