No, you still need an entire testonly-owner.config file.  Using a 
default config file that gets created by majordomo does not cause any 
message or header content to change on it's way to a recipient list.
The only settings you would change are the admin password, which every 
list owner should change as soon as their list is created, and the 
restrict_post setting discussed in our previous exchange of messages.
Remember, the point was to prevent spammers from using the address of 
the list owner, while still allowing list members to talk to the owner 
as necessary.  If the spammer joins your list, the whole game plan 
changes. ;)
