Postfix 2.3-20051202 introduced conditionally compiled code for a "DELAY"
access(5) action, but this never became a default-enabled feature. You'd
need to compile Postfix with "-DDELAY_ACTION" to get it, and I don't know
how recently this was last tested. It may no longer work, and perhaps was
never ready for prime-time (otherwise might have made it as a standard
feature into some release).
