IMAP Email Reader

Read, search, and manage email via IMAP protocol. Supports ProtonMail Bridge, Gmail IMAP, and any standard IMAP server.

Quick Start

Check for new emails:

node skills/imap-email/scripts/imap.js check

Fetch specific email:

node skills/imap-email/scripts/imap.js fetch <uid>

Mark as read:

node skills/imap-email/scripts/imap.js mark-read <uid>

Search mailbox:

node skills/imap-email/scripts/imap.js search --from "[email protected]" --unseen

Configuration

Quick setup (ProtonMail Bridge):

cd skills/imap-email
./setup.sh

The setup helper will prompt for Bridge credentials and test the connection.

Manual setup:

1. Copy .env.example to .env in the skill folder

2. Fill in your IMAP credentials

3. The .env file is automatically ignored by git

Environment variables:

IMAP_HOST=127.0.0.1          # Server hostname
IMAP_PORT=1143               # Server port
IMAP_USER=[email protected]
IMAP_PASS=your_password
IMAP_TLS=false               # Use TLS/SSL connection
IMAP_REJECT_UNAUTHORIZED=false  # Set to false for self-signed certs (optional)
IMAP_MAILBOX=INBOX           # Default mailbox

⚠️ Security: Never commit your .env file! It's already in .gitignore to prevent accidents.

ProtonMail Bridge setup:

• Install and run ProtonMail Bridge

• Use 127.0.0.1:1143 for IMAP

• Password is generated by Bridge (not your ProtonMail password)

• TLS: Use false (Bridge uses STARTTLS)

• REJECT_UNAUTHORIZED: Set to false (Bridge uses self-signed cert)

Gmail IMAP setup:

• Host: imap.gmail.com

• Port: 993

• TLS: true

• Enable "Less secure app access" or use App Password

• REJECT_UNAUTHORIZED: Omit or set to true (default)

Security Notes

• Store credentials in .env (add to .gitignore)

• ProtonMail Bridge password is NOT your account password

• Bridge must be running for ProtonMail IMAP access

• Consider using app-specific passwords for Gmail

Troubleshooting

Connection timeout:

• Verify IMAP server is running and accessible

• Check host/port configuration

• Test with: telnet <host> <port>

Authentication failed:

• Verify username (usually full email address)

• Check password is correct

• For ProtonMail Bridge: use Bridge-generated password, not account password

• For Gmail: use App Password if 2FA is enabled

TLS/SSL errors:

• Match IMAP_TLS setting to server requirements (true for SSL, false for STARTTLS)

• For self-signed certs (e.g., ProtonMail Bridge): set IMAP_REJECT_UNAUTHORIZED=false

• Check port matches TLS setting (993 for SSL, 143 for STARTTLS)

Empty results:

• Verify mailbox name (case-sensitive)

• Check search criteria

• List mailboxes with list-mailboxes
