1. Allow users to generate separate SMTP credentials to enable secure third-party integration

   Note: This is a different request than the similar SMTP Token customization.

   Problem Statement

   Currently, Proton Mail (including Proton Bridge) uses the same authentication credentials for both receiving and sending email. This creates a security risk when integrating third-party services:

   Single Point of Failure: Any service with my credentials can send emails from my account
   No Safe-by-Design Option: Even if I instruct an AI agent not to send, there's no technical enforcement
   Least-Privilege Violation: Services that only need to read/process mail shouldn't have send capability
   

   Use Cases

   AI Email Assistants: Sort, prioritize, summarize incoming mail without send risk
   Automation Scripts: Process incoming mail for workflows (e.g., ticket creation, notifications)
   Third-Party Filters: Advanced spam filtering, categorization services
   Backup Solutions: Secure mail archiving without send capability
   

   Greatest security threat is AI agents. Handing the ability to read emails to an agent automatically allows it access to sending mail as well. AI agents should not be able to access SMTP and admin panels just with the credentials to read email.

   Quick test implementation opportunity: Implement it in Proton Mail Bridge first. This should be a relatively minor update without impacting the general Protonmail service.

2. Allow organizational admins to disable mail forwarding

   Currently, anyone within an organization could set up mail forwarding and send all their communications to an insecure email, essentially exfiltrating company data. As an organizational admin, I would like to disable this for security reasons. I think this setting could live near the 2fa/mfa settings so that as an admin, I can lock down this functionality.

4. Add right-click option to view received mail in a new window (browser).

   It would be helpful to be able to either right-click or double-click on messages in folders in order to have them occupy a different window or tab when using P Mail from a browser.

9. In the iOS Calender app, add the option to couple invites to different calendars.

   In the Proton Calendar iOS app, we're stuck with a meagre accept and view option in the case of an invitation by someone. We can only accept an invitation and add it to the default calendar. This requires us to 1) remember to 2) use another device to put the invitation in the 'correct' calendar.

   In the Proton Calendar webapp and in the (macOS) Proton Mail & Calendar app, I can couple an invite from someone else to any Calendar. This allows me to have a clear overview (different colors, different reminder settings) for both (different) clients and private meetings. I'm assuming that was a major reason behind this functionality.

   Please add the described functionality to the iOS Calendar app. These options make the difference between time-saving and time-consuming.

10. Copy email addresses for everyone on a calendar invite

    It is very hard to email everyone who is invited to a calendar event. Even if you cannot add the "reply to calendar invite" function, can you please at least make it easy to copy all the email addresses out? Right now, if you try to copy them and then paste them into an email "to" section, it gives me an error.

    Related to this, I can't copy-paste a list of emails from a spreadsheet into a calendar invite, which is extremely frustrating! Please fix the formatting so that I can add a bunch of emails to an invite quickly and easily.

11. WIRE App Integration with Proton Calender for automatic creation of meetings rooms

    User Story

    As a Proton and WIRE user
    i want to add a WIRE conference call easily / automated to my calendar event invitations
    so that i don`t need to manually open WireApp to set up a conferencing call and copy the link manually to the calendar event

    Rationale
    As a proton user i already value privacy and data security.

    (1) Since a couple of month Proton offers an own encrypted conferencing tool. But its only web based and does not go beyond conferencing - messaging outside of a conference is not in scope. WIRE would close both gaps.

    (2) At the same PROTON offers a whole ecosystem of privacy tools. That is a general problem for users. If you use multiple PROTON services at the same time (all eggs in one bag) you are done in case of a breach on provider level.

    It would be great to reduce the accumulated risk as a proton user and move the conferencing part to WIRE.

    Additional information
    - Proton Calendar already has a zoom / proton meet integration that works fine. Just add your service in collaboration with Proton to that list.
    - The invitation e-mail should include the recipients as WIRE guests by default.
    - There should be a function to add existing WIRE user account name ( @username ) to recipients

    Please see the corresponding feature request at WIRE:
    https://support.wire.com/hc/en-us/community/posts/35844805633949-Integration-with-Proton-Calendar

    Thank you.

13. Same event in multiple calendars

    I have the problem that I need to share the same event with multiple different groups of people.
    For example, I need to share the dates of my firefighting drills with my office and my partner and sometimes even with my sport club. It would be amazing if it would be possible to elect multiple calenders when creating a new even or edit an existing one. Maybe there could even be some kind of "logical calendar" as shorthand to select a specific predefined set of calenders.

14. Remove default connexion from old email adress

    Hello,
    When I created my proton email adress, I chose to connect it to my old gmail adress because I was originally thinking to suppress it. In the end I'd rather keep the old one for newsletter and promotional stuff, but I am not allowed to block the numerous messages I get from the gmail adress on my proton one, which is quite annoying.
    Can we find a way to change this feature or should I create a new proton adress?
    Thank you for considering this change or any advice.
    Best,
    Julia

16. make the invitation email for calendar events optional

    The email is currently mandatory.

    There is at least one use case when the email is not desiderable:

    I receive a Google Meet link with date and time by message in a Telegram DM or whatever.

    The meeting is agreed upon and confirmed by both.

    That person already has the event on his Google Calendar.

