Honestly, I'd want this as a default. I wonder if a mailserver can be configure like this. Doesn't sound too hard, does it?

Believe it or don't, most mailservers actually are set up this way, but it's completely invisible to the user: https://en.wikipedia.org/wiki/Greylisting_(email)
Greylisting is not perfect, not even close, but it allows servers to reject huge amounts of garbage mail while allowing new mail from unexpected parties without user intervention.
