Actually, I'm pretty sure it is only the Received header that would ever show more than once in the main header of a message. [Content-type and related part-specific lines might show up more than once, but only once per part.] That would take some special handling. I think the factor to put to use for Received headers specifically is that their ordering is consistent. So each Received line encountered should be pushed into an array, perhaps. Then the lines could be popped to retrace the route from origin to destination. So it is not quite that simple. Still, it is not inordinately complicated either. Good design, with small, well-designed subroutines, should make it fairly straightforward.
