There is also no direct support for this in accordance with the documentation.
BUT
if your http://mydomain.com/ is hosted on Google apps and you create the user hello@mydomain.com as a gmail account and configure the email forwarding rule on it to hello@emailprocessor.appspotmail.com it should work, since it works for any general email sending email. It saves the original headers such as sender, etc.
I am pretty sure that most other mail services or servers can support this feature. check the documentation of your postal service.
Pay ATTENTION! this should be emailprocessor.appspotmail.com note appspotmail.com not appspot.com
I have not tried myself yet, so I will be happy if you confirm that this works. Again, it is necessary.
