Look at the IndieGoGo header image he's using. It's a screencap of Gmail's spam folder with 5,048 messages. Hasn't this clearly been solved?

I get MAYBE 2 spam emails a month that gets through the filter, and my address is pretty easy to harvest.

So is this still a problem?

It's a problem in so far as I'll occasionally miss real emails because they get binned as spam.

Yeah, I've only had this happen a couple times, and it does make you trust your spam system less.

That being said, it's seems to be getting better as more companies embrace SPF.
