I'd like to restrict message acceptance on a per-list basis to the owner or moderator, so that simple subscribers cannot send messages to the list. But I don't want the owner/moderator having to moderate own messages, so the member setting "hold for moderation" in Postorius isn't applicable.

I have just tested a variant of this as I got curious: You find the member you want to be able to send emails without moderation, then set Administrative Options to "Accept Immediately (bypass other rules)". That works. I have found no other ways, though.

Or you may wish to set the owners/moderators subscriptions to "Default processing" which will still apply subsequent rule checks.

I.e., set Default action to take when a member posts to the list to Reject (with notification) and set an appropriate notice (currently can't be set in Postorius - set it via 'mailman shell') and set Default action to take when a non-member posts to thelist to Discard or perhaps Reject but this creates backscatter.

Then ordinary members have Moderation set to List default and owners/moderators have it set to Accept or Default.

The problems with this are sall the owners/moderators need to be subscribers and there are maintenance issues with adding/removing owners/moderators.

A better way to do this by sharing a "moderator password" for the list among the authorized posters. See <http://mailman.readthedocs.io/en/latest/src/mailman/rules/docs/approved.html> for how this is done to pre-approve posts. Then set the list to Discard/Reject all posts, and people who know the "moderator password" can still post. There is still an issue in that the password needs to be changed and redistributed when people become unauthorized, but this is more secure as regular moderation can be fooled by spoofing the sender.
