Exchange 5.5 recipient get the X-header. The Exchange 2003 recipient
doesn't. Not all the SMTP headers are stripped. Just the X-headers are
stripped.

If you create make it so that in Exchange 5.5, a copy of a message
sent to an Ex55 recipient is sent to an Ex2003 recipient, does the 5.5
recipient get the X-header and the 2003 not? Also, is all of the SMTP
header stripped, or just the X-header?
