[ale] Odd question. How can I filter my SPAM box?

[byron at cc.gatech.edu (Byron A Jeff)]

I've been collecting spam to build a huge corpus for training my spam filter
tweaks (whenever I actually get around to it). I learned today that I've
actually been saving viruses with the .cpl extension.

I'd like to get rid of them. I have procmail. 

Is there any way I can filter out those messages from this SPAM box?
