Postfix's built-in spam controls (such as RBL checks) operate like this. In the past, for 3rd party filters like SpamAssassin you had to accept the mail first; but if you use the above-mentioned "before queue" interface, you can presumably invoke stuff like SpamAssassin and ClamAV while the SMTP connection is still active.
