As long as you never use it to *reject* mail, you should be fine.

SPF, by its very nature, can only give "yes" and "maybe" answers. It can
never give a definite "no". That's obvious, given the way it works.

So you can use it for whitelisting, perhaps, and exempt mail from
certain processing if it comes from a known-good domain *and* passes
SPF. But never for rejection.
