Okay how to solve this?
Here the logs attached.
It looks like that postfix don't know to handle other users.
If I send from allowed domains which I entered in the protected_destinations it
works.
If I send a mail from gmail:
Feb 13 21:44:06 CGSG postfix/smtpd[8296]: Anonymous TLS connection established

Any ideas?

Fix the "server configuration error" detailed in your logs.
