So it's not your upstream writing that header?

This works in good weather, and fails in bad unfortunately.

The best is if your POP3 or IMAP service provider adds some reliable
header, be it Delivered-To:, X-Original-To:, X-Envelope-To: or
similar. If they don't, ask them if they can do that.

<http://home.pages.de/~mandree/mail/multidrop> sums up requirements for
multidrop in a way that is a tad less technical than a RFC.
