actually, Qmail (as MTA) does not touch the email header; except for including a Received: header.
Thus, this is a problem of the sending client.

Since you >>forward<< this message while receiving it, you can check and perhaps manipulate the header in the .qmail file.
Have a look at the mess822 from DJB.

This does not look like a Qmail problem, thus other MTAs probably would suffer from the same fate.
