1. Proton Mail: Comprehensive Detailed Proposal

   1. Full End-to-End Encryption for All Mail Services Creation & Implementation:

   Conduct a thorough security audit of Proton Mail modules to identify any unencrypted data at rest or in transit.

   Use a centralized Key Management System (KMS) leveraging Hardware Security Modules (HSMs) for secure key storage.

   Generate user key pairs (RSA-4096 or ECC Curve25519) locally on client devices; private keys never leave the device unencrypted.

   Encrypt all emails, attachments, and metadata with AES-256-GCM symmetric encryption.

   Use OpenPGP (RSA-4096) and ECC for cross-platform compatibility and mobile efficiency.

   Publish detailed technical whitepapers including encryption flowcharts, key derivation functions (Argon2id, PBKDF2), and zero-knowledge proofs to ensure transparency.

   Expected Benefits:

   Zero-access guarantee: Proton servers never hold decrypted user data.

   Transparency and trust through published algorithms and architecture.

   Future-proof security with post-quantum cryptography (CRYSTALS-Kyber, CRYSTALS-Dilithium).

   1. IMAP/SMTP Support for Free Accounts via Proton Mail Bridge Creation & Implementation:

   Remove IMAP/SMTP restrictions for free-tier users.

   Provide downloadable Proton Mail Bridge clients for Windows, macOS, and Linux.

   Enforce secure connections using TLS 1.3, HSTS, and certificate pinning.

   Use OAuth 2.0 with Proof Key for Code Exchange (PKCE) and short-lived tokens for authentication.

   Offer detailed step-by-step setup guides and video tutorials for popular email clients (Thunderbird, Outlook).

   Expected Benefits:

   Easier migration from legacy email providers.

   Increased user retention and satisfaction.

   Maintained end-to-end encryption even with third-party clients.

   1. Enhanced Account Security Features Support hardware security keys (YubiKey, SoloKey) and biometric authentication (TouchID, FaceID, Windows Hello).

   Implement adaptive multi-factor authentication triggered by risk factors (new device, unusual location).

   Provide detailed login and device activity logs with options to revoke sessions remotely.

   1. Alias and Permission Management Allow creation of multiple aliases with one-time keys to mask primary addresses.

   Implement OAuth 2.0 scopes for app permissions (mail.read, mail.send, contacts.read).

   Provide users with an app permission dashboard to monitor and revoke third-party access.

   1. Automatic Email Translation with Privacy Preservation Integrate client-side or hybrid translation engines (DeepL API or proprietary models).

   Encrypt email content chunks before sending to translation service; decrypt results client-side.

   Support major languages including Ukrainian, Korean, Japanese, and European languages.

   Add a “Translate” button in the email interface preserving end-to-end encryption.

   1. Improved Search Capabilities Develop client-side encrypted indexing for fast, privacy-preserving search.

   Support advanced filters: boolean operators, date ranges, sender/recipient, attachment-only searches.

   1. User Education and Support Provide interactive tutorials on encryption setup, alias management, and security best practices.

   Expand FAQ, community forums, and direct support channels.

2. Bridge for old computer such PPC Mac

   A lot of local activists who are using protonmail for fight against dictatorships and are still using old platforms to design posters, banners and staff like this are using old Mac computer with PPC. I know some gay communities in Minsk and other Burmese artists with old computers who will love to see such implementation. Sometimes, we, the occidental people forget that a computer is registered for governments (like a weapon in EU) so to let know the dictators that you have a computer is dangerous (like in Algeria or Morocco). This activists has old computers to generate posters and staff like this. Let´s help them and bring them a bridge. If not they are risking their lives in cibercoffes.

   Thanks!

   As much as we would like to support as many platforms as possible, our primary concern needs to be security. We cannot recommend to use our software on operating systems with known security issues; the older the system, the more such issues exisit.

   Bridge is not designed to be used on mobile and we have no plans to change that. We recommend using our native iOS app.

4. VPN builtin into Protonmail Bridge

   I'm paid user, and I can't have "always-on" ProtonVPN on my computer, but on the other side, I would like to have Proton mail in my favorite email client always updated.
   To solve this issue, it would be great if you add a feature to establish a VPN connection within ProtonMail Bridge

   Since VPN and Bridge are two separate products with very different functionality, we won't be integrating them together at this stage.

   This is not possible, as would have to be implemented within the third party client, over which we have no control.

    At this time, there is not sufficient demand, or sufficient resources, to justify developing for Windows Phone.

    In order to best direct our resources, we are going to leave development of a Windows phone ProtonMail app to the user community, and we will support any open source initiative to accomplish this.

15. I would be interested in paying for $25 per YEAR (not month) for Unlimited domains & UNLIMITED addresses.

    I would be interested in paying $25/YEAR for Unlimited domains and addresses.

    I use catch-all and have probably 5 trillion trillion trillion possibilities and am not interested in paying MONEY to use an email ONCE.

