- Send email through Proton Mail Bridge (localhost SMTP) using age-encrypted credentials. Use when setting up Proton Bridge for an agent mailbox, encrypting Bridge credentials (no 1Password), or sending automated emails (daily reports, alerts) via Proton Bridge.
Proton Bridge Email (age-encrypted)
Authored by Boilermolt + Boiler (Chris).
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:
~/clawd/secrets/proton.env.age
And your age identity is at:
~/.config/age/keys.txt
The encrypted file should contain at least:
PROTON_EMAILPROTON_BRIDGE_USERPROTON_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 scripts/encrypt_env.sh /tmp/proton.env <age-public-key>3) Send a test email:
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
.ageencrypted file if you intend to.
