That would only be useful if MailScanner went through each message 
individually, scanning them one by one. But that's not how MailScanner 
works. For efficiency, it works on batches of messages. So the virus 
scanner, for example, is called once for the entire batch of messages, 
not once for each message. All the messages in a batch are processed 
together at each stage of the process. It scans them all for RBL hits, 
then all of them with SpamAssassin, then all of them for viruses, then 
all of them for HTML nasties, and so on. So it wouldn't actually give 
you any useful information whatsoever.

Which is why I haven't already done it myself.
