    Hello all,

    Im using the latest stable ispconfig 3.1 on ubuntu server 16.04.
    It seems there is an issue with using postfix with mail relay without authentication. Its configured via gui,
    the relay host im using is
    On my other mailservers Im having not such a problem.
    The relay works definitive without auth!

    Can someone help?

    Ahoi all,

    as workaround: remove the relay in gui and set it by hand in That works.
    Something in ispconfig sends "All-whitespace username" and it should not.

    Hope, its corrected in next patch?
