Continuing the discussion from Google "no-reply" user pending approval:
I am using Gmail for my incoming emails (following this guide). When I recently signed into that Gmail account from a new device, Google sent me one of those security warning emails: “got a new device? Review sign-in from Samsung Galaxy S7”. Discourse correctly rejected this email with an
Email::Receiver::AutoGeneratedEmailError but it nevertheless created a staged user for email@example.com. Can/should this not be avoided, given that discourse correctly noticed that
the ‘precedence’ header is set to: list, junk, bulk or auto_reply, or when any other header contains: auto-submitted, auto-replied or auto-generated.
