That little gotcha isn't documented as clearly as it probably
should be....  The "w" macro in sendmail.cf must be set to your
site's full official internet name (which is also the name that
appears on the MX records).  If "hostname" on your machine
returns something other than the fully-domain-qualified official
hostname, you'll have to explicitly set the "w" macro to be the
official name.
