    Seems as if the ssl configuration of postfix is broken. Did you change anything in the postfix ssl cert config or postfix config files or did you rename or remove ssl certificate files before the issue started?

    Please try to answer my question from above:

    Did you change anything in the postfix ssl cert config or postfix config files or did you rename or remove ssl certificate files before the issue started?

    and the ssl certs had been removed from postfix main.cf:

    smtpd_tls_CAfile =
    smtpd_tls_CApath =
    smtpd_tls_cert_file =
    smtpd_tls_key_file =
