[Mailman-Users] Setting up an open-posting list

[H. Wade Minter]

I'm trying to configure a Mailman 2.1.6 installation to have an 
open-posting list.  That is, mail from nonmembers should be immediately 
accepted and forwarded to the list.

In Privacy Options -> Sender Filters, I have generic_nonmember_action set 
to Accept.  I also have accept_these_nonmembers set to a regexp of "^.*", 
and all other _these_nonmembers options are blank.

However, nonmember mail keeps getting sent to the list moderator for 
approval.  Am I missing a setting to allow open posting?

Thanks,
Wade
