Sorry, the 'adhoc' logging subsystem is a preliminary implementation
that I wrote to get Postfix out the door. It is therefore not
adequately documented, not even the 'routine' logging.
Here's asuggestion: if all your probes are sent from the same IP
address 192.168.2.199, then please do:
# postconf debug-peer-list=192.168.2.199
# postfix reload
(debug_peer_list is used in some DEBUG_README example, and it is
documented in the postconf(5) manpage.
That will log the requests (nmot message content) and most importantly
the responses.

I see nothing in the MAIL FROM that would offend Postfix, so it
will be interesting to see what the problem is.
