	Greetings sendmail wizards, I realy need some help regarding sendmail.
I am in charge of a small group of NeXTs (about 30) here plus 1 NeXT cube. 
This cube is our NetInfo, NFS, and Mail server.  We have an MX record for each 
of our clients to point to our server, and another MX record called "csld" that
also points to our server.  MY problem is this:

	Whenever you send mail from a client TO a client or anywhere TO a
client we would get an Internal Mail Loop error.  For example, say I was on
a machine outside our network called "ucrengr", and I tried to send mail to
the client "page", I would get the following error.

Return-Path: <Mailer-Agent@mozart>
Date: Tue, 10 Nov 92 15:42:44 -0800
Subject: Returned mail: Service unavailable
To: osiris@ucrengr.ucr.edu

   ----- Transcript of session follows -----
While connected to mozart.UCR.EDU:
>>> HELO CSLD.ucr.edu
<<< 553 CSLD.ucr.edu config error: mail loops back to myself
554 <testy@page.ucr.edu>... 554 Service unavailable

   ----- Unsent message follows -----

<STUFF DELETED> 

Of course, the server runs fine.  Any ideas how to fix this?  I have NO 
IDEA what to do in Sendmail.  Please reply via E-mail, and thanks in advance!
