Nice, the more stand alone non corporate email providers the better. You have it on a good host. I've never tried to email from their CIDR blocks, curious how it works out.

Excellent! Simple and functional UI, Thank you for this.

I'd like to know more about the operator, besides them being from USA. Having the data in Iceland sounds great, but we should be wary of any new service designed specifically to attract confidential conversations.

I know it's in it's infancy here, but if it's a solo passion project I'd consider open-sourcing it so the E2EE can be verified. If you plan on launching this as a monetized project of some sort, I, as a potential customer, would suffice for audits but I'm sure they can get pricey. I'll give it a shot either way, just my two cents

I thought this was going to be related to the excellent libghostty based iOS terminal client: https://github.com/kitknox/rootshell

Another company tried the Iceland root, and after growing steadily and without reporting issues (at least I never saw anything reported) just shut down one day.

You defeated https://www.emailprivacytester.com straight off. Which is more than most new email services. You seem to be relying on CSP entirely for this, but it works.

I’m never hosting or dealing with any companies in Iceland. I had a run in with a hosting company there who was DoS attacking us from compromised nodes. I emailed them and they told me to get a letter from a local lawyer telling them to stop and they’ll look at it. In the end we contacted our DC provider and they dumped all traffic from their entire blocks. A year later same attitude from a different one hosting a web site for Covid misinformation which was against their own AUP.

> Key bundle missing — please try again I’m trying to create an account to test this service. I get this error message, what does it mean? Why is the error message so short to the point where I (the user) don’t know what to do next? Why can’t software developers learn how to communicate better with their non-tech users? And this is coming from someone with a 30+ years career in software engineering. edit: after hitting the button “I’ve saved my recovery phrase - continue” multiple times and getting the same repeated error message, it finally worked but then the API returned “error: Registration failed” . And at this point I give up. This is why many projects, even at Big Tech companies, fail: too much friction for new users, or too many features, or too many options to choose from.

Why is it called root shell?

Not to be confused with rootshell: macOS terminal emulator built with libghostty with powerful features https://news.ycombinator.com/item?id=48390029

Quick question for the author in case they are here > encryption key is derived from the password > One can use the passphrase in case password is lost What does this really means? is the password encrypted with these pass phrases instead of being hashed?

for a moment i thought it was rootshell.be - many many years ago they were giving away shell accounts, and teenager me used to have one for learning purposes (and also for the cool domain)

I find it very hard to trust any email service that claims to be E2EE without an audit by a reputable firm like Cure53 or Trail of Bits. I signed up to give it a brief test and immediately noticed that emails are returned from the server in plain text. This means that the emails are decrypted on the server, which defeats the entire purpose of E2EE. The encrypted email contents and metadata should be returned to the user and decrypted on the client. It's also painfully obvious that the entire thing is vibe-coded. While that in itself isn't an issue, it raises scrutiny. If the author doesn't have a full understanding of the code their LLM generates, some nasty bugs could be lurking. Not very promising.

I do not understand why anyone would want their email provider to be "E2EE". If I want end-to-end encryption then I will exchange public keys with the recipient.
nemothekid
What does E2EE mean here? If I send an email to someone using rootshell from gmail, doesn't rootshell get the email in plaintext?
gigel82
There is no such thing as E2EE email. You can encrypt your storage or some of the hops, but the plain-text email contents goes through between every layer, unless you're talking about PGP, or some similar scheme you built on top of the email protocol (where obviously both the sender and the recipient must participate).

It doesn’t work, upon registering, you get “key bundle missing - please try again”
