Klez does some very weird things with forged mail headers.  I received
mail on a VAX/VMS box that appeared to be a delivery failure notice. 
It's a cute bit of social engineering, presuming that you'll open the
message to see which of your messages bounced. 

Kinda loses momentum when you see the mail headers as plain text and
have to FTP the message to a Linux box to "un mime" it (DEC never built
autolaunching virus capabilities or mime decoding into their client for
some strange reason).  I got someone's infected copy of the Voodoo 3
driver installer as my free prize :-)
