Mail Problem

[Marc Friedman]

	A few days ago I posted a message about a problem after 
upgrading to Elm 2.3 PL11, in which my aliases were no longer 
recognized by elm.  Well I resolved that problem by deleting all
my alias information and re-creating it.  Well now I have found 
a new problem with the mailer on my system, I'm not sure if it's
related to the Elm upgrade or mere coincidence.  Now whenever
mail is sent to this machine (hostname: rainbow), I get the
following returned mail:

 
From: MAILER-DAEMON at rainbow.mitre.org (Mail Delivery Subsystem)
Subject: Returned mail: Service unavailable
Message-Id: <9104251211.AA01660 at rainbow>
To: <marc at eddie.ee.vt.edu>
Status: RO

*** Stuff deleted ***

	Does anyone have any ideas??  Everything has been working
fine for about a year and the only mail related thing I've changed
is Elm. 

Thank you very much in advance.
