IMAP Mail Skill

Send and receive email through your own IMAP/SMTP server.

A lightweight local REST API (FastAPI) runs as a bridge between the agent and your mail server — no third-party email platform needed.

Setup (first time)

1. Install dependencies

pip3 install fastapi uvicorn

2. Configure credentials

Create /etc/imap-mail.env (or any path, then set IMAP_MAIL_ENV):

MAIL_IMAP_HOST=mail.example.com
MAIL_IMAP_PORT=993
MAIL_SMTP_HOST=mail.example.com
MAIL_SMTP_PORT=465
[email protected]
MAIL_PASS=yourpassword
MAIL_FROM_NAME=MyAgent

3. Start the API server

# One-time / foreground
python3 {baseDir}/scripts/mail-api.py

# Or as a systemd service (recommended)
# See: {baseDir}/references/systemd.md

The API listens on http://127.0.0.1:8025 by default.

Checking Email

# List recent messages
python3 {baseDir}/scripts/check_inbox.py --inbox [email protected]

# Unread only
python3 {baseDir}/scripts/check_inbox.py --inbox [email protected] --unseen

# Specific folder
python3 {baseDir}/scripts/check_inbox.py --inbox [email protected] --folder Sent

# Read a specific message (use UID from list output)
python3 {baseDir}/scripts/check_inbox.py --inbox [email protected] --message 42

# Read message and save all its attachments
python3 {baseDir}/scripts/check_inbox.py --inbox [email protected] --message 42 --save-attachments /tmp/mail/

# List threads
python3 {baseDir}/scripts/check_inbox.py --inbox [email protected] --threads

# List all folders
python3 {baseDir}/scripts/check_inbox.py --inbox [email protected] --folders

Searching Email

# Search by keyword (subject + body)
python3 {baseDir}/scripts/search.py --inbox [email protected] --q "invoice"

# Search by sender
python3 {baseDir}/scripts/search.py --inbox [email protected] --from "[email protected]"

# Search by subject + date range
python3 {baseDir}/scripts/search.py --inbox [email protected] --subject "meeting" --since 2026-01-01

# Find unread messages
python3 {baseDir}/scripts/search.py --inbox [email protected] --unseen

# Find messages with attachments and save them
python3 {baseDir}/scripts/search.py --inbox [email protected] --has-attachments --save-attachments /tmp/mail/

# Find messages from VIP senders only
python3 {baseDir}/scripts/search.py --inbox [email protected] --vip

# Find only flagged/starred messages
python3 {baseDir}/scripts/search.py --inbox [email protected] --flagged

# Find flagged messages from a specific sender
python3 {baseDir}/scripts/search.py --inbox [email protected] --from "[email protected]" --flagged

# Combined filters: unread messages from a specific sender since a date
python3 {baseDir}/scripts/search.py --inbox [email protected] --from "[email protected]" --since 2026-03-01 --unseen

# Unread messages with a specific subject keyword
python3 {baseDir}/scripts/search.py --inbox [email protected] --subject "invoice" --unseen

# Search in a specific folder
python3 {baseDir}/scripts/search.py --inbox [email protected] --q "report" --folder Archive

Sorting Inbox (Personal vs Forwarded)

Automatically move messages into sub-folders based on addressing:

  • Personal — inbox address is directly in To: or Cc:
  • Forwarded — subject starts with Fwd: / FW:, or X-Forwarded-* / Resent-* headers present
  • Forwarded takes priority over Personal when both apply
# Preview what would be moved (no changes)
python3 {baseDir}/scripts/sort_inbox.py --inbox [email protected] --dry-run

# Sort all messages
python3 {baseDir}/scripts/sort_inbox.py --inbox [email protected]

# Sort only unread messages
python3 {baseDir}/scripts/sort_inbox.py --inbox [email protected] --unseen

# Custom folder names
python3 {baseDir}/scripts/sort_inbox.py --inbox [email protected] 
  --personal-folder MyInbox --forwarded-folder Forwards

# Sort a specific source folder
python3 {baseDir}/scripts/sort_inbox.py --inbox [email protected] --folder AllMail

Messages that match neither category (e.g. BCC, bulk mail) stay in the source folder.

