[Mailman-Users] Trouble Creating List Owners

[Nick Cockinos]

Hi,
Thnaks to those who helped eralier. Your suggestions helped get the list owner 
aliases into the /etc/aliases file.

I'm still having trouble understanding this though. When I create a list 
(./newlist -o /etc/aliases new_list) aliases ar created as follows:

new_list "|/home/mailman/mail/wrapper post new_list" 
new_list-admin "|/home/mailman/mail/wrapper mailowner new_list" 
new_list-request "|/home/mailman/mail/wrapper mailcmd new_list" 
new_list-owner new_list-admin 

Should the user new_list-admin be created locally or can it be any valid email 
address? I have added new_list-admin which accepts mail ok, but what about 
new_list-request and new_list? 
Should these be added manually? 
Should they be created when the list is created?
Is there something I have to reconfigure woth wrapper to get this working?

My system is Debian 4.5 and Postfix version unknown

Thanks in advance for your help and patience
