It's not something we are currently looking into. How is it better than DMARC?

I am investigating exactly the same thing. The problem is with virtualmin forwarding email:

Say I have virtualmin server with domain myserver.com set up with a mail alias *@myserver.com to forward all mail to example@gmail.com. Quite a common set up.

A user from 3rd party domain, say client@yahoo.com sends mail to me@myserver.com, the mail is forwarded by my server to example@gmail.com.

The issue is the From address is still client@yahoo.com but coming from my IP. and of course my IP is not in yahoo.com DMARC/SPF rules. This then looks like I am spoofing email addresses, bounces and/or gets me blacklisted.

I believe ARC is designed to mitigate this issue.

Ah, that is useful. I'll add this to my TODO list for future releases.
