[Mailman-Users] test list problems

[Omar Armas Aleman]

I installed mailman-2.0beta2 in RH6.2, and created "test" list, I can see
the web page of the list and added a few members, but when I send a mail
to the list, I don't receive anything. 
This is what I see en /var/log/maillog:

How can I fix it?

This is are the permisions of the wrapper:
[oarmas at linux src]$ ls -l /home/mailman/mail/wrapper 
-rwxr-sr-x    1 root     mailman     30891 Apr 25 18:37 
/home/mailman/mail/wrapper
[oarmas at linux src]$ 


I "did" newaliases and have the correct alias in  /etc/aliases.

Please help me.
