That policy of theirs has existed for a long time now. It's a really odd one at that.
They also don't enforce DMARC, nor do DKIM. It's stuck nearly four decades in the past.

That's Germany in a nutshell.
2026 - 40 = 1986 was right before more mainstream internet adoption. Yep checks out, Germany today.
Were the trains running on time in Germany back then? They certainly were 20 years ago, so I assume they were in the 80's.
Maybe "strictly worse than 40 years ago"?
Microsoft has a similar policy on their consumer domains though. If they have not received mail from you for a month or so you are insta blocked. It's infuriating for personal mail server owners.
Microsoft and google seems hellbent on destroying classical email, by doing this crap. Their interoperability is also pretty bad.
Yes. It's the last phase of embrace, extend, extinguish. Typical big tech move.
When I ran my own mail server Microsoft was the only company I encountered that would black hole my messages - no SMTP error for my own server to bounce back to me, no bounce back from their server, nothing. I vaguely recall having to do a dance with them a few times to fix this and the last time I tried I received no response. I don't frequently interact with Office 365 users so this didn't matter much to me.
I did end up later moving to Proton primarily out of laziness. I thought these issues would be a thing of the past until I applied to work at a company that administered their own Exchange server that also black holed my messages from Proton's servers. Their reasoning? "We geo-block Switzerland for security reasons." Needless to say I turned them down.
Oh when I ran my own mailserver I did get SMTP errors back.
Every month or so I had this issue and I had to contact them through a form somewhere and I would get emails back from someone in india who reset my 'reputation'. They have some stupid made-up reputation system which means they need to see significant volume from you that is not marked as spam for them to accept your mailserver.
And yeah proton has similar issues. A lot of companies blackhole even confirmation emails there. So you can't confirm accounts with a proton email and they give zero indication as to why. Tinder and the internet archive (archive.org) come to mind.
