Mailpile VS ProtonMail Web Client

Have a look at mailpile if you are after a web interface; or, the ever-dependable Thunderbird if you are fine with a desktop application.

mailpile seems good, but I would encripted things and besides this it is well mantained? The dockerfile here is old https://github.com/mailpile/Mailpile. By the way I tested a container, this rroemhild/mailpile, and it seems easy and with a good interface.

Mailpile supports theming. https://github.com/mailpile/Mailpile/wiki/Themes

Take a look at Mailpile.

Mailpile.is comes to mind. Their Twitter account is inactive since 2018, but they did fix some things on Github in November of 2020: https://github.com/mailpile/Mailpile/

> Email is not decentralized. It relies on the central authority of domain registries.

By that definition, almost every chat app is centralized, especially if you include the step of downloading it over HTTPS. In any case, it would be possible to further enhance email using something like SMTorP so that .onion addresses are used instead.[0]

> And then if you do decide that whatever encryption scheme you've chosen is right for you, there's no guarantee any significant mass of people supports it.

The same is true of any system which is proposed as an alternative to email. Admittedly it will be difficult for a UI to convey the security properties of messages when you are interacting with users whose email clients don't support the recommended extensions, but there is always the risk that a recipient will copy-paste the plaintext of your securely sent message into an unsecured channel.

For PC : Thunderbird or Mailpile

The source code is here https://github.com/ProtonMail/WebClients

> Finally, in keeping with our long track record of transparency, Proton Pass is open source so anyone can review and verify our security architecture

They sure do enjoy writing that sentence without including any hyperlinks. This (https://github.com/ProtonMail/WebClients/tree/main/applicati...) appears to be the browser extension and https://github.com/ProtonMail/WebClients/tree/main/packages/... appears to look like the backend referenced in the extension's readme, but that directory's readme is zero bytes so (shrug)

Fork the frontend and make your own lightweight option

PS: I hope that we selfhosters will have a modern, efficient, easy to use mail suite one day with modern features like JMAP, good self-learning spam integration, automated checks and validations for SPF/DMARC/DKIM or whether the IP/host suddenly appears in a blocklist and integrated encryption at rest for emails. Something that isn't 30 services in a container image, with 30 different configuration styles. Maybe even with an API integrated that's compatible to the ProtonMail frontend (like the neutron server once intended to be). Anyway, I'm sorry for dreaming. ;)

And if you want to customize it further you can use Stylus to add custom CSS, Tampermonkey to add JS, or even modify the whole thing yourself from source (if you run it locally it syncs with your actual account).

There are lots of useful End to end encrypted webapps such as Protonmail, cryptpad, cryptee and many others. And part of why we trust them is that the client side code is open source, so we can see that end to end encryption is really going on and is really secure. Its impossible to verify what code they are running in their server, but if the data we send them is already encrypted we can rest easy.
