It's the SMTP filter's response to an SMTP command it doesn't recognize; much 
like Scotty's ramblings about not being able to "get any more from 'er, Cap'n".
Check your event logs for the specific command that it choked on.

  Has anyone run across this yet? In the event viewer, I am seeing this daily:

  Event ID 17220
  "An unknown SMTP command"
  Source: smtpevt

  I am running ISA on a member server, and behind it on another server is 
Exchange 2000.
  I can't seem to find out any information on this error?
