How do I beat this spam?

[Peter Ong]

Hey Alex,

Sorry about that. I didn't know about pastebin.

Here's the original message with headers:
http://pastebin.com/NpZnVU2T

Here's the original as rendered by my mua:
http://pastebin.com/xRNU7h34

So, how do I beat this spam when it comes in as the original email? Does MailScanner scan the message too in the form my mua reads it?
