How to implement a Postfix spam trap?
Spam trap
Dear lazyweb, I am considering to implement spam traps and evaluate their efficiency. The idea as rather simple:
- publish some real-looking email addresses on websites, in ways that no human would use them to send legitimate mail, for instance in hidden texts, or in texts clearly stating they should not be used;
- when my mail server receives a message for one of these address, blacklist the originating server for some time so it cannot spam real recipients.
