There is no regex or similar, but you can filter the search used to
harvest the addresses -- see notmuch-address-internal-completion
(customisable under notmuch-send). 

You might find that putting a date limit would work; alternatively you
could tag messages from the dead addresses (eg tag:dead-address) and put
a "not tag:dead-address" in the filter field.
