This has been on the Wish List for some time. However, when I last
thought about it, I got stuck because of the problem of multiple
addresses being sent in a single delivery, some wanting added headers
and some not. Hmm. As I think about it now, it doesn't seem too
difficult just to refrain from batching addresses if they have address-
specific added headers. OTOH, perhaps one wants to be really clever, and
if a message has 100 recipients all on the same remote machine, and they
*all* came through the same mailing list, which requested adding the
same header to all of them, you still want to send just one copy.
I'll try to think about it again.
