there's ${message_age} for you. its perhaps not impossible to cook up
a condition that, based on the ${sender_address} looks up a value for
${message_age} from a convenient source, and :defer:s the message, if
its found to be too young.

this immediately voids your problems of associating a message with its
owner and the moving of messages between queues. as for
administration, i guess you're left parsing outputs for exim -bp*,
-Mv(h|b) and friends... this sounds to be ways harder than the actual
configuration :)
