It appears that Steffen Nurpmeso <[email protected]> said: >(The thread continued on ietf-smtp@ due to request.)

This is not a new suggestion, and nobody I know has ever implemented it other than as small scale experiments. The point of greylisting is to test the retry logic that every real MTA already has, not to invent yet another hack on the client side. MTAs run their own retry schedules and it would generally not be easy to have special schedules for specific messages. R's, John
