Create a User-controlled Safe Sender List
I have used the domain blocking feature in Yahoo Mail+ to try and control the large number of daily spam emails I receive and it is an ongoing battle. While that domain blocking works, it is time consuming and the spammers keep coming up with new bogus domains. It would be much more effective if Yahoo would create a “Safe Sender” feature that would allow listing only sender email addresses I would like to receive email messages from. My Comcast/Xfinity account has this feature and I use it to effectively and completely eliminate receipt of all unwanted emails. Basically, I add the addresses of desired senders to the list I want to hear from, and emails from anyone not on the list are not delivered to me. Make the Safe Sender list available as an option for users who clearly understand the risks associated with its use, and structure it so it is controlled by the user and can be toggled ON and OFF. Yes, there is always the possibility of missing an email from a sender not on the list; nevertheless careful management of the list avoids this problem. Please consider this recommendation.