    I want to set it on my Proton Calendar with the counterparty email as a reference for myself, but I would rather not send a duplicate confirmation email.

17. Time-tracking Calendar Integration

    One missing feature from the Proton Suite is a Time-tracking layer integrated in the Calendar app.

    It would be a handy feature to toogle on/off alongside your planned schedule, in order to track the real time invested in your projects, get records and overviews, and be able to learn from them and improve your workflow. All with the same level of privacy and encryption of the other features.

    Right now Proton users still depend on external apps to track their time, which don't integrate in the Proton ecosystem nor offer the same kind of data security. More on the contrary, multiplatform time-tracking sync apps are full of commercial trackers (pun very much intended) alongside security bugs.

    Also, If the Calendar app is indeed planning to allow to run it locally and asynchronized as an option, the Time-tracking layer could work the same way for those who don't want/need online sync between devices.

    I think there's a niche in the market for such (encrypted) feature, and it would be a point of attention for (small) businesses and independent entrepreneurs, while weighting on the idea of the Proton Suite above others.

19. (Current) Critical Security Vulnerability: Missing Default-Deny Policy - Why Whitelists Fail Against Zero-Click Exploits (State Trojans)

    (Current Text) April 26, 2026
    Dear Proton Team,

    Currently, Proton Mail under (Filters) "Blocked and Allowed Senders Lists" offers only a whitelist as a positive exception in a system that standardly accepts everything ("Default-Allow"). The "Allow" function serves merely to move important emails back from the Spam folder to the Inbox; it does not prevent the receipt of emails from other domains. The "Block" function serves only to block known, malicious senders.

    The fundamental security problem is that for users who need to protect themselves against Zero-Click Exploits (e.g., advanced state trojans like Pegasus or similar spyware), this "Default-Allow" model is fundamentally insufficient and dangerous. An attacker can register thousands of domains or use hacked servers to send malicious emails. A "Block" list can never cover all future, unknown attackers; as soon as a new, malicious domain is created, it is not on the list, and the email is accepted. Furthermore, as long as the Proton server accepts every connection from an unknown domain (even if it is later moved to Spam), there is a critical risk that a Zero-Click Exploit could be executed during the processing phase, such as rendering images, parsing metadata, or analyzing attachments. The malicious code does not even need the user to open it; it can compromise the email client or server infrastructure as soon as the data touches the server. Many users mistakenly believe that an "Allow" list automatically blocks everything else. Technically, this is not the case. The current list is merely a filter ensuring that certain emails do not land in Spam, not a firewall that cuts off access for everyone else.

    I therefore demand the introduction of a separate, explicit setting "Allow Only Permitted Senders" that fulfills the following technical requirements. First, the whitelist must offer flexible granularity by supporting both individual email addresses and entire domains. This allows users to define permitted senders with two distinct levels of granularity to balance maximum security with practical usability. Individual email addresses are essential for high-security scenarios where only a specific person is trusted (e.g., john.doe@company.com); this prevents access even if other accounts within the same domain are compromised. Entire domains, on the other hand, serve for the efficient management of trusted organizations or partners (e.g., @trusted-partner.com) and allow all current and future senders from that domain without manual maintenance. The system must evaluate incoming mail against both lists, with a specific address rule taking precedence over a general domain rule if conflicts arise.

    Second, server-side rejection at the TCP/SMTP level is required. The server must immediately reject the connection before any data transfer if the sender is not explicitly on the whitelist. This requires validation already during the SMTP handshake, ideally immediately after the EHLO/HELO command or at the latest before the MAIL FROM command. If the sender is not allowed, the server must immediately terminate the TCP connection or return an SMTP error code (e.g., 550 Access Denied or 554 Transaction Failed) before the actual email data transfer (DATA command) begins. No data packets containing potential exploits may be received; the server must not buffer or analyze the email content even temporarily if the sender is not on the list. The connection must be severed at the entrance so that no data packet containing a potential exploit is received by the server infrastructure.

    Third, full user control must be guaranteed. Users must be given the opportunity to completely close their digital gate ("Air-Gap" principle for email) without relying on infinite and never-complete blocklists. The responsibility for maintaining the whitelist lies with the user; this is the principle of every high-security system.

    Proton advertises worldwide with "maximum protection" and "end-to-end encryption." Yet, without a "Default-Deny" option that supports both address and domain whitelisting, the door remains physically open to unknown attackers. With this function, Proton would be the only commercial email provider enabling users to protect themselves against state surveillance and zero-day attacks through strict perimeter security. For journalists, whistleblowers, and activists, this is not an optional comfort feature, but a matter of survival. The ability to whitelist entire domains simplifies communication with teams, while the option to whitelist single addresses ensures precision against targeted attacks.

    Please evaluate this request for technical feasibility and prioritize its integration into the roadmap for security updates. Proton should offer this choice to substantiate its position as the world's safest provider.

    Thank you for your work on a safer internet.

20. Strike agenda items

    When deleting an event in the Proton Calendar, I still want to be reminded that it was there originally. Is it possible to offer two kinds of delete:
    (A) strike through the event (so it is still visible in the calendar, but now the title is in strike through), or
    (B) permanently delete the event?
