[Mailman-Users] Posfix/Mailman "relay access denied"

[Tony Bibbs]

When sending mail to a test list I setup I get "relay access denied".  
The maillog looks like this:

www root # tail /var/log/maillog

I assume this is somehow suggesting I don't have the virtual domain 
setup right but I'm not sure what I need to tweak.
