Suspicious emails

What is with Norton designating good emails as suspicious all the time? need a one click solve for that.

At the moment you have to submit emails to Norton in order to be able to remove the designation “suspicious”.

I want to be able to just right-click and say: Not suspicious/I know the sender.

It happens so very often and I am sick and tired of it.

How can I turn that feature off?

If I cannot turn it off or designate it as not suspicious in a one-click action, then I think I will be moving away from Norton.

Any solutions out there?
