Thanks a lot.

I have added a more affordable "Alternative, steps to reproduce" to
launchpad description.
I have also added 4 msdnmsgN(f+s).eml samples, where f=1=From failure
and s=2:Subject failure

Please note that msdnmsgN2.eml follows the proposed workaround but fails.

The workaround must add "speak English" in the Subject lines or not use
Qmail or even not use Return Receipts, because...

As I mentioned it before, no local "display name" configuration changes
the way the Return Receipt is sent for an incoming message (that was
written by somebody else) like mdnmsg2.eml and mdnmsg3.eml.

As I mentioned it before, no local "display name" configuration changes
the way the Return Receipt is sent when the error is in the Subject
line, like mdnmsg2.eml, mdnmsg3.eml and mdnmsg4.eml.

One cannot decently ask people who use accented letters or their own
alphabet like Cyrillic, Greek or Arabic to change their name and to stop
writing Subject lines in their own language because of a Thunderbird bug.

That's easy to understand
The best would be to remove the WORKARAUND and speed up a fix.
