<h3>Mail user API (advanced)</h3>

<p>Use your box&rsquo;s mail user API to add/change/remove users from the command-line or custom services you build.</p>

<p>Usage:</p>

<pre>curl -X <b>VERB</b> [-d "<b>parameters</b>"] --user {email}:{password} https://{{hostname}}/admin/mail/users[<b>action</b>]</pre>

<p>Brackets denote an optional argument. Please note that the POST body <code>parameters</code> must be URL-encoded.</p>

<p>The email and password given to the <code>--user</code> option must be an administrative user on this system.</p>

<h4 style="margin-bottom: 0">Verbs</h4>

<table class="table" style="margin-top: .5em">
<thead><th>Verb</th> <th>Action</th><th></th></thead>
<tr><td>GET</td><td><i>(none)</i></td> <td>Returns a list of existing mail users. Adding <code>?format=json</code> to the URL will give JSON-encoded results.</td></tr>
<tr><td>POST</td><td>/add</td> <td>Adds a new mail user. Required POST-body parameters are <code>email</code> and <code>password</code>.</td></tr>
<tr><td>POST</td><td>/remove</td> <td>Removes a mail user. Required POST-by parameter is <code>email</code>.</td></tr>
<tr><td>POST</td><td>/privileges/add</td> <td>Used to make a mail user an admin. Required POST-body parameters are <code>email</code> and <code>privilege=admin</code>.</td></tr>
<tr><td>POST</td><td>/privileges/remove</td> <td>Used to remove the admin privilege from a mail user. Required POST-body parameter is <code>email</code>.</td></tr>
</table>

<h4>Examples:</h4>

<p>Try these examples. For simplicity the examples omit the <code>--user me@mydomain.com:yourpassword</code> command line argument which you must fill in with your administrative email address and password.</p>

<pre># Gives a JSON-encoded list of all mail users
curl -X GET https://{{hostname}}/admin/mail/users?format=json

# Adds a new email user
curl -X POST -d "email=new_user@mydomail.com" -d "password=s3curE_pa5Sw0rD" https://{{hostname}}/admin/mail/users/add

# Removes a email user
curl -X POST -d "email=new_user@mydomail.com" https://{{hostname}}/admin/mail/users/remove

# Adds admin privilege to an email user
