Hellow Julian, I believe "Reputation" is something that's difficult to define in the world of email. I'll leave links to some helpful documents: [1] Peter's thoughts on Email world's Chaos: <https://nxdomain.no/~peter/they_do_not_understand_mail_at_all.html> [2] Laura's short comments on Reputation: <https://www.mail-archive.com/[email protected]/msg26171.html> [3] Brandon's long comments on DKIM and Google: <https://gitlab.com/soyeomul/Gnus/-/raw/karma/DKIM/GMAIL-POLICY?ref_type=heads> Sincerely, Byunghee -- ^고맙습니다 _布德天下_ 감사합니다_^))//
