Worst infected email?

I thought you might find interesting that an email was sent to us with 3 different viri.

The email itself had Kak, the Word attachment had Smac and a parallel message had the MTX/Matrix virus (how that one works).

Is this a record? Has anyone had worse or similar?

BTW the sender (part of a 40,000 employee worldwide company!) has sent Kak and MTX repeatedly. We have informed them, and even recommended a Free virus scanner (AVG from www.grisoft.com) which would catch all 3.
