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.
