Exchange 2010 Sp3 Rollup 4 - 5.6.0 invalid content

[substyle 20]

Hallo zusammen,

 

folgendes Probelm.

Mail an Exchange 2010 SP3 R4 wird über Postfix an Exchange 2010 per SMTP gesendet.

Client der die Mail an Postfix gibt ist ein Thunderbird 24.3.0.

 

Der Exchange wird immer ein NDA raus.

 

5.6.0 Invalid Content

 

Sogar wenn die Mail und die Betreff der Mail leer ist, und die Mail auch keinen Anhang hat.

 

Anbei der Header. Weis da jemand Rat?

LG subby
