Sample spam template
         

<p>Most high-volume spam is sent using a tool that randomizes parts of the message - subject, body, sender address etc. From time to time, you'll see a run of messages in which the spammer has made a configuration error, so the subject appears as $RAND_SUBJ instead of whatever the spammer intended. You can also often guess the general form of the template that the spammer is using by inspecting a number of messages.</p>
