That's the good scenario. The bad scenario is called backscatter and is
when the notice is deliverable to the innocent third party whose address
was spoofed as the sender.

Set respond_to_post_requests to No on each list and set
DEFAULT_RESPOND_TO_POST_REQUESTS = No in mm_cfg.py so that new lists get
created with respond_to_post_requests = No.

Then Mailman won't send the “Your message awaits moderator approval”
notices.
