    What is the problem with the configuration?
    I have other server with de same relay ISP, but with postfix manual installation and this work fine.

    The receiving server doesn't like the sender domain address (does it actually exist, can it be resolved and does it have valid DNS A & MX records?), you can also take a look at some of these threads for ideas about what might be wrong.
