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

Quick start

Set up Proton Bridge (Linux) → see
```
references/proton-bridge-setup.md
```
.
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>

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
```
.age
```
encrypted file if you intend to.
