"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Are you using postini, or is the recipient using postini?

I know postini requires (or has the option to require) all users to be added to the box, so make sure the user is allowed to send through Exchange to the Postini relay. That is an issue I see a lot with new / larger Postini deployments.
