send all senders to junk if not in address book
I need to send ALL emails to Junk unless the sender is in my address book. This seems so obviously needed that I was sure it's there, but I can't see a way of doing it.

What you want is possible by using Filters generall described at https://support.mozilla.org/en-US/kb/blocking-sender but specifically you must use "isn't in my address book" and then pick the address book

Thank you that solved the problem. I somehow didn't see that setting at the bottom of the drop down list. I only wish this feature was avaiable on a client on the apple phone. If anyone knows of an app that offers this feature for the apple device, please let me know.
