The rub is, I want all emails to presid...@example.org to be forwarded to presidents_real_addr...@gmail.com. Since the forward happens at mail.example.org, the "from" is from some other domain from example.org, so it fails all the tests.
Indeed: your solution is known as "SRS" (Sender Rewriting Scheme) and it has multiple implementations. If you forward mail, you will break SPF unless you fix the envelope sender so that it uses a domain that permits the example.org server to send for it.
OR, you could instead deliver to a POP mailbox locally and have users fetch from there instead of simply forwarding mail to them. This also avoids a completely distinct problem of places like GMail deciding that your org's mail server is a spamming service because it is forwarding spam. If users POP their mail instead of having it forwarded via SMTP, that does not happen.
