This chapter describes the command-line version of the mail(C) program provided with SCO OpenServer systems. For information on the menu-driven SCO Shell Mail program, see ``Using SCO Shell Mail''. The graphical Desktop Mail program is described online in Using Mail.
E-mail is like a postal system, and the system mailbox
is like the post office.
The system mailbox is located in the usr/spool/mail directory,
and contains a file for each user on your system. Your own
personal or user mailbox is the file named mbox
in your home directory. Mail sent to you is put in your system
mailbox and is automatically saved in your user mailbox after you
have read it.
For further information on default mail filenames and locations,
For details on controlling
certain aspects of mail using environment variables, see
``Setting environment variables''.
