Ten years ago there were people who believed that. I'm dismayed to see people still saying that today. SPF tells you where the sender asserts that its mail will come from. That's fine as far as it goes, but most senders do not actually understand mail very well, and their assertions are wrong. There is a school of thought along the lines of "tough noogies, if their SPF tells you to drop legit mail that's their problem", but that's a good way to make your mail users find a provider who's less wedged. An SPF pass is a reasonably strong signal that the mail did come from the purported source. An SPF fail doesn't tell you much.
