Before you start
- Proton Mail does not offer IMAP directly. You need the Proton Mail Bridge app running on your Mac.
- Proton Mail Bridge is only available on paid Proton Mail plans.
- Bridge runs on your own computer at 127.0.0.1. 1143 and 1025 are the default ports; Bridge shows the exact values.
