Isn't this problem exactly the sort of thing that the DNS
was designed to solve?

Wouldn't it be nice if the NIC would establish a new top-level
domain, .list, populated with MX records pointing to mailing
list hosts? So that, for example, the list-managers posting
address would be email@example.com. Then it
wouldn't matter where the list happens to be maintained this
week. A list's address would never change, and it would be
easier for users to remember. When a list dissolves, mail would
bounce as "unknown host", meaning "list is gone", and no host
would be bothered with the next 5 years of bogus mail.

With lists the size of sun-managers, forwarding could be a very
big deal. If the MX records were in a domain independent of
the list's home, forwarding would never be needed.
