>From the Sendmail documentation:

     5.3.3  Error messages are sent as  From:<>.   This  was

             urged  by  RFC  821 and reiterated by RFC 1123,

             but older versions of sendmail never really did

             it  properly.   Version  8 does.  However, some

             systems  cannot  handle  this  perfectly  legal

             address; if necessary, you can create a special

             mailer that uses the `g' flag to disable this.

It sounds like the current configuration for Sendmail is right and Taylor is
broken.  I have not looked at this myself, however....
