MimeDefang (http://www.mimedefang.org/) allows a simple but comprehensive approach. It runs as a sendmail milter which allows rejection based on the scan results before accepting at the smtp level and acts as a wrapper for your choices of scanners and other tests. Spamassassin and clamav are good starting points - I'd suggest that the OP use it to add clamav to the Kaspersky scan. I don't think anything but a sendmail milter can run the scans at the right time during the smtp conversation to reject based on content without having to construct a bounce message. (Viruses should be silently dropped since there is a near 100% chance that the sender is forged, but the sender deserves a polite rejection notice about other content filtering choices). -- Les Mikesell lesmikesell@xxxxxxxxx
