This rejects further recipients.
If you *really* want to drop the connection then use the drop verb, but
be aware that this will have side effects - if a delivering MTA has an
initial set of bad recipients for whatever reason and you are dropping
the connection it may then retry the whole transaction (including the
bad recipients) since from its point of view the whole last connection
went bad.
