Hello everybody!
   I just installed Mailman version: 2.1.15  in a Centos server running 
Postfix 2,11,3

  I had create a list ( cod3 at listas.pccorreo.com.ar ), and everything 
went right.

But when I send a message to this list it appears some errors:

<cod3 at listas.pccorreo.com.ar>: Command died with status 5:
     "/usr/lib/mailman/mail/mailman". Command output: Usage:
     /usr/lib/mailman/mail/mailman program [args...]

<post at listas.pccorreo.com.ar> (expanded from 
<cod3 at listas.pccorreo.com.ar>):
     unknown user: "post"

<cod3 at listas.pccorreo.com.ar>: unknown user: "cod3"

What do you think about??

Thanks in advance, Alberto
