+[Reroute Email](https://www.drupal.org/project/reroute_email) module uses
+`hook_mail_alter()` to prevent emails from being sent to users from
+non-production sites. It allows you to enter one or more email addresses that
+will receive the emails instead of delivering them to the original user.
+
+> This is useful in case where you do not want email sent from a Drupal site to
+> reach the users. For example, if you copy a live site to a test site for the
+> purpose of development, and you do not want any email sent to real users of
+> the original site. Or you want to check the emails sent for uniform
+> formatting, footers, ...etc.
+
+As we don't need the module configured on production (we don't need to reroute
+any emails there), it's best to do this in code using settings.local.php (if you
+have one) or the standard settings.php file.
+
+The first thing that we need to do is to enable rerouting. Without doing this,
+nothing will happen.
+
+```php
+$conf['reroute_email_enable'] = TRUE;
+```
+
+The next option is to whether to show rerouting description in mail body. I
+usually have this enabled. Set this to TRUE or FALSE depending on your
+preference.
+
+```php
+$conf['reroute_email_enable_message'] = TRUE;
+```
+
+The last setting is the email address to use. If you're entering a single
+address, you can add it as a simple string.
+
+```php
+$conf['reroute_email_address'] = 'person1@example.com';
+```
+
+In this example, all emails from the site will be rerouted to
+person1@example.com.
+
+If you want to add multiple addresses, these should be added in a
+semicolon-delimited list. Whilst you could add these also as a string, I prefer
+to use an array of addresses and the `implode()` function.
+
+```php
+$conf['reroute_email_address'] = implode(';', array(
+  'person1@example.com',
+  'person2@example.com',
+  'person3@example.com',
+));
+```
+
+In this example, person2@example.com and person3@example.com would receive their
+emails from the site as normal. Any emails to addresses not in the array would
+continue to be redirected to person1@example.com.
