Pise to, ze tam mate pro TLS neco self-generated.... a navic to umoznuje i SSL, proc jste nezkusil i tento certifikat pouzit pro postovni server a jeho TLS ?
The certificate is not valid for the server's hostname.
The certificate is self-signed.
There are one or more fatal problems which causes the certificate not to be trusted.
