Proton Mail Bridge
Review the coming-soon Proton Mail option and its planned Bridge values.
Status: Coming soon. Proton Mail cannot be selected in the public setup flow.

The current public UI cannot test or save a Proton Mail account. The planned option is based on Proton Mail Bridge, which exposes local IMAP and SMTP endpoints instead of a public mailbox endpoint.
Planned Bridge reference
| Setting | Value |
|---|---|
| IMAP host | 127.0.0.1 |
| IMAP port | 1143 |
| IMAP encryption | STARTTLS |
| SMTP host | 127.0.0.1 |
| SMTP port | 1025 |
| SMTP encryption | STARTTLS |
These are planned defaults only. Bridge support is not active in the public setup flow.
