[Mailman-Users] Mailman doesn't create List Owner

[Nick]

Hi,
I've installed Mailman on a debian system running postfix. I can add
newlists, and subscribe but when i go to confirm my subscription I get a
user not found (listname-request). I have created several lists but none of
the create the necessary users although the script indicates that this has
been done.

Can someone please shed some light on this problem for me
