    Do not use the same password?

    re-reading your message, I do not think that you can.
    all domains on your server point to the same IP.
    So telneting to domain xxxx, will be the same IP as telneting to domain yyyy.

    Owner of domain xxxx can still telnet to yyyy, but he will need to use the username and password of domain xxxx to login.
    Same for user yyyy. He can telnet to domain xxxx (or the IP of the server), but need to use his username and password to login.

    On every mailserver, you are able to connect with all domain names that resolve to this server as the domain does not matter as long as the IP points to the same server.

    By the way, it is the same for SSH, FTP, SMTP etc.

    Thats not correct as you dont login to a different mailserver. As long as both domains are hosted on the same server, you login to the same mailserver.
