DMARC helps servers verify that mail is legit. Messages are signed by a private key, and the receiver checks it against a public key over dns. The "from" field has to match the actual sender's domain. When sudoroom.org sends you mail, it has to say "From: ... sudoroom.org" or it will fail the test. We can't send mail that says "From: Andrew R Gross <arg5029(a)gmail.com>" because we don't have the private key for gmail.com.
