I got a little question!!
I regionized that i got a lot of "Automatic Reply" Messages around the Christmas days! Some mails got me my original Message in the reply message! Okay it just says "merry Christmas" as text and ":-)" as subject nothing else.
It was send from a phantasy name, and phantasy mailbox name but with my original Domainname...!
Now i checked my Postfix configuration on the server and saw this information:
