    Default Mail on new server

    My new dedicated was just set up tonight.. I am a busy beaver installing and setting up what I can..

    Just installed chkrootkit and set it to email the reports.. but they didnt go out.. the bounce notice shows:
    ... while talking to
    >>> MAIL From:<> SIZE=565
    <<< 550 5.1.8 invalid/host-not-in-DNS return address not allowed
    554 5.0.0 Service unavailable

    is that because the server is not fully set up yet??

    The problem is that the recieving mail server can't resolve the name of your mail server. Assuming that you are handling your own Domain Name Service, then yes, the problem is probably because you haven't set up DNS yet.
