Supply IP address in outgoing mails

With this plugin installed and enabled, all email messages sent from WebMail will have X-Originating-IP header with sender's IP address there. Naturally, it's about actual IP of user, not the WebMail installation IP.

Upon downloading and extracting plugin package, rename its main directory from:

plugin-x-originating-ip-master

to:

x-originating-ip

Then you'll need to deploy the plugin so that its index file is available at the following location:

data/plugins/x-originating-ip/index.php

To enable the plugin, add the following to array defined in data/settings/config.php file:

'plugins.x-originating-ip' => true,