Folder Management

# List all folders
python3 {baseDir}/scripts/manage_folders.py --inbox [email protected] --list

# Create a folder
python3 {baseDir}/scripts/manage_folders.py --inbox [email protected] --create Archive

# Delete a folder
python3 {baseDir}/scripts/manage_folders.py --inbox [email protected] --delete OldFolder

# Move a message to another folder (use UID from check_inbox output)
python3 {baseDir}/scripts/manage_folders.py --inbox [email protected] --move 42 --to Archive

# Move from a specific source folder
python3 {baseDir}/scripts/manage_folders.py --inbox [email protected] --move 5 --to INBOX --from-folder Junk

# Delete a message
python3 {baseDir}/scripts/manage_folders.py --inbox [email protected] --delete-msg 42

# Mark all messages in INBOX as read
python3 {baseDir}/scripts/manage_folders.py --inbox [email protected] --mark-seen

# Mark all messages in a specific folder as read
python3 {baseDir}/scripts/manage_folders.py --inbox [email protected] --mark-seen --from-folder Sent

# Mark one specific message as read (use UID from check_inbox output)
python3 {baseDir}/scripts/manage_folders.py --inbox [email protected] --mark-seen-uid 42

# Mark several specific messages as read (space-separated UIDs)
python3 {baseDir}/scripts/manage_folders.py --inbox [email protected] --mark-seen-uid 42 55 73

# Flag (star) specific messages as important
python3 {baseDir}/scripts/manage_folders.py --inbox [email protected] --flag-uid 42 55 73

# Flag ALL messages from a specific sender
python3 {baseDir}/scripts/manage_folders.py --inbox [email protected] --flag-from "[email protected]"
python3 {baseDir}/scripts/manage_folders.py --inbox [email protected] --flag-from "[email protected]"

# Remove flag from messages
python3 {baseDir}/scripts/manage_folders.py --inbox [email protected] --unflag-uid 42
python3 {baseDir}/scripts/manage_folders.py --inbox [email protected] --unflag-from "[email protected]"

Sending Email

# Send a plain text email
python3 {baseDir}/scripts/send_email.py 
  --to [email protected] 
  --subject "Hello" 
  --text "Message body here"

# Send to multiple recipients
python3 {baseDir}/scripts/send_email.py 
  --to [email protected] 
  --to [email protected] 
  --subject "Hello everyone" 
  --text "Hi all!"

# Reply to a message (preserves thread)
python3 {baseDir}/scripts/send_email.py 
  --to [email protected] 
  --subject "Re: Original Subject" 
  --text "My reply" 
  --reply-to "<original-message-id>"

Contact Memory (CRM)

Persistent notes and history per contact. Flagged senders are automatically tracked — when their message arrives, the agent pulls full context and reports in detail.

# Look up everything about a contact
python3 {baseDir}/scripts/manage_contacts.py --get [email protected]

# List all contacts
python3 {baseDir}/scripts/manage_contacts.py --list

# Save a contact with name and tags
python3 {baseDir}/scripts/manage_contacts.py --save [email protected] --name "Craig Smith" --tags "client,priority"

# Append a timestamped note (agent does this automatically after each flagged message)
python3 {baseDir}/scripts/manage_contacts.py --note [email protected] "Wants proposal by Friday. Budget ~$5k."

# Delete a contact
python3 {baseDir}/scripts/manage_contacts.py --delete [email protected]

How it works with flagged mail: 1. Flagged (starred) UNSEEN messages are processed separately from regular mail 2. For each flagged message, the agent fetches the sender's full contact history 3. Reports to user with: who wrote, what they want, full context from previous interactions 4. Automatically saves a note summarizing the new message

Auto-Rules (persistent flag/action on incoming mail)

Rules are defined once and applied automatically to every new (UNSEEN) message on each mail check — until you remove them.

# Flag ALL future messages from Craig as important (persists forever)
python3 {baseDir}/scripts/manage_rules.py --inbox [email protected] --add --from "[email protected]"

# Flag messages with "URGENT" in subject
python3 {baseDir}/scripts/manage_rules.py --inbox [email protected] --add --subject "URGENT"

# Auto-mark-as-read messages from a newsletter
python3 {baseDir}/scripts/manage_rules.py --inbox [email protected] --add --from "[email protected]" --action mark-seen

# List all active rules
python3 {baseDir}/scripts/manage_rules.py --inbox [email protected] --list

# Apply all rules right now (without waiting for next cron)
python3 {baseDir}/scripts/manage_rules.py --inbox [email protected] --apply

# Temporarily disable a rule (ID from --list)
python3 {baseDir}/scripts/manage_rules.py --inbox [email protected] --disable 1

# Re-enable
python3 {baseDir}/scripts/manage_rules.py --inbox [email protected] --enable 1

# Remove permanently
python3 {baseDir}/scripts/manage_rules.py --inbox [email protected] --remove 1

Scheduled Send

Queue emails for future delivery. The API background scheduler checks every 60 seconds.

