How to solve spam and unwanted calls. Simple way, and I've been saying this for decades.
WHITELIST. If you're not in my phone directory, you won't get
through. If you're not on my email address book, you won't get
through. Better email authentication would be nice too.
Server A is spoofed to send mail: user@servera.com
Server B receives the message: To UserA@ServerB.com
Server B queries Server A to see if that message ID was sent.
Since it's spoofed, the message is not verified and dumped into the
black hole of unwanted bits. Do this and the entire spam problem
goes away. Why? Because of the whitelist and verification.
Will it be more inconvenient? Sure it will. You'll have to ask your
family and friends to add you to their email address book and phone
directories, but at least you won't be bothered at dinner time by
some idiot wanting to put aluminum siding on your house when
you live in a 25 story apartment building...... (happened to me.
Was nice to see the trucks pull up, look, and pull away.) |
