'General posting filters' explanation required

Under 'Privacy Options' in the section 'General posting filters' there are three settings:
Must posts be approved by an administrator?
Restrict posting privilege to list members? (member_posting_only)
Addresses of members accepted for posting to this list without implicit approval requirement.
I must confess I find the interaction between the three settings unintuitive. I have to read '(details)' every time I set up a new list and when explaining it to a new list moderator.
After all my re-readings I understand the interaction between 2 and 3, but please somebody explain the interaction between 1 and the other two. (and add '(details)' entry to the first item as well).
Regards Mark

Number one is just about moderation. Numbers 2 and 3 are about whose posts are allowed through. If you are running a moderated list then (I believe) the people from #3 are also allowed straight through. There is a chart for the 2-3 interaction in the admin docs that I have prepared at www.aurora.edu/~ckolar/mailman. There is really no interaction between 1 and 2 as all postings are held for approval (even if they come from an off list poster).
Cheers.
