The problem is that spam is often unbouncable (or if bounced will go to the wrong place). Discarding messages without bouncing is bad for false-positives. So the ideal solution is to send a 5xx SMTP message and drop the connection when you see a spam and never queue it. -- http://www.coker.com.au/selinux/ My NSA Security Enhanced Linux packages http://www.coker.com.au/bonnie++/ Bonnie++ hard drive benchmark http://www.coker.com.au/postal/ Postal SMTP/POP benchmark http://www.coker.com.au/~russell/ My home page
