I think they must have been posting via hyperkitty. The first received: line is localhost then the mailman server. Is there a way to turn that ability off?
If the posting is from Hyperkitty, there should be a
User-Agent: HyperKitty on <list URL>
header.
Are the spammer's list members? If so, you need to remove them and then
set Default action to take when a member posts to the list to Hold for moderation. That way, when a new member posts for the first time,
the message will be held and if it's spam, you can discard it and set
the member's moderation action to discard. and if it's not spam you can
accept the message and set the member's moderation action to default
processing.
Also setting Member Policy->Subscription Policy to Moderate or Confirm, then Moderate will prevent a non-member from posting.
