Should ODMR support be in the primary MTA queue? Or should mail for ODMR destinations be batched up onto disk out of the MTA's queue, and served by dedicated servers as in: http://www.plonk.de/sw/odmr/ It is far from clear that one wants to gum-up the active and deferred queues of a real MTA with ODMR mail. If we can deliver envelope + message to suitable stable storage, and use a standalone ODMR server to make said storage available to ODMR clients, that is likely a better solution and is much less intrusive. You just a need a delivery agent that records the envelope in detail and delivers to a maildir or similar associated with the owner of the domain. Then a non-Postfix server that supports retrieval. No pointless retries or gumming up the deferred/active queue unless the user connects, though your probably need a daily scan to bounce over-age messages. -- Viktor. P.S.
