I changed the virus handling in filter() on in my mimedefang-filter. If
the virus name is 'sobig' to just dicard the message.

sub filter ($$$) {
...
       if ($category eq "virus") {
            md_graphdefang_log('virus',$VirusName, $RelayAddr);
                                                                                
            if ( $VirusName =~ /sobig/i ) {
                # if sobig, silently discard
                return action_discard();
            } else {
                # Bounce the mail!
                action_bounce("Virus $VirusName found in mail -
rejected");
            }
