    Thanks, Carlos. This answer save us a lot of explanations.

    @rider2
    It's not that easy. ... and running a 'mail server' is a big responsibility that not so many are willing to take. We don't know what you mean by 'a server with suse'. If it's a dedicaded server and you don't know how to use it, it's a bad start.

    It is not even clear if you are in the right forum. Your server can as well
    be a SLES (SUSE Linux Enterprise Server). If that is the case you should go
    to the Novell forums.
    But as Carlos said, in the first place you need to know what you have or at
    least you need to know whom to ask (the person who set it up or maintains
    it).

    ok...
    the server is a dedicated server and as i know it has installed suse...i think opensuse
    the server holds a network of over 50 pc's...proxy,mail...
    the person that maintained the server is no longer available and i will have to maintain it. i know it is not easy but I think I know a little about linux and i want to learn...

    ok.
    i figured it out how to add users for the mail service.
    the server runs imapd and Squirellmail for webmail and a user made with "useradd -m username" solves this problem.
    the problem that appeared is that users can connect over ssh and i do not want that.
    after "chmod 777 username" user still can connect through ssh.
    anyone can explain what to do to restrict ssh connection?

    excuse my english but it is not my native language

    This is somewhat unrelated to your question, but I recommend you post at
    least the output from
    Code:
    cat /etc/SuSE-release
    so that everybody knows what version and what system you have (it shows id
    it is openSUSE and it show the version).
    To understand the ssh problem read the man pages for sshd
    Code:
    man sshd
    man ssh_config
    they are fairly complete.
    To give you some starting point, there is an AllowUsers option in the
    /etc/ssh/sshd_config file.
    About mail server configuration I know nothing, so I leave here.
    Hope it helps a little bit.

    You should know.

    Sigh... You need to know a lot to maintain that. It is a nightmare even to
    an experienced admin.

    Which means you are adding system users with access to all services, like
    ssh. Typically a mail server would have a method to add mail only users.
    Perhaps ldap.

    The previous admin should have left documentation.

    Code:
    cat /etc/SuSE-release
    SuSE Linux 9.3 (i586)
    VERSION = 9.3

    To understand the ssh problem read the man pages for sshd
    Code:

    man sshd
    man ssh_config

    they are fairly complete.
    To give you some starting point, there is an AllowUsers option in the
    /etc/ssh/sshd_config file.
    I looked in sshd_config file and is no AllowUsers option.
    When I created the new account I set the group the same as the other users where, and still can login over ssh.

    About mail server configuration I know nothing, so I leave here.
    How can I find out more about mail server? I know it runs Imap and SquirrelMail.

    Typically a mail server would have a method to add mail only users.
    Perhaps ldap.
    Probably yes, but how to find out?

    And about Yast, someone told me not to use it because it can create problems.Or Yast2.
    It is installed. What problems it can create?
