[Mailman-Users] problem with messages being held for moderator approval

[Josh Greenberg]

I am having a problem with messages being held that should be allowed 
through. The problem is always when people send to a list that has a 
list as a member. In other words, a user sends an e-mail to list A. List 
B is a member of list A so the message goes to list B as well. When the 
message gets to list B, it gets held for moderator approval even though 
the user and the list itself (listA at domain.com) are both on the Sender 
filters list. How can I get these messages to go through automatically? 
Thanks.
