<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>

<p>CodingBunny Mail SMTP allows you to easily configure an SMTP server to send all outgoing emails from your WordPress website.</p>
<p>By default, WordPress uses the <code>wp_mail()</code> function which relies on the server’s PHP mail configuration. This often leads to delivery issues or emails ending up in spam. This plugin solves that problem by routing emails through a reliable SMTP server.</p>
<h3>Key Features</h3>
<ul>
<li>Enable or disable SMTP with a single toggle</li>
<li>Supports SSL, TLS, or no encryption</li>
<li>Optional SMTP authentication (username & password)</li>
<li>Secure password storage using encryption</li>
<li>Custom “From Email” and “From Name”</li>
<li>Built-in test email tool</li>
<li>Lightweight, no third-party dependencies</li>
<li>Fully compatible with WordPress PHPMailer</li>
<li>Clean and accessible admin interface</li>
</ul>
<h3>Security</h3>
<p>The SMTP password is encrypted before being stored in the database** and is never displayed in plain text in the WordPress admin area.</p>
<h3>Configuration</h3>
<p>You can configure the following options:</p>
<ul>
<li>SMTP Host (e.g. <code>smtp.example.com</code>)</li>
<li>SMTP Port (e.g. <code>587</code>)</li>
<li>Encryption: None, TLS, or SSL</li>
<li>Enable/Disable SMTP authentication</li>
<li>SMTP Username & Password</li>
<li>Sender Email Address</li>
<li>Sender Name</li>
</ul>
<p>After saving, use the Test Email section to verify your configuration.</p>
<h3>Uninstall</h3>
<p>When the plugin is uninstalled, all plugin options (including encrypted credentials) are removed from the database.</p>
