Greyfix
I've written a small greylisting daemon for Postfix. It is written in Perl and uses PostgreSQL as database.
The main advantages are:
- it works ;)
- it is privacy friendly, i.e., it stores only one hash of the usual triplet (sender, recipient, class C net) and the last use time
- 3-clause BSD licence