# Schedule via API directly (ISO datetime, UTC recommended)
# POST /inboxes/{inbox}/scheduled
# Body: {"to": ["[email protected]"], "subject": "...", "text": "...", "send_at": "2026-03-10T09:00:00Z"}

# List all scheduled messages
# GET /inboxes/{inbox}/scheduled

# Cancel a scheduled message
# DELETE /inboxes/{inbox}/scheduled/{id}

IMAP IDLE (Push Notifications)

Instead of polling every N minutes, IDLE keeps a persistent connection open so the server pushes notifications immediately when new mail arrives.

Add to your env file:

# Required: webhook URL to POST new mail events to
MAIL_IDLE_WEBHOOK=http://127.0.0.1:8080/mail-event

# Optional: folder to watch (default: INBOX)
MAIL_IDLE_FOLDER=INBOX

When new mail arrives, the API POSTs to the webhook:

{
  "event": "new_mail",
  "uid": "123",
  "subject": "Hello",
  "from_": [{"name": "Alice", "email": "[email protected]"}],
  "vip": false,
  ...full message fields...
}

Check IDLE status:

# GET http://127.0.0.1:8025/idle/status

VIP Sender List

Mark specific senders as VIP — their messages will have "vip": true in the API response and in IDLE webhook payloads, enabling urgent/priority handling.

Add to your env file:

[email protected],[email protected]

Messages from VIP senders are flagged in all responses ("vip": true) and can be filtered:

# Show only VIP messages
python3 {baseDir}/scripts/search.py --inbox [email protected] --vip

API Endpoints

The local REST API at http://127.0.0.1:8025 exposes:

Environment Variables

Variable Default Description
MAIL_IMAP_HOST — IMAP server hostname
MAIL_IMAP_PORT 993 IMAP port (TLS)
MAIL_SMTP_HOST — SMTP server hostname
MAIL_SMTP_PORT 465 SMTP port (TLS)
MAIL_USER — Email login / address
MAIL_PASS — Password
MAIL_FROM_NAME Agent Display name in From header
MAIL_IDLE_WEBHOOK — Webhook URL for IMAP IDLE push events
MAIL_IDLE_FOLDER INBOX Folder to watch with IDLE
MAIL_VIP_SENDERS — Comma-separated VIP email addresses
MAIL_SCHEDULED_DB /tmp/imap-mail-scheduled.db SQLite path for scheduled sends
MAIL_ALLOW_SELF_SIGNED false Set true to skip TLS cert verification (self-signed certs)
IMAP_MAIL_API http://127.0.0.1:8025 API base URL (for scripts)
IMAP_MAIL_ENV /etc/imap-mail.env Path to env file
IMAP_MAIL_PORT 8025 API listen port

Security Notes

  • Credentials — mail login and password are stored in a local env file (e.g. /etc/imap-mail.env), readable only by the service user. Never hardcode credentials in scripts.
  • SSL/TLS — all IMAP and SMTP connections use TLS by default. Certificate verification is enabled by default (ssl.create_default_context()). Set MAIL_ALLOW_SELF_SIGNED=true only if your mail server uses a self-signed certificate and you accept the risk.
  • Local API only — the REST bridge listens on 127.0.0.1 (loopback) only and is not exposed to the network.
  • Webhook (IDLE) — if MAIL_IDLE_WEBHOOK is set, full message contents (including body) are POSTed to that URL on new mail. Ensure the webhook URL is a trusted local endpoint.

Compatibility

Works with any standard IMAP/SMTP server: - Self-hosted: Dovecot, Postfix, Exim, Maddy - Hosted: Gmail (App Password), Outlook/Hotmail, Yahoo Mail, Fastmail, ProtonMail Bridge, and any provider that supports IMAP

Note: Self-signed TLS certificates are accepted automatically.
