And I forgot to mention: doing the spam scan in the ACL makes it happen
at SMTP time. This way you have the chance, to reject the message at
SMTP time already, leaving the responsibility for the message at the
senders side.

If you scan it at transport time, there is no chance to reject it,
everything you can do, is tagging it.

It depends on your sites policy, if you're allowed to reject messages,
just because your SpamAssassin rated them with a high spam level.
