Comment on How do email scammers spoof my email?

When you send an email to a mail server, you can set the “FROM” address to literally anything. The mail server does not care and forwards stuff on. Anyone can run their own mail server anywhere that will dutifully just relay emails, which is what spammers often do. There are entries in DNS called SPF records (Sender Policy Framework) which mailservers use to validate that the FROM address coming from the mail server matches with a list of allowed mail servers IP address(es). If it doesn’t match it gets sent to spam.
