RFC822 is unambiguous about this. Section 6.2.2 EXPLICITLY states

	When a message crosses a domain boundary, all
	addresses must be specified in the full format,
	ending with the top-level name-domain in the
	rightmost field.

You crossed a domain boundary when you forwarded the mail to
your backbone site. It was YOUR responsibility to fully qualify those
addresses, not someone elses. The backbone is attempting to
qualify a garbage address. You can't blame it for making garbage
out of garbage.

Why is it more logical to expect EVERYONE to know your local mail
forwarding rules so that they can reply to your mail and
correctly send mail to the CC lines? It seems that fully
qualified addresses are easiest for everyone.
