Dear Spammer Technical Support,
I realize you sent this via the Mega-D (aka Mega-Dik) Botnet so I can understand the $DIKSBJ choice of parameter name but it's just not that interesting. Perhaps if it's not a bug in your software, you might educate the user renting out your bots, on how to configure it properly. After all, they're probably already paying you large amounts of money for the service.
Here are recent examples of Subject lines when everything went smoothly:
Subject: Huge dimension gives increased force
Subject: Gigantic dimension is a great power
Subject: Prodigious preparation is to your service
Subject: Perfect proportions are easily attained
One more thing, the problem also exists with your blog spam...
