And it’s also way to spread the ProtonMail idea to thousands of implementations of secure e-mail services in the world, which the BigBrother will have hard time to cope with. Of course it will be long run and of course, after new standard eventually published, there will be yet needed time for developers of e-mail clients to implement it, but, from long-term view, it’s the best way. Rather then developing the new protocol completely separately, I think best way would be to try to get in touch with IMAP working group of IETF and help to incorporate the necessary features into new version of IMAP. So, in principle, there is needed to design new standard protocol like IMAP, but with ability to deal with encrypted inboxes. Problem is, that IMAP, as is currently, is not designed to deal with encrypted inboxes. It would definitely increase usability of Protonmail, to have access to Protonmail inbox from native mail clients, by protocol like IMAP over SSL. We do not offer POP3 support, but ProtonMail Bridge downloads all your emails into your email client, and you can export them from there. ProtonMail Bridge uses the SMTP and IMAP protocols. To use ProtonMail Bridge, you need any paid ProtonMail plan.

You can download the app, find answers to frequently asked questions and get full support on the ProtonMail Bridge homepage. ProtonMail Bridge is available on macOS, Windows, and Linux. ProtonMail Bridge also allows you to import emails into your ProtonMail account from other email accounts connected to the same client, as well as run full-text searches of your ProtonMail emails. It allows you to fully integrate your ProtonMail account with most clients that support IMAP and SMTP protocols, with official support for Microsoft Outlook, Mozilla Thunderbird and Apple Mail. ProtonMail Bridge is an application that seamlessly encrypts and decrypts your mail as it enters and leaves your computer.
