I would probably have gone with:  Palm the workload off onto an external
list server, that already automatically handles subscriptions and
bounces.

In the changeover period, it probably is best to individually contact
each subscriber with a resubscribe message to clean up your list.  There
probably are some people who've just hit the "this message is junk
mail," on their original subscription, instead of bothering to
unsubscribe.  A bit of a braindead thing to do, and problematic if it
reports the message externally.

Sendmail is supposed to have validity testing, though I don't know if it
can handle your problem (smartly dealing with individual duff addresses
in a big list of addresses).

Don't send private replies to my address, the mailbox is ignored.  I
read messages from the public lists.
