[Mailman-Users] Installation/configuration problem

[Eron Armour]

Hi folks, I've set up a Fedora box, installed apache and mailman and set
up a list with not much problem. 
When I try to send to my list I get a bounce:

There was a SMTP communication problem with the recipient's email
server.  Please contact your system administrator.
            < localhost.localdomain #5.5.0 X-Unix; 69>

This is my first attempt at setting up a list so I'm not sure what to do
now. Any help would be greatly appreciated. -Thanks
