      What you did here was check for mails including that particular DNS name, an incoming message to your server may not have been sent from the 'MX' DNS name, so it would not have been found in your search.

      You may want to instead search simply for 191.it, or possibly 77.238 to see if this gets any additional hits.

      It may be worth having your user check with the sender to see if any failure receipts were received, and to forward those.  That would give additional info that should help in your log search.
