[Mailman-Users] All addresses not on the local box bounce

[Cassandra Fleetwood]

Just installed Mailman 2.0.11
Configuration info:
Apache-1.3.23
Python-1.5.2
Sendmail-8.11.6
DELIVERY_MODULE = 'SMTPDirect'

I can create a list, subscribe to the list from an address on the local box,
and receive mail from the list to an address on the local box. All addresses
not on the local box bounce.
Any ideas?
