I have reverse DNS and SPF, but not DKIM and I don't have that many issues getting my email delivered. I did have issues with AOL, but once I registered as the contact for my IP address with them, those issues went away. I've also had one or two issues with GMail over the years, but last I knew, it was okay (I normally don't deal with GMail addresses that much).

Then again, I've had my domain for 17 years, self hosting everything for 16 years (with the occasional IP change, but I think I've had the same IP now for almost ten years so go figure).
