With SPF, DKIM, DMARC, coupled with blacklists and the reputation system of big mail providers that's making it difficult to host your own email, it's actually quite to impersonate an email address.

Try it, then see how many times you can hit a @gmail address.

I found that this does not stop one from sending emails that appear to originate from addresses like [email protected] as long as the contents of the email are different from known spam emails. They are not flagged by GMail at all as long as you send them from a reputable email server through services like mailgun.com.

SPF will catch these really easily.
