Sounds like this change in exim 4.91+fixes:

JH/05 Bug 2273: Cutthrough delivery left a window where the received messsage
      files in the spool were present and unlocked.  A queue-runner could spot
      them, resulting in a duplicate delivery.  Fix that by doing the unlock
      after the unlink.  Investigation by Tim Stewart.
