Recently I’ve received a number of spams where it looks like the spammer hasn’t set up their spamming tool properly, containing just placeholders:

06/03/2007 (13:53 GMT +03:00)
1.0
Content-Type: text/html
Date: %CURRENT_DATE_TIME

%MESSAGE_BODY

C’mon, if you’re going to spam a message to thousands of people, at least test it first!
