ACK - what I meant was each on their own 'condition = ' call.
(which a router may not be happy with anyway ...)

In the practical sense, any router that does not call a 'viable'
transport IS a 'null' router, though blackholing or specifically
transporting to /dev/null OR using an 'unseen' (that works) to reach a
router that is not 'null' may be considerably kinder to your queue AND
NOT generate DFB's
One might may or may not want suhc a router to verify. Or might want to
use the DB to verify instead of a router-walk at all.
BTW - speaking of DFB's - if you want your sender_verify probes to be
'handled' correctly, it may help to make their calls in such a manner as
to not appear to be originating on a zombified WinBox whose rDNS doesn't
match anything you have published in *your* DNS.
Check your logs for my attempt to honor your request to be 'CC'ed...
