setting up spf on my domain

I need a step by step guide to setting up spf on my domain, i currently use exchange server but as i send out and receive using a spam server the spam server is the first place the mail hits and is also used as a smart host on the send connector, i'm not sure what impact that has on the spf settings?

I wear a lot of hats...

"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.
