How do we know who's controlling the Lavabit domain?

Check whois database.

Also Ladar Levison twitter: https://twitter.com/kingladar

If he lost control of his domain, he will tweet about it.

I guess your point is that he is using Let's Encrypt instead of CA that would verify person or Lavabit LLC identity. In this case, it is not really an issue. If you are not going to check the cert manually every day, pinned Let's Encrypt cert is not way worse given that you have other means to verify ownership.

That's total nonsense.

> Search isn't possible

It absolutely is, in both theory and practice. The server stores an encrypted index, and the client walks it (requesting parts as needed). It's going to little slower, and a lot more complex but it's doable.

> If you lose your private key, we can't recover your email

This is a damn feature. I had my icloud account social engineered (someone walked into an apple store claiming to be me and they couldn't get their iphone syncing to "their account"). I'll never again trust another company with my private stuff.

> Spam checking on content isn't possible

This is probably your best point. It's definitely harder to do well

> To access mail on multiple devices, the private key needs to be shared securely between them

This is a non-issue. It can easily be derived from a password

Is there any person as trustworthy as Ladar Levison for a service like email or chat? To my knowledge, he is one of the few that has gone to the mat for his users.

The owner of Cock Mail / cock.li is at least completely realistic with what can be expected from an email provider. Goofy domain names aside, being completely frank about privacy and security realities is what you want.

Also search that only uses email titles is still at least 70% as useful as full title+body search. So I wouldn't count this as such a terrible non-feature of e2e encrypted email.

I think it's possible, just slower and more complex (like search) - and would have to occur upon unlocking your inbox.

A good way to regain and build trust with users would have been to acknowledge his previous mistakes. Then at least you could say "he's been around the block, done it wrong and learned how to do it right". Instead, he writes: "In August 2013, I was forced to make a difficult decision: violate the rights of the American people and my global customers or shut down. I chose Freedom." That isn't what happened. He chose t…

> The completely pointless escalation forced him to compromise all of his users

How has he compromised all of his users? The service was shut down and emails kept encrypted. Am I missing something?

Whatever did or didn't happen in the past, I for one am pleased to see another organisation attempting to make email more secure. Especially when governments have gone surveillance crazy. Goodluck Lavabit
