[Mailman-Users] Could not send mail to the list

I've installed mailman 2.0.9 on Mandrake 8.1,
using Postfix as the MTA. After I created a list
called "test1" from the mailman admin webpage,
and add some members to the list, those member's
email account do receive a welcome message.
However, when I try to send a message onto my
list with the email address provided by the
welcome message (test1 at list.no-ip.org), I get a
"Undelivered Mail Returned" Message from the
"MAILER-DEAMON at list.no-ip.org" soon. The error
message is:

I'm sorry to have to inform you that the message
below could not be delivered to one or more

			The Postfix program

<test1 at list.no-ip.org>: unknown user: "test1"

What should I do? Please kindly help me.


Jesus Christ, our help for 
today, our hope for tomorrow.
