I believe that all messages need to have a valid return address, period. If the sender doesn't want to accept a reply, then they shouldn't send the message in the first place. Provisions need to cover the current practice of spammers of taking the opt-out info and sending it on to more spammers. You decline 1 list and end up receiving many more unsolicited messages. Messages that attempt to change your computer or its settings should be considered by the act. Malicious acts should not have to be tolerated by anyone.
