These emails are entirely generated by the device. Horde simply parses  
it into a structure that Horde_Mail can send and pushes it on it's  
way. I've tested this locally here, from my iPad and it works as  
expected.

What email address is the iPhone's ActiveSync account configured with?  
If you provide a wiretrace of the communication between the device and  
the Horde server during the ActiveSync transaction we can be sure if  
it's coming from the device, or if it's something Horde does during  
processing the request.
