(Hello again)

Here's a problem we're really stuck on... this is sendmail 5.61 as
distributed with Interactive Unix V2.2 (System V 3.2).  The sendmail.cf
file is happy as a clam.  It decides that addresses on machines on our
local network should be sent with mailer "ether", defined as:
  Mether,         P=[IPC], F=emsuCDFLMX, S=11, R=21, A=IPC $h
However, the log reveals that sendmail thinks that the host is "unknown":
Apr  5 15:55:29 localhost sendmail[200]: AA00198: to=erf@xyzzy,
		delay=00:00:00, stat=Host unknown

But: host xyzzy is in /etc/hosts, we have NO nameserver running,
/etc/resolv.conf contains the single word "nonameserver", tcp-ish commands
like "ping", "rcp" and "rlogin" all understand and can connect to
host xyzzy, as well as all other hosts in the hosts file.  We've
restarted the sendmail daemon, re-frozen the configuration file, and
even offered a burnt sacrifice, but nothing seems to help.  I should also
add that the configuration file detects local hosts properly, so that
erf@xyzzy uses the "ether" mailer but erf@unknown_host gets sent to a
gateway machine.

Can anyone out there help us???  This is getting very frustrating, and we're
about to hard all sharp objects in the area so we don't hurt ourselves.

Please E-MAIL any replies to: ericf@zurich.ai.mit.edu

Thanks in advance for any and all help!
