  Try the following:

  nslookup
  set type=soa
  megawidget.corp

You should get back a response including a mail address.  It will be
in a funny form.  If it looks like:  HOSTMASTER.Boss.MegaWidget.Corp
it is referring to the address 'HOSTMASTER@Boss.MegaWidget.Corp'.

This is actually the address of the person who maintains the database
for the company.  May not be the postmaster.  But you could try
'Postmaster@Boss.MegaWidget.Corp' as a likely postmaster address.
