There are two m4 files for machines within UIUC.  Use uiuc-1.m4 if your
domain name server returns MX records for "random-host.bitnet".  This can
be done in two ways:

a) You DO NOT run your own instance of named AND your resolv.conf nameserver
entries point at {garcon,uxc,uxa}.cso.uiuc.edu (128.174.5.58, 128.174.5.50,
128.174.2.3).

b) You DO run your own instance of named AND have included the line

	forwarders	128.174.5.58 128.174.5.50 128.174.2.3

   in your named.boot file.

The second file, uiuc-2.m4, should be used by sites that have access to
pseudo-domain records as in the case of uiuc-1.m4 AND have installed
phquery as LIBDIR/phquery where LIBDIR defaults to /usr/lib/mail .
