    For example i tried to use
    telnet 25
    or port 465, 587

    but in terminal i can still see just
    root@host:~# telnet 25
    Connected to
    Escape character is '^]'.
    220 ESMTP Postfix (Debian/GNU)
    and nothing else

    My signature has link to e-mail setup tutorial.
    ISPConfig install should have created the certificate and set up e-mail server, ftp, etc. to use it. So maybe certificates are in order? Use Internet Search engines with
    ssl testing mail server

    That's fine so far. As @Taleman suggested, search on the internet on how to do such a test properly. You just connected to the system, so the result is fine, and it waits now for further input, and hos that is done and which commands must be issued can be found in various guides on the net.
