[Mailman-Users] New install problem

[John Lieber]

I've got a fresh new install on an Ubuntu Server 8, Mailman version
2.1.9 (installed from apt). Agent is Postfix

 

I have the list installed and appears to be running.  Mail sent to the
list shows up in the archive.  However the members are not receiving any
mail from the lists.  Checked the spam filter/bucket.

 

I can send mail from the host...

 

Any suggestions on where to start looking?  I am up for doing the work
in tracking this down but not sure where to start.
