    2020More generally, you're focusing on a specific piece of technology, SPF (or DKIM, or SMTP callbacks, or whatever else this might break), but that's too narrow a focus. What people seem to be missing is that regardless of SPF, or DKIM, or anything else, it's just generally a bad idea to send mail claiming to be from (say) gmail.com if your mail server isn't gmail.com. There are all sorts of possible reasons that some recipients will think you're forging headers if you do that (including naive custom filters on the receiving end), and the mail won't be delivered. The average user isn't going to expect that problem.
