I doubt they even parse the headers.  To retain them they'd have to parse
them and process in real-time.  I am reasonably certain that doesn't happen.

Actually, a "TAG" field in their template (guaranteed to be returned
unmolested), and a "Response" field (containing a restricted set of reply
codes) would do the job.

What I'd do is put the domain in the subject line, and then parse that on the
return.  That gives you the tuple you need  (domain, tracking number) which
then can be matched against subsequent messages concerning the same domain.

Unfortunately, there's no guarantee that the format of responses won't
change out from under you.

This is one of the problems with "human-readable" as opposed to
machine-defined systems.
