[Proton Mail] Unable to connect to Proton Mail via IMAP despite Proton Mail Bridge running

Extension

https://www.raycast.com/NormC/proton-mail

Raycast Version

2.1.2.0

OS Version

macOS 26.6.2

Description

I am unable to configure the Proton Mail extension for IMAP in Raycast.

Proton Mail Bridge is open and running, and I have verified that the username and password are correct. I tried the available encryption options, including SSL and STARTTLS. However, the extension cannot establish a connection to the IMAP server.

Steps To Reproduce

1. Open Proton Mail Bridge on macOS and make sure it is running.
2. Open Raycast and launch the Proton Mail extension.
3. Enter the IMAP connection details provided by Proton Mail Bridge:
   • Host: 127.0.0.1
   • Username: [Bridge-generated username]
   • Password: [Bridge-generated password]
   • Port: [port shown in Proton Mail Bridge]
4. Try the available encryption options, including SSL and STARTTLS.
5. Save the configuration and try to browse or search the mailbox.
6. The extension fails to connect to the IMAP server.

I have also restarted both Proton Mail Bridge and Raycast and recreated the IMAP configuration, but the problem persists

Current Behaviour

The extension cannot connect to Proton Mail Bridge via IMAP.

Proton Mail Bridge is open and running, and I have checked that the username and password are the credentials generated by Bridge. I have also tried both SSL/TLS and STARTTLS, but neither option works.

The extension either reports a connection error and does not load any messages:

IMAP connection failed: Command failed. Please verify:
- Proton Mail Bridge is running
- Host: 127.0.0.1
- Port: 1143
- Username and password are correct (use the Bridge password, not the Proton account password)



### Expected Behaviour

The extension should connect to the local IMAP server provided by Proton Mail Bridge and allow me to browse and search my Proton Mail messages from Raycast.

Start with the Proton Mail extension linked in the issue and reproduce the IMAP setup against Proton Mail Bridge using the reported host, port, credentials, and encryption options. Compare the connection error with the Bridge configuration, then verify that the extension can browse and search messages after the fix.
