====== Email ======

Email Services for 42d.io and Wiki42d are setup to use Postfix. The email address in use is "dat@42d.io"

In the current setup dat@42d.io email box exists only on Google Workspaces.

===== Wiki42d =====

For Wiki42d, password email resetting is now supported.

A Captcha plugin is installed which will require the user to answer a math question after 3 failed attempts.
