I don't see that. I see the rcpt command, then the data command. The 450
code it shows should really be a 5xx code because it would indicate a
permanant error. If the user is unknown now, why should they be known in
say 4 hours? The 554 response is just an extension of the 450. 450 was
saying user not known, th 5xx code was saying no valid recipients.
