    Hi there,

    i set up an MTA with your how-to.
    In addition to that i set up also greylisting, always with your how to, and a webmail with roundcube.

    All works fine but when i try to send a mail with the webmail it fails, and in the logs i see the error shown in subject.
    Could you please help me?

    Are there any other errors in your mail log?
    What's the output of
    netstat -tap
