ProcedureHow to Add Entries by Editing an NIS+ mail_aliases Table

You can use the aliasadm command to manage entries in an NIS+ table. To add more than two or three aliases to the table, follow these instructions.

  1. Compile a list of each of your mail clients, the locations of their mailboxes, and the names of the mail server systems.

  2. Either be a member of the NIS+ group that owns the table, or become root on the mail server, or assume an equivalent role.

    Roles contain authorizations and privileged commands. For more information about roles, see Configuring RBAC (Task Map) in System Administration Guide: Security Services.

  3. Display and edit the aliases table.

    # aliasadm -e

    This command displays the table and enables you to edit the table. The editor that you use has been set with the $EDITOR environment variable. If this variable is not set, vi is the default editor.

  4. Use the following format to type each alias on a separate line.

    alias: expanded-alias # ["option" # "comments"]

    This column is for the short form of the alias name.


    This column is for the expanded alias name.


    This column is reserved for future use.


    This column is used for comments about the individual alias, such as a name for the alias.

    If you leave the option column blank, type an empty pair of quotation marks ("") and add the comments.

    The order of the entries is not important to the NIS+ mail_aliases table. The aliasadm -l command sorts the list and displays the entries in alphabetical order.

    For more information, refer to Mail Alias Files and the aliasadm(1M) man page.
