@f0x Oh I see.

As you said, it's when they please; the only way to ensure something works with Google's moderation policies is to use Google.

Fastmail isn't self-hosted, and I've never had any problem with my emails going to Google accounts, but that might change. Or maybe I have had problems and just not been aware.

@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.
