That's because exim's behavior (unless you have receiver_verify set to
true) is to accept the mail and then bounce it back to sender with an
undeliverable message.
One thing that's annoying, though, is if you have things set to do
domains with a default mailbox, you'll get all of the relay attempts in
that default mailbox. :) Better than the alternative, though.
