It is not doing that; it's sending a bounce for that address, to the
envelope-sender of the mail.
But this is not (now, in the age of spammers) the correct thing
for you to be configured to do. You should reject nondeliverable
recipients at SMTP time rather than doing accept-then-bounce.
For Exim this means checking recipient account names in your
recipient ACL.
