So you know the address which is being sent messages from a list, but
the address is not a member of the list you are looking at. Is the
address a member of a sibling list? I.e. does the list have any
Non-digest options -> regular_include_lists and if so, is this address a
member of one of them?

If not, there is another list in another Mailman instance which is
sending these messages. Examine the Received: headers of the received
message to determine the IP address of the server that's sending them
