higgsbosonGoogle now blocks spoofed emails for better phishing protection
I.e. it’s now even harder to run your own mail server.
If it was crypto-related the argument would be Think.if the children™, since it’s email the excuse is spam.
Thomas DouwesI know a there are a lot of issues with self-hosting email, but I just don’t thing this is one of them. First, it probably won’t affect a self-hosted server anyway unless you send a lot of emails, this requirement is only for servers sending 5,000 messages daily to Gmail. And the requirements are not that harsh, it’s a couple DNS records and a DKIM signing daemon, and if you are using a pre-build email package like mailcow it’s probably already doing it.
