2. Add Advanced Sieve Extensions: Mailbox, Notifications, Body Filtering...

   Proton Mail's Sieve implementation is missing several powerful RFC-standard extensions that would unlock advanced email automation.

   Here are the key missing features: Mailbox Creation and Checking (RFC5490, RFC9042) - Automatically create folders and organize emails by sender domain without manual setup.

   Notifications (RFC5435/RFC5436) - Send SMS or email notifications when specific emails arrive instead of just filing them.

   Body Content Filtering (RFC5173) - Filter emails based on message body content, not just headers, for smarter spam detection.

   Edit Headers (RFC5293) - Modify or add custom headers to emails as they arrive.

   File Carbon Copy (RFC8580) - Keep automatic copies of filtered emails in specific folders for compliance or backup.

   Calendar Processing (RFC9671) - Automatically handle calendar invitations and ICALENDAR attachments.

3. S/MIME signature validation support for e-mail clients via Proton Bridge

   Please add support, that an e-mail client connected via Proton Bridge is able to validate S/MIME signature.

   Reason: Banks, delivery services, public authorities, etc. use S/MIME signed e-mails to prove that an e-mail is genuine. This helps fighting fraud, fishing and other criminal activites.

   Context: Currently, S/MIME signature cannot be validate in Proton Mail. A validation with an e-mail client connected via Proton Bridge cannot validate an S/MIME signature because Proton modifies e-mail headers that are essential for a successful S/MIME signature validation.

   The posted idea "S/Mime Support" at https://protonmail.uservoice.com/forums/284483-proton-mail-calendar/suggestions/16574134-s-mime-support requests for much more: a full S/MIME implementation.Although full S/MIME support would be great, in my opinion, the most important part is to be able to validate S/MIME signatures.

5. Edit public holidays

   Please consider allowing one to edit public holidays that are imported for a particular country, e.g. delete a regional public holiday that is not relevant to the user because they live in a different part of the country. Currently you cannot delete any public holidays. It will help to reduce calendar clutter. Thank you for considering!

6. Proton Mail and Calendar Bridge for iOS

   My work HIPAA compliant encrypted email through Microsoft exchange works with apple's mail and calendar apps, so I don't necessarily understand why that couldn't be the same for Proton, especially if it just works through a device management profile like how desktop proton bridge works for the apple mail app.

   I am not asking this because I think there's something inherently wrong with the Proton mobile apps, I am asking because I would like one app where I can view all of my inboxes together (same for calendar). I personally have my personal proton mail inboxes as well as Microsoft exchange inboxes for work and for school, and a lesser used iCloud email address, and a google account created with my proton mail email so that family who uses Google Calendar can share their google calendars with me without having to make their calendars public. I prefer the apple mail and calendar apps because they allow me to view all of these calendars and inboxes together, regrettably except my proton mail account.

7. Feature Request: Respect DMARC "p=reject" Policy for Custom Domains

   I'm writing to suggest an improvement to Proton Mail's handling of DMARC policies. Currently, when an incoming email fails DMARC validation for a domain with a p=reject policy, Proton Mail always delivers it to the Spam folder instead of rejecting it at the SMTP level.

   While I understand this "soft" approach prevents legit mail loss due to misconfiguration (as permitted by RFC 7489 Section 6), it also diminishes the security value of a "Reject" policy for domain owners who want to strictly prevent spoofing.

   Proposed Phased Implementation:

   Phase 1 (Internal Custom Domains): Exclusively allow Proton Mail Custom Domain From Addresses to apply their DMARC Reject Policy (if applicable). Since these users manage their own DNS records, they expect higher security standards. By rejecting failed emails at the gateway, you can provide them with the precise protection they've configured.

   Benefit: This minimizes the impact on general "mailing list" senders while significantly boosting security for Proton's paid users.

   Phase 2 (Advanced): Provide a toggle in one of the settings page allowing the paid users (or all users) to opt-in to "Strict DMARC Reject Policy Enforcement."

