    Hi guys,

    i set up a new email account on my server with ispconfig 3 and ubuntu 18.04.
    I get the following message during setup the email with ispconfig:

    A mail account ..... cannot connect, because an SSL/ TSL certificate for is not rusted. 
    reason: the signing certificate authority is not known. 
    how can i fix this problem?
    thanks for your kind help
