On an ESMTP capable sending host the message would be stopped before
being transfered.

However if this was done the message would *still* be transfered... the
only way to stop a message after the DATA part of the SMTP transaction
has started is to shut the connection down. If you do this the sending
host should quite correctly resend the message since the link failed
silently... so you will get lots of attempted resends.
