The -l option of dccproc does that.

They probably won't ever see the message.  However, rather than the
above, you might consider something more legalistic, since you mention
prosecution above.  For example, give a URL to a web page with your
unsolicited bulk email policy, which states that they owe you $500 per
message, or something.  Like shrinkwrap software licenses, you could
try to assert that by sending mail to your site, they have accepted
your policy.
