[Mailman-Users] Aliases not working

[Joshua]

Mailmen -

I just upgraded to b9.  Running Sparc/Linux on a SS4 with RH 5.2.  
Got things working ok - almost.

I created a test list 'test3' and the admin, info work ok.  I can't tell if 
list_members does cause I haven't been able to subscribe to the 
list.  

these email addresses:

test3-request at brassica.agronomy.wisc.edu
test3 at brassica.agronomy.wisc.edu

return:

From:  Mail Delivery Subsystem <Mailer-daemon at brassica.agronomy.wisc.edu>
Subject:        	Returned mail: User unknown

However, the confimation of request was formatted correctly:
From:           	test3-request at brassica.agronomy.wisc.edu
Date sent:      	Sat, 20 Mar 1999 00:26:21 -0600
Subject:        	Test3 -- confirmation of subscription -- request 357936
To:             	jaudall at students.wisc.edu
Send reply to:  	test3-request at brassica.agronomy.wisc.edu

I didn't think there needed to be 'hard' aliases for these addresses - 
Though I don't know how mailman does it - but, the method is not 
working.

Note:
The aliases put into /etc/sendmail.cf work fine.  (i.e. mailman-
owner at brassica.agronomy.wisc.edu)

Any suggestions?  I could use some help.
