This is not quite true. I can envision a system that automatically quarantines (rather than discarding) suspected spam. It would then send e-mail back to the sender telling them how to take their message out of the quarantine area and have it delivered to the list (presumably by entering a one-time password on a web site). A message that was stuck in quarantine for more than a few days would automatically be removed. As spammers typically do not bother to use valid return addresses, this technique should be sufficient to tell whether a real person has sent the e-mail, or whether it was created by a a bulk mailer. While still not perfect, I'd image this approach to eliminate most spam without inconveniencing subscribers too much.a "moderated" spam filter would be nicest, but this means that someone has permanent duty for letting falsely blocked mail pass,
