I can't find a specific "official" method of doing this as there are no
logging abilities in that section of the email delivery.
There are a number of string expansions in the transport which you could
use to expand a string to cause a side effect.
Rig up some hideous thing either using ${run or ${readsocket to talk to
an external program that would dump the contents of the lookup you have
done on the command line/socket data.
Then make whole expansion ends up being the true or false that the
transport needs to operate normally.
