Hello,

I want to setup a mailing list with following properties:

All emails with explicit non-members with moderation option “Default Processing” are distrubuted to the mailing list. Emails from members are rejected. As example m@example.org is a member, and n@example.org is a non-member with Default processing moderation. An email

From: m@example.org Sender: n@example.org

shall be distributed, because n@example.org is а non-member, who can post. In my configuration however, the email is rejected, because m@example.org is a member and members may not post.

Is it possible to configure a MM3 mailing list, which accepts the above email, but would reject it, if the Sender: header is missing?

It's not really possible.

One thing is the messages senders method which returns addresses from places in

[mailman]
sender_headers:

which is from from_ reply-to senderbye default where from_ is the envelope sender. You could reorder this putting sender ahead of from, but that won't really do it because the rules chain processes member moderation before nonmember moderation so if any sender is a member, that will trump any nonmember sender.