    I want to be able to RECEIVE AND SEND from ALL domains and all email aliases, unlimited possibilities for each domain, and I have a lot of domains.

    PRESENTLY I GET ALL OF THIS 100% FOR FREE WITH GOOGLE APPS and I am unlimited grandfathered in forever. It allows 100 maximum SEND FROM emails, when I use them all I will just remove some I am not using to add more at any time. It allows 5 POP3 emails with 100 "send from" emails.

    So I can receive to unlimited number of emails FREE FOREVER with my google apps account which is the #1 most functional email on the internet today.

    My google apps account has 15GB of storage for free, but I never used this much. In fact over 10 years I only used 8GB. You should allow UNLIMITED everything except for storage. I can see having to pay more for high storage, but the rest is just SOFTWARE, there is zero expense to you so I should not have to pay for what costs you nothing.

    Summary WHAT I HAVE NOW:
    Google apps:
    * Cost: FREE - grandfathered forever.
    * UNLIMITED domains (INFINITE to receive mail to same inbox.)
    * 100 "send mail as" accounts at one time (can delete and add whenever I want)
    * 5 POP3 accounts (would like more, but at least this many)
    * 15GB storage
    REQUIRED FEATURES THAT IS HAS ALREADY IN MY FREE GOOGLE APPS ACCOUNT:
    * dark theme
    * delayed send feature (under "labs")
    * every send mail as can have its own html-based signature
    * robust filters
    * best search filter
    * best folders/archive capabilities
    * canned responses

    The only reason to leave gmail is because I want more privacy. But I do NOT want it for hundreds of dollars per year, it's just not worth it especially when I already have this for free. But I would pay TWENTY FIVE dollars per YEAR for the same or better benefits as google apps, just for the benefit of privacy.

    I will never use Protonmail despite having a protonmail account from the very beginning, until I can use it as an affordable replacement to google apps. FOR YOUR CURRENT ABSURD MONTHLY RATE I COULD INVEST THAT INTO SOMETHING ELSE AND IT STILL ISN'T EVEN CLOSE TO UNLIMITED FOR MY USAGE EVEN THOUGH I HAVE VERY SMALL STORAGE USAGE, SO IT'S PRESENTLY A TOTAL WASTE AND USELESS.

    You could probably have 1 million new users overnight if you offered a google apps replacement for $25 per year with the same features as I showed above.

    I would have already paid for the last 2-3 years if you had this option.
    I would never use it when i have to pay for individual addresses, especially since I already have it all for free in Google Apps.

    Everyone is looking to leave google, and yours would be the best google replacement except for your PROHIBITIVE COST, AND PRICING STRUCTURE.ore restless and want to leave google. BUT NOT FOR HUNDREDS PER YEAR. $40 per YEAR would be the MAX per year for UNLIMITED everything, although even at $40 I would be reluctant to pay that and may still not sign up because of this high cost per year of $40. But for $25 per year I would jump immediately for this unlimited plan.

    I would be interested in paying $25/YEAR for Unlimited domains and addresses.

    I use catch-all and have probably 5 trillion trillion trillion possibilities and am not interested in paying MONEY to use an email ONCE.

    I want to be able to RECEIVE AND SEND from ALL domains and all email aliases, unlimited possibilities for each domain, and I have a lot of domains.

    We will review our planes and try to make adjustments that will enable more users to afford ProtonMail.

    However, this request is impossible to honour due to the way our business model is developed.

    Contrary to Google, ProtonMail is not reading its users’ emails for advertising purposes, it does not serve ads, and it does not abuse personal data.

    As a result, our only income to maintain and develop the service comes from our users, and not from the advertising market.

    Google can offer all of this for free because you are not paying for the product with money, but with your privacy.

16. I am new to Proton - email domain question.........

    Please direct all questions to our support page: protonmail.com/support. You will find a way to contact us directly at the bottom of this page.

    ProtonMail does not support other email addresses at this time. ProtonMail can only be used with protonmail.com email addresses.

17. encrypted / unencrypted icons

    Can you make the grey locked icon and the black unencrypted icon more easily distinguishable?

    Maybe leave the grey one as is, and for the unencrypted icon, have the image shown with the lock's shackle swung out and away from the body of the lock?

    Unfortunately, due to the cost of custom domains we are unable to offer this service without charging for it. You can use your custom domain with your ProtonMail account by upgrading your account: https://protonmail.com/support/knowledge-base/protonmail-plus/.

    IMAP will be an option feature we will be adding in the future. This feature will maintain the end-to-end encryption ProtonMail is built on.

20. Exclusive Mode Receive Messages Only From ProtonMail

    Exclusively receive messages from friends and invited contacts from ProtonMail to ProtonMail from the contact list. Messages from ProtonMail domain will be highlighted or feature an icon when not in Exclusive Mode. When using Exclusive Mode email senders outside of the ProtonMail domain will receive an automated email message denying their request for email communication.
