Listserv supports something it calls 'list exits', which are programs called
in response to significant happenings (a bit of an old and crufty mechanism,
but better than nothing). Their manual documents the 'exit points' they
support. They all look quite obvious, but it might be of some use if
something similar is being planned for Mailman3. Section 5.2 of their
manual:
