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.
