This simple plugin that adds a “Host-Header” HTTP header where you can define your webhost. Web partners that scan for compromised websites can notify hosts more effectively to cleanup sites.
This plugin is super overkill. Adding a simple file with the following to your <code>mu-plugins.php</code> will have the same effect.
<pre><code>// custom-host-header.php
add_filter( 'wp_headers', function( $headers ) {
 $headers['Host-Header'] = 'YOUR HOST NAME HERE';
 return $headers;
} );
</code></pre>

WordPress Host Headers

Add a Host-Header to track down hosting partners in helping combat web spam.
