[Mailman-Users] Join List Problem

[Bill Honneus (honneus)]

Hi,
 
I have my mailman set up and configured on my sendmail server as per the
instructions in the Mailman Installation Manual.  I was able to create a
list called "test" using the newlist command line option, and got a
confirmation email at the list owner's address.  I have defined the
aliases for test in my mailman.aliases file in /etc, separate from my
aliases declarations.  When I send an email to test-join at my.domain.com,
I get the following returned email error:

I don't understand why it says it can't find the "test" list as my
apache server finds it just fine via the web browser, and I see the
"test" appear in the "lists" folder underneath /usr/local/mailman.
 
Anyone encounter this issue before?
 
Thanks,
 
Bill
