The problem is well known but we have not found a good solution yet.

I see only two methods, which are not implemented yet:

1. Rather than rejecting connections when address harvesting is detected, act as if a  spamtrap has been hit.

2. Find a way to share black lists between servers (eg. starting some local RBL server to be used by backups?)

Anyone, more ideas on this?
