email account on subhost

Hai

i need to create an email account for subhost... I tried creating an unix user account... But the adduser (or) useradd command is not working in subhost login even when i entered with the root login of the subhost... If i create unix user account with root login of host, then the mail account is created in the host and not in subhost... But i want it for the subhost...

How can I

:confused: :frowning: :confused:

Edit the password file and create the home directories manually, or use NIS.
