    The output you posted shows that your mail system works fine on sending and receiving side. Even the open relay test, which is this part:

    Code:
    RCPT TO:<[email protected]>
    450 4.1.2 <[email protected]>: Recipient address rejected: Domain not found
    is as to be expected. The result must be domain not found on a working system. SMTP and IMAP authentication works fine as well according to the output.

    It would be helpful if you describe what your issue is as you do not have any problem with your mail setup according to the test results.

    Hi thanks for your quick answer.
    i use mailspring and when i setup the account i get the following error:
    The SMTP server would not relay a message. You may need to authenticate. (SMTP)
    from there one i can not setup the account.

    You must enable SMTP authentication in mailspring, the username is the complete email address and the password is the password of your mail account. Sending email through a mail server without authentication is not permitted, as your server would be misused for sending spam then.
