Lists never send messages. You'll never receive genuine mail with an
SMTP reverse-path of <exim-users@???>, and as such, the list can be
set up to refuse to accept bounces.

If you were to autoreply to a list message, that goes back to
exim-users-admin@???, which is the list software -- not to the
list. The list software will probably just keep count of how many times
you do this and unsubscribe you if you do it too much. A much less
problematic failure mode than some of the other possibilities.
