The usual implementation of DNSBL systems is to check the client IP address as soon as the TCP connection comes in, and disconnect with an appropriate error message if it's an IP address that you don't like. That saves a lot of bandwidth, and the mail is not discarded, it is left on the sending machine to be bounced in an appropriate manner back to the sender. -- 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
