    You seem to use a self-signed SSL certificate. To get rid of the error, you need a officially signed ssl cert. You can get ne from Let's encrypt for free like this:

    Then configure Postfix to use it:

    cd /etc/postfix
    mv smtpd.cert smtpd.cert_bak
    mv smtpd.key smtpd.key_bak
    ln -s /usr/local/ispconfig/interface/ssl/ispserver.crt smtpd.cert
    ln -s /usr/local/ispconfig/interface/ssl/ispserver.key smtpd.key
