    Then I have no idea....

    As mxtoolbox couldn't connect... are you sure you route port 25 to your postfix server? You said it's in DMZ but check again if port 25 is pointed elsewhere...

    i will check this.

    When i look in Ispconfig Monitor/Mail-error-log i see this
    Dec 30 13:39:09 server amavis[2228]: (02228-02) (!!)TROUBLE in process_request: Error writing an SMTP response to the socket: Broken pipe at (eval 97) line 1346

    Is this maybe the problem?

    It seems that DNS is not properly configured
    Code:
    [[email protected] ~]$ telnet 87.209.2.17 25
    Trying 87.209.2.17...
    Connected to 87.209.2.17.
    Escape character is '^]'.
    220 server1.kutscher.nl ESMTP Postfix (Ubuntu)
    quit
    221 2.0.0 Bye
    Connection closed by foreign host.
    
    Ok, the port 25 is open and a server1 (your server?) is receptive
    Code:
    [[email protected] ~]$ host -tmx kutscher.nl
    kutscher.nl mail is handled by 10 mail.kutscher.nl.
    [[email protected] ~]$ host -ta mail.kutscher.nl
    mail.kutscher.nl has address 87.209.2.17
    
    Ok, the MX record is property configured ... but point to a host called "mail", this could be a problem...
    Code:
    [[email protected] ~]$ host 87.209.2.17
    17.2.209.87.in-addr.arpa domain name pointer ip17-2-209-87.adsl2.static.versatel.nl.
    [[email protected] ~]$ host -ttxt kutscher.nl
    kutscher.nl has no TXT record
    
    Not Ok, the PTR record not point to your server and there is not a SPF txt record

    Try send a message to your server and post the log.
    Hope this help

    You have a typo in /etc/postfix/master.cf, as 'submission' is not an argument to a command, but should be the beginning of a new line itself.
