Bullshit. You can set it up and gmail will reject your mail but if you relay it through eg icloud it will get delivered *even if that fails SPF.*
Google hates email because they don't control it. So they don't deliver for small mail operators no matter what and push their "rich" emails that only work on gmail.
Fuck Google. Don't use their software, they'll just trap you into some shitty Facebook-like silo.
