Meh.  There are certain deep and fundamental problems with this eminently natural feature request.

That is to say, you have to accept the RCPT commands BEFORE you get to see the email message.  And once you've seen the message, you have to accept it or reject it for ALL accepted recipients unilaterally.  That's just how SMTP works.

But what I do is...

I reject (action_bounce) all viral email.  Users don't have a choice to opt-out of virus protection.

I tag all spam (add a header, tweak the subject.)  Users are stuck with spam... I don't action_bounce it.  But they can set up custom spam handling preferences on their Inbox.

Users who don't get much spam just have it go into their Inbox, reducing the consequences of false positives.
