Comment 3 for bug 266324

Is there anything in accept_these_nonmembers?

What is generic_nonmember_action?

If one or the other of these settings don't explain the
issue, then I'm afraid that without specific information as
to the headers of the post as received by Mailman and
specific list configuration information, we aren't going to
be able to understand what happened or if there is a bug
involved.

In any case, I am moving this from 'patches' to 'bugs' for
the interim as it clearly isn't a patch.
