Message size

Yesterday, a client tried sending a 7MB file, O365 told the client that PMG rejected the message as being too large:
Remote Server returned '554 5.3.4 < #5.3.4 smtp;550 5.3.4 SMTPSEND.OverAdvertisedSize; message size exceeds fixed maximum size>'

When I checked the logs using: /#pmgMailTracker, I found everything was delivered - Status column reports "accepted/delivered"

I ran: grep -ris "Message size exceeds fixed limit" /var/log/mail.log

The 7MB message was not included in the list of messages, curiously, the messages I found searching mail.log, were not found via Tracking Center

Any idea what is going on?
Please post the mail.log (redacted if necessary) for the timeframe of this mail.
