I saw there's a SPF setting to prevent spam spoofing.
Which of the following should I use?
fail: the mail is a forgery, and you can reject it with confidence.
softfail: the message could be a forgery.
pass: the mail is not forged, but that doesn't mean it's legitimate.
neutral: The domain owner has explicitly stated that doesn't know whether the IP is authorized or not.
