SPF does not in itself break email forwarding. SPF tells MTAs where mail with
certain senders may originate from. It's their job to know if the recipient
forwards mail from the connecting host. It can be tricky, but it's not
impossible in principle. Applying SPF without thinking is incompetent and
will cause false positives.
