Proton Bridge Email (age-encrypted)

Authored by Anis Afifi.

Use Proton Mail Bridge for local SMTP/IMAP and keep credentials encrypted at rest with age.

What this skill provides

  • •A minimal SMTP sender: scripts/send_email.py
  • •A helper to encrypt the Bridge env file: scripts/encrypt_env.sh
  • •Setup notes: references/proton-bridge-setup.md

Expected local secret location

This skill assumes the encrypted env file is at:

  • •~/openclaw/secrets/proton.env.age

And your age identity is at:

  • •~/.config/age/keys.txt

The encrypted file should contain at least:

  • •PROTON_EMAIL
  • •PROTON_BRIDGE_USER
  • •PROTON_BRIDGE_PASS (Bridge “Use this password”, not your Proton web password)
  • •SMTP_HOST, SMTP_PORT, SMTP_SECURITY

Quick start

  1. •Set up Proton Bridge (Linux) → see references/proton-bridge-setup.md.
  2. •Create a temporary plaintext env file (e.g., /tmp/proton.env), then encrypt it:
bash
bash scripts/encrypt_env.sh /tmp/proton.env <age-public-key>
  1. •Send a test email:
bash
python3 scripts/send_email.py \
  --to you@example.com \
  --subject "Test" \
  --body "Sent via Proton Bridge."

Notes / gotchas

  • •Bridge typically uses a local/self-signed cert for TLS on localhost. The sender script allows it.
  • •Bridge must be running for localhost SMTP to work.
  • •Do not commit or share secrets; only share the .age encrypted file if you intend to.
