Heh. that's what I get for not checking the RFC. *hangs head in shame*.

You're right tho, References lists every mail up the chain to the root of the
thread iirc, In-Reply-To is the one to add. Are they both Must-have's? or just
In-Reply-To?
One wonders how many email clients examine References over In-Reply-To and vice
versa, however, and what having differences between the two would do >:)