   Why this matters: True DMARC rejection prevents sensitive "Business Email Compromise" (BEC) attacks from ever reaching the user's mailbox. Forcing these into the Spam folder still leaves the user vulnerable to social engineering if they check their Junk mail.

   As a privacy and security-focused service, Proton Mail should be the ideal platform to lead the way in honoring domain owners' explicit security intents.

8. Advanced PGP Key Management for Proton Mail Users

   Description

   Currently, Proton Mail allows users to manually add PGP public keys to external addresses only.
   
   This creates several limitations for users with more complex encryption setups or personal key hierarchies.

   ---

   Problem 1: Limited Manual Control

   Users cannot manually specify whether an email should be:

   • Signed only
     
   • Encrypted only
     
   • Signed and encrypted

   Instead, Proton Mail enforces a fixed default behavior per contact.
   
   If a user wishes to change how messages are sent, they must manually adjust the contact’s encryption settings each time.
   
   This slows down workflows and complicates secure communication.

   ---

   Problem 2: External Keys for Proton Addresses

   Some Proton users maintain their own personal PGP key pairs associated with their Proton-hosted email addresses (for example, to preserve local control or maintain a separate trust model).

   However, when receiving messages from other Proton Mail users, Proton’s system automatically forces the use of the Proton-managed encryption keys, preventing users from:

   • Assigning their external public key to that same Proton address, or
     
   • Choosing an alternative key manually for encryption/signing.

   This limitation breaks compatibility with privacy-focused setups or air-gapped key workflows.

   ---

   Problem 3: Security Tradeoff

   The only workaround — uploading the external private key to Proton — undermines the purpose of maintaining an offline or self-controlled key.
   
   Even if Proton’s storage is zero-access, this still requires trusting Proton’s infrastructure with a key that ideally should never leave local custody.

   ---

   Suggested Enhancements

   1. Manual Key Override
      
      Allow users to override key selection on a per-message basis, including:

      • “Sign only”
      • “Encrypt only”
      • “Sign and encrypt”
      • “Send plaintext”

   2. Custom Key Mapping for Proton Addresses
      
      Enable assigning an external public key to a Proton-hosted address, even when interacting with another Proton user.

   3. Per-Message Key Selection UI
      
      Add an “Advanced” or “PGP Options” dropdown when composing a message to select signing/encryption behavior or which key to use (similar to Thunderbird or GPGMail).

   ---

   Rationale

   These improvements would benefit advanced users who manage their own key infrastructure or use Proton as part of a broader privacy toolchain.
   
   They enhance flexibility and control without compromising usability or Proton’s secure defaults for non-technical users.

10. Select all emalis matching a search

    Again... seems like this would be on a "required for day one" list but - we need the ability to perform a search and select all matching results. Currently there is a 'first page' or 'all' on a Folder and Label level - but it needs to be more granular - while still allowing to select more than 50 results.

11. export event as *.ics (also recurring event)

    Propose to allow export event as *.ics file. Quite often is needed to create an event and send other people that event as calendar event, which can be imported regardless of used calendar. For such purposes, the *.ics event format is the best. Please allow export event as it is: either one or recurring event. Thank you!

12. Choose which alias can log in to Proton

    Hello Outlook.com now is accepting to choose what alias can be used to login on account to improve security.

    Why Proton mail dont do the same thing? with this we are protected from botnets(credential stuffing or brute force), because we can create a alias and dont share the username with anyone.

14. Add multiple ways to sort emails.

    I originally wanted to ask that we be able to sort our Inbox by tag/label. I did see that idea, but also saw requests to sort by star/no star and sender. So I wanted to combine these into a single improvement - to be able to sort the inbox by any column. Being able to do this, helps improve productivity. I would like to be able to see the emails I consider most important to follow up at the top, for example. It can also be valuable to see all the emails from a particular sender or under a specific label grouped together.

18. Added a simple option to make emails unreadable by AI

    I heard about a great tool on GitHub that simply makes text unreadable by AI: gibberify by Will Patti (wdpatti).
    The tool is available at this address: https://github.com/GeneploreAI/gibberifier
    I think it would be great to integrate this into Proton Mail so that text can be made unreadable with a single click.
