a different problem, and my question is whether this mechanism, MARID,
is the right tool for solving these three problems. I.e.:
1. 2821 HELO/EHLO domain and in-addr.arpa
Goal: Seeks to provide protection against hijacked machines sending
viruses/spam
2. 2821 MAIL FROM.
Goal: Seeks to protects domains from getting bounces from joe-jobs
3. 2822 From:/2822 Sender:
Goal: Seeks to protect domains from joe-jobs and phishing
