Check the SMTP Logs and see if it tells you which command is the culprit.

This all seems to be going fine, but an error is coming up in the Application log of the ISA server every couple of minutes: "An unknown SMTP command was used." Source: Smtp Evt, Event ID: 20031. Mail seems to be flowing normally. Is this a problem? It'd be nice to get the errors to go away. Related info: The message screener is installed on a separate computer (not on the ISA server or the Exchange server), but I haven't been directing SMTP traffic through it yet. Later today or tomorrow.
