Add to Email Header? X-Auto-Response-Suppress: All

Hi.  

We use Creatio to automatically send out emails to users based on certain triggers.  There is typically 50-100 a day -- We then get many "out of office" responses back, which are unnecessary. 

Is there a way to add to the email headers that Creatio generates?  If we could add "X-Auto-Response-Suppress: All" to the header, we would eliminate most if not all "out of office" responses.

Thanks
Rob
