You had to dig deep to get a news from 2021. and still, private doesn‘t mean anonymous, idk why everyone relates the both.
And still, no news here, Proton explained this case several times and they‘ve been pretty transparent.
The only data we could provide (in response to a binding Swiss legal order), was the user's recovery email address, which the user added himself, and is optional to begin with.
Unfortunately, said user also used that recovery address to create a Twitter account, and Twitter turned over his phone number and IP address. So probably not the smartest move if you want to threaten public officials.
Coincidentally, this case again proves that Proton Mail's encryption cannot be bypassed by law enforcement.
They don’t offer unlimited addresses for your own domain. And I kinda rely on that to route different registrations around. Don’t even need unlimited mailboxes, just the ability to use patterns and direct assignments to route mail to a few mailboxes.
They semi-recently bought Simple Login which you can provide with your own domain. That does allow you to create unlimited addresses and they'll all be forwarded to the inbox of your choice. Can also disable any addresses when you no longer want them.
From what I've gathered, you can simulate unlimited addresses for your domain by setting up a catch-all. To reply from a certain catch-all'd address, you need to create an address for that name.
I wonder if you could do that via API; creating and deleting the address just for the moment where you're sending the reply.
It's strange to me that they don't offer unlimited domains. I guess it's to discourage business users from using the cheap email plan intended for individuals? That one doesn't have user management, so that doesn't really make sense either.
They support catch-all addresses. So essentially any email @your.TLD will work. I use this and it works perfectly. Nowadays I also use the included simplelogin address if I don't want to disclose even my domain.
