Just read it in place in the router.

What I recommend is putting in a reconf_outbound: router before the
normal router which sends to the customer-supplied server. In this new
router, have a condition based upon $message_age being greater than some
threshold. If this check fails, the new router will decline and
processing will fall through to the normal router. That way, normal
messages to well-configured hosts are optimised and using address_data,
but if the mail is old enough then you re-read the deliverydat data on
each delivery attempt.

# message must be at least an hour old.
condition = ${if >{$message_age}{3600}}
route_data = ${ complicated expansion }

You can also look at using a macro to abstract out the expansion, to
reduce the risk of errors creeping in if it's spelt out twice.
