 I stand corrected on this.

 The result is the equivalent.  With the only MX record pointing to the
local host, the action is to look up an A-record.  With two or more MX
records, but the best preference pointing to the localhost, you get
a configuration error message.  This still makes no sense.

 MX records with worse preference than the local host should always be
ignored.  They should not effect the way it works.

 It is still true that looking up an A-record is more useful than declaring
a configuration error, as I pointed out in message
<1990Sep21.161726.18266@mp.cs.niu.edu>.  The patch I posted on Sept 18th
achieves this effect.

  There are 26 upper case letters of the alphabet available for macros,
and most configuration files use only a small number of them.  The
lower case letters have internal predefined meanings.  Why do you have
to violate the internal predefined meaning, and cause yourself trouble
when all that is necessary is something like ':g/$w/s//$W/g' in vi?

 Sendmail 5.64 already does this in its internal definition of $w.  It
is only because it is being incorrectly redefined that you have to do
this again.
