It might work. Normally ratelimiting assumes that the sender IP is the
key but you could specify anything, including your to/from pair. So
sending email creates the pair and establishes a count. Then incoming
email is tested (but not incremented) against this pair and if it is > 0
then it's blessed. You could set the time limits to a few days and that
will allow data to automagically expire.
