Exim 4 already has more explicit SMTP error messages. Here's an example
of what you might see in response to a RCPT command that triggers a
sender verification:
550-Called: 127.0.0.1
550-Sent: MAIL FROM:<>
550-Response: 554 buildaddr: no host
550 Sender verify failed
Arranging to send a separate message to the postmaster as well is much
more complicated. And you wouldn't want to do it for every message,
would you?
