Ouch!  Sorry for the tech talk, often it's a useful habit, but not
always.

There are several addresses that Mailman uses that might plausibly be
called "the list address".  The one you are thinking of is often
called "List-Post" because there is a header, hidden by most mail
clients, by that name, to allow mail clients to automatically
recognize the posting address (some provide a separate command for
reply-to-list).  It is the address where members send posts.

But there's also the list owner's address (one might think of that as
"headquarters", and therefore "the list address").
