The word "rechnung" is German for "invoice" according to Google.
It's reasonable for companies sending invoices in PDF format to
include the word "invoice" in the filenames. This makes it easier
for customers to find invoices when searching their local file
systems, and I know some end users who do exactly that instead of
organizing files into folders (they often don't utilize eMail folders
either, although I've had some success convincing people to change
their habits in this regard with positive results -- overall it's an
uphill battle, unfortunately).
So if a German company includes the word "rechnung" in the filenames
of their invoices, I don't really see why it should be a trigger, so
I guess I'm missing something here.
