finally I found the time to write down the configuration we use on our server to blacklist hosts that try to send emails to pre-defined nonexistent mail addresses. it uses only exim & postgresql & is (except for adding the "triggering" recipient email address patterns to the respective table) rather self-contained.

the documentation can be found in the article dynamic blacklisting with exim & postgresql. feel free to use/improve/comment/... the ideas!
