What about spam with a faked FROM address which seems to be from a local 
user?  I think the point is that this strategy can cause a copy of the 
spam to end up being added as a sent item.  The extra header field was 
being added presumably to identify real sent mail from faked spam and 
hence only add real sent messages to the sent folder?
