procmail does wonders, just don't call vacation for anything marked as spam. 
We use that plus some other checks:

:0 c
* !^Return-Path: <(www|nobody|apache|httpd|bounce|no-?reply|devnul|root|notify|owner-)
* !^X-Spam-Status: Yes
* !^List-
* !^X-Mailer: Accucast
* !^X-Campaignid:
|/usr/local/bin/vacation $VACATIONOPT

As for not accepting then bouncing -- do virus checking in a milter (we use 
ClamAV), and push a list of valid users to your secondaries. This sort of 
this in access.db:

To:westnet.com  ERROR:5.1.1:"550 User unknown"
To:chris@westnet.com	OK
To:root@westnet.com	OK
To:postmaster@westnet.com	OK
To:... etc
