... the -00 spec does allow for the case where you decide -- before
fetching any part of the message -- that the originator is not worth
trusting, so you simply discard the URI silently.
How is that any different than sending a 5xx in response to RCPT TO:,
which is something we can (and should) do now?
Mainly in that you can do it minutes after receiving the TBR command
without needing to keep the TCP connection open.
