Is it right to blame Google/Yahoo for deprecating an email forwarding service?
Documentation for ARC is pretty sparse.
The instructions for setting it up in Exim (default MTA on Debian systems) can be found here: https://github.com/Exim/exim/blob/master/doc/doc-txt/experim...
(AFAICT, there is absolutely no mention of ARC in the main Exim documentation: https://exim.org/docs.html)
