Could someone please remind me what the nuance is? > RitLabs publishes, as many others, a DMARC setting for their domain (v=DMARC1; p=reject; rua=mailto:[email protected]; ruf=mailto: [email protected]). This mailing list thus cannot generate a mail from you @ritlabs.com without this mail being rejected at all sites performing a DMARC check (it all started with Yahoo's p=reject a long time ago). We then updated Mailman and setit so that for domains with such settings, the From: domain ist rewritten to the mailing list. Best regards Johannes
