zonemta-limiter

Limiter plugin for ZoneMTA. Install this to avoid accidental messagebombs where the same sender is sending excessive mail to the same recipient.

Setup

Add this as a dependency for your ZoneMTA app

npm install zonemta-limiter --save

Add a configuration entry in the "plugins" section of your ZoneMTA app

...
  "plugins": {
    "modules/zonemta-limiter": {
        "enabled": "sender",
        "prefix": "zl:",
        "limit": 100,
        "windowSize": 1800,
        "debug": false
