The response from the remote server was: 550 5.1.1 : Recipient address rejected: User unknown in local recipient table

From the error message he listed, he is not trying to post contents of an email. Now that may be what he wants to do, but he is somehow trying to actually post his email. At least that is the best interpretation I can make of his post.
