Not trying to pee on your bonfire :), but have you thought of just
blocklisting a sender|client who has hit a certain reject amount within a
specified period, and putting a contact address in the rbl reply? Then
whitelist the rbl contact address for everyone except certain permanently
blocked, (and staying that way), clients|senders|helo's. That way, they
get an address, (and message to that effect), that they *CAN* contact if
the block is a mistake.

It would appear you are trying to make too much work for yourself with
this one:)
