Go one step further and prevent them from even entering the queue. Do
sender verification. In its simplest (and most widely accepted) form,
it just checks for a deliverable remote domain or deliverable local
user.
Sender verification is enabled by default in exim4 in the ACLs, so I
assume you're using exim3. In exim3, sender verification is controlled
with the main configuration option sender_verify:

Consider enabling recipient verification as well, with the
receiver_verify option:
http://www.exim.org/exim-html-3.30/doc/html/spec_toc.html#TOC326
And give some serious thought to upgrading to exim4. It's a truly
remarkable piece of software.
