-HASSETEUID     Define this if you have seteuid(2) ***AND*** root can use
-               it to change to an arbitrary user.  This second condition
-               is not satisfied on AIX 3.x.  You may find that
-               your system has setreuid(2) or setresuid(2), in which
-               case you will also have to #define seteuid(uid) to be
-               the appropriate call.  The important thing is that you
-               have a call that will set the effective uid and NOT
-               set the real or saved uid.  Setting this improves the
-               security somewhat, since sendmail doesn't have to read
-               .forward and :include: files as root.
