<p>The <a href="https://kibb.in/ssmtp" rel="nofollow ugc">Simple SMTP Mailer</a> plugin allows you to easily configure WordPress to use SMTP instead of the PHP mail function.</p>
<p><strong>This should only really be used in a development environment.</strong></p>
<h3>Simple SMTP Mailer Settings</h3>
<ul>
<li><strong>Host</strong>: The mail server (Defaults to smtp.gmail.com)</li>
<li><strong>Username</strong>: The username used for connecting to the SMTP server</li>
<li><strong>Password</strong>: The password used for connecting to the SMTP server</li>
<li><strong>Port</strong>: The port to use when sending an email (587, 465 or 25. Defaults to 587)</li>
<li><strong>Security</strong>: The type of encryption security to use when sending an email (TLS or SSL. Defaults to TLS)</li>
<li><strong>Debug</strong>: Enable debugging</li>
</ul>
<p>All settings can be overridden by assigning array values to the SSMTP_MAILER constant in wp-config.php. This is useful for automating local deployment.</p>
<pre><code>define(
    'SSMTP_MAILER',
    array(
        'host' => emailhost.com,
        'username' => username,
        'password' => password,
        'port' => 25,
        'security' => 'SSL'
    )
);
</code></pre>
