[Mailman-Users] Shunting problem

[cary]

- I create a new list
- Subscribe my self to the list
- Send a test message
- Mass subscribe 50 email addresses to the new list
- Send a message

It never arrives and it shunted. I checked the error log and I get this.
This is a little frustrating as new lists work but fail the moment I add
new users. 

Any pointers? 

Thanks, 

Cary.
