"To control spam, I now allow incoming messages only from senders I have approved beforehand.

"If you would like to be added to my list of approved senders, please fill out the short request form (see link below). Once I approve you, I will receive your original message in my inbox. You do not need to resend your message. I apologize for this one-time inconvenience."

I see this probably once a week, usually from someone asking for advice or seeking help. Invariably, it's someone I don't know.

It's a lousy, absolutely rotten way to control spam. It's inconvenient and it adds an extra step to communications. It's also inevitably something that I throw right in the trash.
