[Mailman-Users] New Mailman Installation - Can't Send Email to a New List

[mcjathan]

Greetings,

We've recently installed Mailman 2.1.9 on our server. We have installed 
and configured Mailman in a postfix environment that is using mysql (See 
our server configuration at the bottom of this email).  We can create a 
new list, log onto the admin and user web interface.  However, we are 
unable to send email to a newly created list.  When we try to send an 
email, the send process hangs with the following message:

    Alert

    An error occurred while sending mail.  The mail server responded:
    <testlist at ourserver.com>: Recipient address rejected: User unknown
    in the local recipient table.  Please verify that your email address
    is correct in your Mail preference and try again.

We've followed the instructions in the pages below and still been unable 
to fix the problem:

    http://www.python.org/cgi-bin/faqw-mm.py?req=show&file=faq03.014.htp

We've noticed that the .../data/virtual-mailman.db does not populate.  
Running genaliases populates the .../data/aliases and 
...../data/aliases.db.  Adding a new list updates the aliases.db, but in 
either case, the virtual-mailman and virtual-mailman.db files have no data.

Questions:

1) Is our inability to send email to the lists due to the fact that the 
virtual db files aren't being populated?
2) If so, how do we fix this for our already created lists?
3) If so, how do we fix things so that lists we create from now on don't 
have this problem?

Regards,  Jeff
