doable - but the challenge there is that if we want to generate a proper
bounce we will have to accept the mail and send back a bounce - that
however makes us vulnerable to bounce blow-back (if say somebody fakes a
an email sender and we direct the bounce in that direction back).
The other option is to reject the RCPT TO at SMTP time with a message
like the above on our frontends - the problem there is that is it up the
sending MTA to wrap that text into a bounce that might or might not be
parsable by a human :/
