How about "Doesn't work and makes the problem worse"? Is that a good enough reason?
No, because I've used it, and it worked fine. I know a couple people that use it, and it works for them too. I've heard of others that use it or similar systems and they have been happy with them. In fact, I have yet to hear of anyone actually having a problem with such a system. There are some systems that will not send a response back to the sender for confirmation and others that simply ignore an e-mails from address not in the whitelist.
The primary issue is that there is no such thing as positive sender identification with respect to email. I can't verify that a stranger is who he says he is. I can't even verify that my whitelist is who they say they are as they can be compromised fairly readily and then their machines start spewing spam.
Easy enough to figure out. Look at the content, realize it's spam, and inform your friend/colleague/contact of their problem. Been there, done that. Very simple. 99.9% of the time the person does not have it happen to them again. (The exceptions have been some mailing lists that occasionally have a spam message get through whatever filters they have in place.)
