@f0x @emsenn It isn't supposed to mark it as spam if you have DKIM and SPF set up properly with your domain and server. I use protonmail, but there was news recently about them handing over login times and other information to authorities, even if they can't provide message data.
@theonefreeman except it's google. My mail setup has those things, but they refuse to accept it. I went with fastmail for now
