hi,

More and more spam-filters seem to “know” if an address is valid or not, would love this future in SF too!(without having to keep up with every domain/AuthorizedTo-lists…)

I guess when a mail comes in the server first tries the destination server if it would accept it before processing it. Would help to keep the quarantine clean and maybe take some load. (and even better have some kind of a AuthorizedTo-cache list)
