NDR Language in Exchange 2007

I have some troubles with NDR's in Exchange 2007 sp1.
What is it that sets the language?

My production environment:
2 CA+HT servers
3-node scc-cluster with 2 MBX-servers.
All is Exchange 2007 sp1 installed on windows server 2003 SP2.

My test environment
1 single Exchange 2007 ca+ht+mbx. Installed on windows 2003 R2.

I've set the following attributes (which i thought would solve my problem) in all HT-servers
ExternalDsnDefaultLanguage              : en-US
ExternalDsnLanguageDetectionEnabled     : False
InternalDsnDefaultLanguage              : en-US
InternalDsnLanguageDetectionEnabled     : False

It started with a german customer to us that resolved a NDR in swedish (everything resides in sweden, regional settings are set to swedish on all servers).

Then I started making some tests and here are the results.
n-e-a means non-existing address.
n-e-d means non-existing domain.
production.com is my external production domain. test.lan is of course my testenvironment.
Mails are routed between test and production with dedicated send connectors.

If I send emails from my production-exchange to n-e-a@production.com I get an NDR in English
If I send emails from my production-exchange to n-e-a@n-e-d.com I get a swedish NDR (could be my spamfilter)
If I send emails from my production-exchange to n-e-a@test.lan i get a swedish NDR (does not pass spamfilter)

If I send emails from my test-exchange to n-e-a@test.lan I get a NDR in English.
If I send emails from my test-exchange to n-e-a@n-e-d.com I get a NDR in English. (I have to manually remove this from exchange que with 'remove with ndr' since i got no internet send connector in my test-exchange)
If I send emails from my test-exchange to n-e-a@production.com I get a NDR in swedish.

If I send an email from my other company (I'm a consultant) to n-e-a@production.com I get a NDR in swedish.
If I send an email from my g-mail to n-e-a@production.com I get a NDR in English.

Why does NDR in swedish exists?
How can I manually set this to always be in English?

I'm stuck and all help is appreciated.

I've read those articles and they refere to the setting InternalDsnDefaultLanguage.
And as I described earlier this setting is already set.

Just to test I've created a postmaster mailbox in my testenvironment and set the language to english.
No luck...  still in swedish. I've attached a header sent from my production to my test environment to a nonexistingaddress and I get a NDR in swedish.
