They are effectively scanning you for addresses anyhow - accepting the
messages is just giving you the chance to pay for bandwidth etc.
For exim 3.x use the various receiver_verify options - see
http://www.exim.org/exim-html-3.30/doc/html/spec_11.html#SEC326
Control of this is better in exim 4. Adding sender verification also
gets rid of stuff from unroutable senders - although spammers just use
someone elses domain - ie yours.
