Proton Mail Bridge
Proton Mail Bridge runs a local IMAP/SMTP service that lets traditional mail clients access a Proton mailbox. This LXC runs Bridge headless and forwards IMAP/SMTP to the LAN using systemd socket activation (systemd-socket-proxyd).
Proton Mail Bridge
Installation
Default install:
1
bash -c "$(curl -fsSL https://raw.githubusercontent.com/community-scripts/ProxmoxVE/main/ct/protonmail-bridge.sh)"
Notes
After install, run protonmailbridge-configure inside the container for first-time setup.
LAN forwarding (container IP): IMAP 143 -> 127.0.0.1:1143, SMTP 587 -> 127.0.0.1:1025.
You can later use protonmailbridge-configure to temporarily stop the service and enter the Bridge CLI.
