   The other new behavior is that I get messages like:
	   SYSERR: rewrite: cannot prescan canonical hostname: 
   With no hostname following it...  Any ideas?  Should I be concerned about
   these?  This happens a couple of times per day also.  The messages for which
   this happens stick around in the queue, with lock files still existing, so
   I'm sure there's really something wrong on this one.

As far as I can tell this happens when a host puts its CNAME name and not
a name with an A or MX record into the SMTP FROM header.  In one case
this little exchanged caused sendmail to core dump (Sun 4/260, SunOS 4.0.3,
sendmail.mx from uunet).

Be liberal in what you accept, I guess, but not in this case.
