The mail system has the ability to configure user's INBOX locations. Traditional UNIX mail systems placed all user's inboxes in a fixed directory. This is inconvenient for large servers as it is often desirable to have mail inboxes located on separate disk drives and/or located in each user's home directory to concentrate all user data in a single directory on the disk drive of the administrator's choice.
There are two basic or ``canned'' locations for users' INBOXes and they are the normal system spool directory or in each user's home directory. Additionally there is a ``custom'' configuration that allows two parameters to be set, both the INBOX directory and the INBOX name. Full details of configuring users' INBOX locations are given in ``Managing the user's INBOX location''. After you exit the Mail Manager and save changes, all future incoming messages will go to the new location specified.
