We just got bit by this -- a user tried to send mail to a FQDN in the
"HK" (Hong Kong) domain; we didn't have an up-to-date top-level domain
list and thought it was an unqualified name....

The latest list of top-level domains can be retreived by anonymous ftp
from nic.ddn.mil in netinfo:domains.txt.  Here's the one I fetched
yesterday:

; [SRI-NIC] NETINFO:DOMAINS.TXT		     19-Aug-90
;
; Only top-level domains are listed.  Information about subdomains
; should be acquired by asking the top-level domain servers.
;
; Format of entries conforms to that of NETINFO:HOSTS.TXT (RFC952).
; !!NOTE!! this is not the same as the original format!!
;
;	DOMAIN: <addresses> : <name> : [possible extra fields]
;
; The addresses given are those of Internet hosts which provide
; a Domain Name Server for that domain.
