wafflesbot: Email auto reply bot for JMAP mailboxes

wafflesbot sends form replies to unreplied emails in a JMAP mailbox (such as Fastmail).

wafflesbot excels at automatically asking tech recruiters for compensation information.

Built on:

• JMAP client: jmapc
• Quoted email reply assembly: replyowl

Installation and usage with Docker

A Docker container is provided which runs wafflesbot to reply to emails via JMAP server events. JMAP API authentication and reply details should be configured using environment variables.

Example docker-compose.yaml:

version: "3.7"

secrets:
  jmap_api_token:
    file: path/to/file/with/your/jmap_api_token

services:
  waffles:
    image: ghcr.io/smkent/waffles:latest
    environment:
      JMAP_HOST: jmap.example.com
      JMAP_API_TOKEN: /run/secrets/jmap_api_token
      WAFFLES_MAILBOX: folder-or-label-name
      WAFFLES_REPLY_FILE: /autoreply.html
      # WAFFLES_DRY_RUN: "true" # Uncomment to log actions but not send email
      # WAFFLES_DEBUG: "true"   # Uncomment to increase log verbosity
      # Set TZ to your time zone. Often same as the contents of /etc/timezone.
      TZ: PST8PDT
    restart: unless-stopped
    volumes:
      - path/to/your/reply/content.html:/autoreply.html:ro
    secrets:
      - jmap_api_token

Start the container by running:

docker-compose up -d

Debugging information can be viewed in the container log:

docker-compose logs -f

Installation from PyPI

wafflesbot is available on PyPI:

pip install wafflesbot

Usage

wafflesbot provides the waffles command, which can either:

1. Run as a service and reply to emails received via JMAP server events (the default)
2. Run as a script to examine recent emails (such as interactively or via a cronjob)

Environment variables:

• JMAP_HOST: JMAP server hostname
• JMAP_API_TOKEN: JMAP account API token

Required arguments:

• -m/--mailbox: Name of the folder to process
• -r/--reply-content: Path to file with an HTML reply message

Optional arguments:

• -l/--limit: Maximum number of emails replies to send (only valid with -s/--script)
• -n/--days: Only process email received this many days ago or newer (only valid with -s/--script)
• -p/--pretend: Print messages to standard output instead of sending email
• -s/--script: Set to run as a script instead of an event-driven service
