I started off using postgrey but switched to sqlgrey as it is (or at least was then) pretty clever in learning about systems that retry correctly. http://sqlgrey.sourceforge.net/ # The main drawback of grey-listing as it was done in early implementations # was the delaying of legit emails. # # This is nearly solved by the auto-white-listing mechanisms built # into SQLgrey: # # When a sender has been seen coming from a given IP address, it # is automatically accepted when coming again from the same IP address. # # When several senders from the same domain have been seen coming # from the same IP address, senders from the same domain are accepted # when coming from the same IP address. # # The delay shouldn't really be a drawback anymore: users will only # experience delays (mostly in the 6 to 30 minutes range) when receiving # the first email from a given sender.
