Sorry, that one doesn't mean a thing to me.  Do the message headers in the
bounce give a clue what mail program was used?

"Other or undefined network or routing status" is a 440 or 540 return
status, and since she gets the message, presumably 440 (transient, rather
than permanent), but you'd probably need to know what software they're
using at the other end to have a real clue what it is.

If there's anything in the message or headers that tells you it is actually
a transient error, I'd tend to write a filter to delete it unseen and
forget about it.
