Which means that you can't run your choice of tests on a message during 
the smtp conversation before you accept it - at least without starting a 
new process for each one which is expensive for large programs like 
spamassassin.  And if you accept a message but don't deliver it, you are 
supposed to generate a bounce to the sender, but that is always the 
wrong thing to do if you think it might be spam or a virus.  Running 
your checks in time to do an smtp reject eliminates that problem.
