sys-ctl-hlth-msmtp

Description

This Ansible role sends periodic health check emails using msmtp to verify that your mail transport agent is operational. It deploys a simple script and hooks it into a systemd service and timer, with failure notifications sent via Telegram.

Overview

Optimized for Archlinux, this role creates the required directory structure, installs and configures the sys-ctl-hlth-check script, and integrates with the sys-ctl-alm-telegram role. It uses the sys-timer role to schedule regular checks based on your customizable OnCalendar setting.

Purpose

The sys-ctl-hlth-msmtp role ensures that your mail transport system stays available by sending a test email at defined intervals. If the email fails, a Telegram alert is triggered, allowing you to detect and address issues before they impact users.

Features

• Directory & Script Deployment: Sets up sys-ctl-hlth-msmtp/ and deploys a templated Bash script to send test emails via msmtp.

• Systemd Service & Timer: Provides .service and .timer units to run the check and schedule it automatically.

• Failure Notifications: Leverages sys-ctl-alm-telegram to push alerts when the script exits with an error.

• Configurable Schedule: Define your desired check frequency using the on_calendar_health_msmtp variable.

• Email Destination: Specify the recipient via the users.administrator.email variable.
