You can temporarily set the bounce configuration strictly on the large
lists.  On the "Bounce Processing" page, set

bounce_processing to Yes
bounce_score_threshold to 0.75

at this point you can

(1) Send a test message to the list and go through the member list and
    prune known bad addresses (they'll be "administratively
    disabled"), or

(2) set bounce_you_are_disabled_warnings to 0, then send the test
    message.  This will prune all the members whose addresses bounce
    "hard" immediately.

I suggest you look at the help for all the settings on the Bounce
Processing page in the administrative interface, and ask about
anything you don't understand.
