      (if i understood correctly the needs of Giorgio)
      Can be the following points the way to obtain round-robin delivery based on
      sender address/ip?

      1. change the "incoming queue" directory structure indexing sub-directories with
      a per-sender index
      2. changing the algorithm used by qmgr to move email from "Incoming" to "Active"
      queue, (a foreach over subdirs)

      This increases disks i/o but you can obtain a pretty fair delivery between senders
