Interestingly Messagelabs does just this:

X-Env-Sender: drew at
X-StarScan-Version:; banners=-,-,-
X-SpamReason: No, hits=0.0 required=7.0 tests=Mail larger than max spam

Please note this is made as an observation. I don't understand enough  
about all the different SA rules to appreciate what the best choice  
is (Yet!). Certainly I understand the issues of DoS and indeed the  
potential of missing large spam messages but I can also see the  
possible benefits of not scanning very large messages at all for some  
of my very old and underpowered machines, so I am following this  
debate with a keen interest.
