[Mailman-Users] Help with Qmail

[Fabricio Vargas]

HI
I have  qmail with Centos 3.5, I am trying to install mailman 2.1.6,  but
when i send a mail i get this error:

Hi. This is the qmail-send program at ns.asoban.bo.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.

<lista3 at mydomain.bo>:
vdeliver: Invalid or unknown virtual user 'lista3'

I followed the guide "GNU - Mailman" and this is my configuration

in Defaults.py

DEFAULT_EMAIL_HOST = 'ns.mydomain.bo'
DEFAULT_URL_HOST = 'ns.mydomain.bo'
DEFAULT_URL_PATTERN = 'http://%s/mailman/'

in  mm_cfg.py

add_virtualhost('www.mydomain.bo','mydomain.bo')

I create the list whit this command

./newlist --urlhost=www.mydomain.bo --emailhost=mydomain.bo lista3

and add the following to /etc/aliasses

## lista3 mailing list
lista3:              "|/usr/local/mailman/mail/mailman post lista3"
lista3-admin:        "|/usr/local/mailman/mail/mailman admin lista3"
lista3-bounces:      "|/usr/local/mailman/mail/mailman bounces lista3"
lista3-confirm:      "|/usr/local/mailman/mail/mailman confirm lista3"
lista3-join:         "|/usr/local/mailman/mail/mailman join lista3"
lista3-leave:        "|/usr/local/mailman/mail/mailman leave lista3"
lista3-owner:        "|/usr/local/mailman/mail/mailman owner lista3"
lista3-request:      "|/usr/local/mailman/mail/mailman request lista3"
lista3-subscribe:    "|/usr/local/mailman/mail/mailman subscribe lista3"
lista3-unsubscribe:  "|/usr/local/mailman/mail/mailman unsubscribe lista3"

Could anyone help me to identified where is the problem?

Thank you
