  .i Mail
  provides a simple and friendly environment for sending and receiving mail.
  It divides incoming mail into
  its constituent messages and allows the user to deal with them
  in any order.  In addition, it provides a set of
  .i ed -\c
  like commands for manipulating messages and sending mail.
  .i Mail
  offers the user simple editing capabilities to ease the composition
  of outgoing messages, as well as providing the ability to define and send
  to names which address groups of users.  Finally,
  .i Mail
  is able to send and receive messages across such networks as the
  ARPANET, UUCP, and Berkeley network.
  .pp
  This document describes how to use the
  .i Mail
  program to send and receive messages.  The reader is not assumed to
  be familiar with other message handling systems, but should be
  familiar with the \s-2UNIX\s0\**
  .(f
  \** \s-1UNIX\s0 is a trademark of Bell Laboratories.
  .)f
  shell, the text editor, and some of the common \s-2UNIX\s0 commands.
  .q "The \s-2UNIX\s0 Programmer's Manual,"
  .q "An Introduction to Csh,"
  and
  .q "Text Editing with Ex and Vi"
  can be consulted for more information on these topics.
  .pp
  Here is how messages are handled:
  the mail system accepts incoming
  .i messages
  for you from other people
  and collects them in a file, called your
  .i "system mailbox" .
  When you login, the system notifies you if there are any messages
  waiting in your system mailbox.  If you are a
  .i csh
  user, you will be notified when new mail arrives if you inform
  the shell of the location of your mailbox.  On version 7 systems,
  your system mailbox is located in the directory /usr/spool/mail
  in a file with your login name.  If your login name is
  .q sam,
  then you can make
  .i csh
  notify you of new mail by including the following line in your .cshrc
  file:
  .(l
  set mail=/usr/spool/mail/sam
  .)l
  When you read your mail using
  .i Mail ,
  it reads your system mailbox and separates that file into the
  individual messages that have been sent to you.  You can then
  read, reply to, delete, or save these messages.
  Each message is marked with its author and the date they sent it.
