In a word, Yes
It's nothing more than a TXT record that spells out authorized servers for the domain
There's 2 options (really 4 but nobody uses the other 2) tag or deny depending on if you use ~all (soft fail/tag) or -all (hard fail/deny) at the end. 
You can check the record at MXToolbox.com
I usually recommend start with soft and switch to hard after you've worked out any kinks.

Is this a problem that SPF is designed to solve?

Oh man.  Am I the only person who emails myself things from time to time?

Also, a lot of my IoT devices that send email are configured to send from/to the same address.   So for my purposes that rule would not be good.

That said, I do have a customer complaining today that he is getting a lot of messages about “I recorded you!" being sent from his own email address.    I wonder if the efforts are better spent on analyzing other aspects of the messages for detection.
