If you're running Exim version 3, add a configuration line of
"receiver_verify" somewhere near the top of your config and restart
Exim.
Then, spend some time upgrading to Exim version 4.66 since v3 is old,
deprecated and likely to cause you other problems.
That done (or if you already are running 4.x), put "require verify =
recipient" in the RCPT ACL and restart Exim.
The nonexistent recipients will then be rejected instead of
accepted-and-bounced.
