Or you could just set an entry like
10.21.23.20 mail.yourdomain.org
on every client machine (/etc/hosts or
%windir%\system32\drivers\etc\hosts (could be different for win2k)).
You could set that up using a logon script (active directory or
samba, doesn't matter), or by tricking users with candy to run the
script manually :)
