Are you suggesting that we configure our e-mail servers to notify people upon automatic deletion of spam? Frequently, spam cannot be properly identified until closure of the SMTP conversation and that final 200 mMESSAGE ACCEPTED...or do you think that TCP/IP connection should be held open until the message can be scanned for spam and viruses just so we can give a 550 MESSAGE REJECTED error instead of silently dropping it? Because most spam originates from a bogus or stolen sender address, notification creates an even bigger problem.
