Google Apps (or whatever it's called now after the last dozen name and service changes since "Postini") does offer a whitelist function, but as far as I can tell it's there only to placate users. Whitelisting domains or individual email addresses globally, or per user seems to have no bearing at all on whether they will show up in your inbox... Postini used to work flawlessly, it's hard to imagine how they could have screwed it up so badly.

It’s AI above all else. It seems instead of a rule that says all emails from these people are ok, they’re too reliant on ai filtering based on the content. They’re probably trying to prevent spoofing.

I use gmail and they know who is sending. I got an email today with a gmail flag saying “this user sent from a different email address previously”

In gmail, you can create a filter to skip the spam folder. I regularly receive emails where, at the top it says "this would have gone to spam, but you told us not to send it there".

I doubt this affects things when messages are rejected at the protocol level, but if your problem is emails showing up in the spam folder, this might fix it.
