+Email configuration
+===================
+
+User settings
+-------------
+
+To receive email notifications, users of Kanboard must have:
+
+- Activated notifications in the settings page
+- Have a valid email address in their profile
+
+Server settings
+---------------
+
+By default, Kanboard will use the bundled PHP mail function to send emails.
+Usually that require no configuration if your server can already send emails.
+
+However, it's possible to use other methods, the SMTP protocol and Sendmail.
+
+### SMTP configuration
+
+Create a blank `config.php` file or use the template `config.default.php` and set those values:
+
+```php
+// We choose "smtp" as mail transport
+define('MAIL_TRANSPORT', 'smtp');
+
+// We define our server settings
+define('MAIL_SMTP_HOSTNAME', 'mail.example.com');
+define('MAIL_SMTP_PORT', 25);
+
+// Credentials for authentication on the SMTP server (not mandatory)
+define('MAIL_SMTP_USERNAME', 'username');
+define('MAIL_SMTP_PASSWORD', 'super password');
+```
+
+### Sendmail configuration
+
+By default the sendmail command will be `/usr/sbin/sendmail -bs` but you can customize that in your config file.
+
+Example:
+
+```php
+// We choose "sendmail" as mail transport
+define('MAIL_TRANSPORT', 'sendmail');
+
+// If you need to change the sendmail command, replace the value
+define('MAIL_SENDMAIL_COMMAND', '/usr/sbin/sendmail -bs');
+```
+
+### The sender email address
+
+By default, emails will use the sender address `notifications@kanboard.net`.
+It's not possible to reply to this address.
+
+You can customize this address by changing the value of the constant `MAIL_FROM` in your config file.
+
+```php
+define('MAIL_FROM', 'notifications@kanboard.net');
+```
+
+That can be useful if your SMTP server configuration doesn't accept the default address.
+
+
+### Check for due tasks
+
+Every day, Kanboard can check for due tasks, to do that you have to setup a cronjob on your server and use the Kanboard command line interface.
+
+Here a example:
+
+```bash
+# Everyday at 8am we check for due tasks
+0 8 * * *  cd /path/to/kanboard && ./kanboard send-notifications-due-tasks >/dev/null 2>&1
+```

docs/reverse-proxy-authentication.markdown

@@ -13,8 +13,8 @@ How does this work?
   - If it is the same web server that runs Kanboard, the CGI spec specifies this header to be REMOTE_USER (see [RFC 3875](http://www.ietf.org/rfc/rfc3875) §4.1.11). For example, Apache adds REMOTE_USER by default if `Require valid-user` is set. Note this header is only set for CGI (like PHP), and not if Apache is a reverse proxy to another Apache running Kanboard. It works the same with IIS and nginx according to their documentation.
   - If it is a real reverse proxy, the HTTP ICAP extension draft spec proposes the header to be X-Authenticated-User (see [IETF draft spec §3.4](http://tools.ietf.org/html/draft-stecher-icap-subid-00#section-3.4)). This de-facto standart has been adopted by a number of tools.
 - Kanboard retrieves the value of the specified HTTP header, and:
-  - if the user does not exist yet, creates it (it also checks if it is the default admin).
-  - authenticates the given user without any prompt, assuming it is valid (so it does NOT prompt the login page).

 This is not in the scope of this documentation. You should check that the user login is sent by the reverse proxy using a HTTP header, and find which one.
