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.

I hadn't previously seen an entire spam template before, though, so I thought it was interesting enough to share this one, which a spammer inadvertently sent out. It's nothing you couldn't have guessed, but here it is. Note that even the hashbuster text is generated from a fairly small set of options.

Update: 02 February 2009 - a reader comments:

That's a DarkMailer template. It's also promoting "Discount Pharmacy", which is hosted using hijacked Windows 2000 or Windows 2003 servers. (In this case it's Windows2003 Standard Edition, a server named "COFFEEBEAN")

In fact, the advertised domain is hosted on not one but six servers, scattered all over the world — Russia, Mexico, Korea, Puerto Rico and the United States, all apparently belonging to different organizations. Some — probably all — of these servers also do double duty as name servers.
