If the msg doesn't show up in your MTA's log, then MAilScanner can't 
"loose" it.

The obvious is to ask the sender to provide an smtp log snippet which
shows that they did indeed send a msg and you accepted or rejected.
Although the sender never likes that approach "Show me what you sent,
before I loose sleep over it" will save you a lot of time and headaches.
