I happen to be starting testing in a related area, will probably have more info
in a few days.
*Meanwhile* .. how about 'AND' ing in the Message_ID (in the acl) PLUS the
$tod_<something> (at router/transport time) so as to arrive at a custom-flag
with unique-identifier.
Not sure if that is 'early' enough, but perhaps it could be made to work for
whatever you are attempting if you used a two-stage router/transport coupled
with 'unseen', wherein the first stage set the $tod_<something>, and the second
effected the 'special' delivery.
One might then also strip these flag headers and replace them with something
more human-readable as a final step. Such as whatever the original intent was -
but no longer 'multiples' of same.
HTH,
