You add the emal where, in ISPConfig? Have you created an email user before and deleted it, the empty the recycle bin.

If you created a system user manually before or use an username like root, the the username is blocked in ISPConfig for security reasons. Please chose another username.

When i restart my server (ubuntu) says me that i have a bad configuration in
/etc/hosts

I guess your /etc/network/interfaces must be like this:

auto eth0
iface eth0 inet static
        address 192.168.0.1
        netmask 255.255.255.0
        network 192.168.0.0
        broadcast 192.168.0.255
        gateway 192.168.0.1

auto eth1
iface eth1 inet static
        address 200.123.123.123
        netmask 255.255.255.0
        network 200.123.123.0
        broadcast 200.123.123.255
        gateway 200.123.123.123

You will have to set the gateway, netmask and nezwork for eth1 accordingly o the values you got from your ISP.
