For me, having the "Dangerous" label is all that is required. By definition, all other incoming emails are safe.
I don't like getting every single email tagged with a useless label. It should at least be optional if users want the "safe" label.
Yes, I know that some users might not understand that Email Protection only scans emails arriving after protection has been turned on. This is why it is fine to leave the "safe" label turned on by default. Just please, pretty please, let users like me turn off the "safe" label!
Otherwise I'll just turn off the entire Email Protection, and that would be a shame.
