[Mailman-Users] Not delivering to local users

[rich at edj.net]

I have Fedora 10 running postfix-2.5.6-1.fc10.i386 and  
mailman-2.1.11-5.fc10.i386.
I can send and recieve email fine. Mailman recieves all emails fine  
but only sends to remote users but not all remote users. Recipients on  
the local machine do not recieve any emails from mailman. I would like  
to figure out how to fix this. My settings are basically unchanged  
from an older Fedora 6 system. smtp-failure is full of entries like  
this:

Jun 01 12:30:34 2009 (1059) delivery to user1 at gxxx.xx failed with code  
-1: please run connect() first
Jun 01 12:30:34 2009 (1059) delivery to user2 at xxxxxxx.com failed with  
code -1: (111, 'Connection refused')

My mm_cfg.py:

DEFAULT_URL_HOST   = 'domain.net'
DEFAULT_EMAIL_HOST = 'domain.net'
MTA = 'Postfix'
POSTFIX_STYLE_VIRTUAL_DOMAINS = ['']
VIRTUAL_HOSTS.clear()
add_virtualhost(DEFAULT_URL_HOST, DEFAULT_EMAIL_HOST)
