@southtex - This information is referred to as the meta information on the customer that would help the agents track from where was the request raised that would in turn allow them to provide suggestions or steps towards resolution accordingly. 

That said, the same is also available only on tickets from specific sources, such as the help widget, feedback widget etc and not on email tickets. 

For now, we do not have an option with us to not capture this information, keeping in mind the privacy of the end-user. Let me have this passed along to our product security team and we’ll keep you updated on this same thread as soon as we have more information on this.

Thanks!
