Email Forwarder

This script forwards new emails from a source IMAP account (e.g., GMX) to a destination IMAP account (e.g., MXRoute), avoiding duplicates by tracking Message-IDs.

Setup

Run the install script: ./install.sh

This will set up the virtual environment, systemd services, and provide post-install instructions.

Configuration (.env)

SOURCE_HOST: Source IMAP server (e.g., imap.gmx.com)
SOURCE_PORT: Port (default 993)
SOURCE_USER: Source email/username
SOURCE_PASS: Source password
DEST_HOST: Destination IMAP server (e.g., yourserver.mxrouting.net)
DEST_PORT: Port (default 993)
DEST_USER: Destination email/username
DEST_PASS: Destination password
FOLDERS: Folders to sync (default "INBOX"; use "all" for all folders or comma-separated list like "INBOX,Sent")
DRY_RUN: Set to true for testing without forwarding (default false)
UPTIME_SUCCESS_URL: URL for success ping
UPTIME_FAIL_URL: URL for failure ping

How It Works

Uses time-based search (SINCE) with last_run.txt to find emails since last run.
Extracts Message-ID, checks against local file and destination IMAP for duplicates.
Forwards via IMAP APPEND; updates last_run.txt on success.
Logs activity; systemd handles Uptime Kuma pings.

Monitoring with Uptime Kuma

Success: Pings ${UPTIME_SUCCESS_URL} after forwarding.
Failure: OnFailure pings ${UPTIME_FAIL_URL}.

Troubleshooting

Logs: journalctl --user -u email_forwarder.service
Test: source venv/bin/activate && python main.py
Timezone issues: Adjust UTC offset in script if needed.
