DREDD: Let me judge your mails!

A tool to check on mailing lists health.

When you operate a mailing list server, you may want to time how long the messages take to reach the most common email providers. This enables you to detect any problem on a server, or with a specific provider. This simple tool should fulfill this requirement.

It is written in ruby, and requires basic ruby knowledge to install and customize it.

The code is pretty simple and should be easy to hack on. Contact me if you have any question.

How it works:

Create a specific mailing list (e.g. dredd@rezo.net) and an account for each mail provider you want to watch. Subscribe each of them to the dredd list. A background task must be set up, which will send mails to the mailing list. Another task will connect to each account and fetch the resulting messages. The result are displayed on a webapp. When emails are late, the system generates twitter messages on an account that the server admin will follow.

Installation

  • checkout the code
  • install the bundler gem
  • in the checkout directory run bundle install
  • (optional) change the database url in the config.ru file, by default a dredd.sqlite3 sqlite database will be used
  • in the checkout directory, run rackup
  • open your browser on http://localhost:9292
