    On an ispconfig 3.1.13 with letsencrypt configured certificates the MTA complains about certificate authentification belongs to another domain.
    The server addresses for connection is and the certificate offered by the postfix server is general certificate that was generated at first install.
    How should I generate a specific certificate for and each other mail.domain.tld managed on this mail server without having to accept security exception by the MTA ?
