<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>

<li>Enable or disable SMTP with a single toggle</li>
<li>Supports SSL, TLS, or no encryption</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>
