Why would anyone even allow the biggest man-in-the-middle on the Internet to route their e-mail in the first place? It's a situation that will never be private and secure.
A smaller man-in-the-middle would be more secure?
I mean if email forward is really necessary (in my case yes) and successful delivery of email is really important (so I don't want to use my own VPS and the headache it brings) are there any better options for me than CloudFlare? My domains already use CloudFlare for their CDN etc.
If it's smaller and not connected to the US intelligence agencies, it certainly would. But if you use CloudFlare to begin with then there is no absolute notion of security and privacy, but this is of course a viable option if one doesn't do critical, important stuff.
