I am receiving a bunch of these messages and they appear to be coming from Mac computers.
Do you have Mac clients on your network?
If so, they probably have email setup incorrectly.

Yes, we have Mac's clients on our network. Any idea what I should tell my Mac guy to fix to correct this? I don't know the Mac side.
Just off the top of my head, it looks like the Mac mail client is trying to use authenticated or encrypted connections first and then failing back until something actually works. Have him verify the server authentication and encryption settings are correct on the clients.
Tell him to check the login info for the email account(s) that they're connecting to on your Exchange server, to make sure they're correct.
