Thanks for the answer, Al. the message came from an external address that was e-mailing in to us, so I'm guessing it's something the contractor has done. Looking for big stick to beat him with now.

If the command is unrecognized, I have to ask where in the ORG this message was when the message popped up. Also, was anything installed by the contractor? If not, the contractor may have just changed the content types and it's mucking things up. Just a guess though.

Any ideas?

Could this be the cause? Win2k server running Exch2k. Thanks!
