That's what I've been trying to do for the last few days. In my experience, a Whitelist allows everything, just like a Blacklist denies. I'll keep an eye on this post.

I don't use the Friends feature because, according to the doc, ONLY friends can send mail. I, of course, get mail from clients etc who I don't know.

If there's a way to have a universal Whitelist or user Whitelist, I sure haven't found it.
