[Mailman-Users] 'General posting filters' explanation required

[Mark Martinec]

Under 'Privacy Options' in the section 'General posting filters'
there are three settings:

  1. Must posts be approved by an administrator?

  2. Restrict posting privilege to list members? (member_posting_only)

  3. 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
