On one of my mailman lists a subscriber's messages keeps getting held for moderator approval with the implicit destination error.

This occurs because the list is not explicitly addressed in a To: or Cc: header of the post. E.g., the post is sent as a Bcc: to the list.The real question is why is this one person sending to the list this way?

I went in to the privacy recipient settings and set the ceiling to 0.

That's the one setting on the page that doesn't affect this. You can stop all implicit destination holds by setting require_explicit_destination to No.

Also, if posts sent to a different address are relayed to the list, you can add the different address to acceptable_aliases to avoid an implicit destination hold for posts relayed from that address.
