    <para>
      If you chose IMAP mail during the setup process, you must

      how.

      Start the mail client by clicking on the
      <guibutton>Inbox</guibutton> icon in the shortcut bar, or by
      selecting a mail folder in the folder bar.  To read a message,
      select it in the message list; if you'd like to see it in its
      own window, double-click on it or press

    <application>Evolution</application> helps you work by letting you sort
    your email.  To sort by sender, subject, or date, click
    on the bars with those labels at the top of the message
    list. The direction of the arrow next to the label indicates
    the direction of the sort, and if you click again, you'll
    sort them in reverse order. For example, click once on
    <guilabel>Date</guilabel> to sort messages by date from
    oldest to newest.  Click again, and
    <application>Evolution</application> sorts the list from
    newest to oldest. You can also right-click on the message
    header bars to get a set of sorting options, and add or
    remove columns from the message list.  You can find detailed

       recipients.
         </para>
         <para>
            The simplest way to direct a message is to put the email

            field, which denotes primary recipients.  To send mail to
            more than one or two people, you can use the

            Hearkening back to the dark ages when people used
            typewriters and there were no copy machines, "Cc" stands

            <guilabel>Bcc:</guilabel> is a little more complex.  You

            <guilabel>Bcc:</guilabel> list are hidden from the other
            recipients of the message. Use it to send mail to large
            groups of people, especially if they don't know each other
            or if privacy is a concern.  If your <guilabel>Bcc:</guilabel> field is absent, click

            <title>What is a Mailing List?</title>
            <para>
              Mailing Lists are one of the most popular tools for
              group collaboration on the Internet. Here's how they work: 
              <simplelist>
                <member>
                  Someone sends a message to a single address, like
                  <email>evolution@ximian.com</email>.
                </member>
                <member>
                  That address belongs to a program that distributes
                  the message to a list of recipients.
                </member>
             </simplelist>
               The mail management program lets individuals subscribe
               to or unsubscribe from the list at will, without
               requiring the message writers to remember the addresses
               of every recipient.
            </para>
            <para>
              Mailing list servers can also let network administrators
              control mail flow, list membership, and even moderate
              the content of mailing lists.

                  or <guilabel>Header 1</guilabel> through
                  <guilabel>Header 6</guilabel> for varying sizes of
                  header from large (1) to tiny (6). Other styles
                  include <guilabel>preformat</guilabel>, to use the HTML
                  tag for preformatted blocks of text, and three types

        Located next to the text style buttons, these three
        paragraph icons should be familiar to users of most
        word processing software.  The leftmost button will
        make your text aligned to the left, the center
        button, centered, and the right hand button,
        aligned on the right side.

          The post office forwards your mail for you when you change

          The email <guilabel>Forward</guilabel> button
          works in much the same way.  It's particularly useful if you
          have received a message and you think someone else would

          to a new message (this is the default) or
          you can send it <glossterm linkend="inline">inline</glossterm> as a quoted
          portion of the message you are sending.  Attachment
          forwarding is best if you want to send the full, unaltered
          message on to someone else.  Inline forwarding is best if
          you want to send portions of a message, or if you have a
          large number of comments on different sections of the
          message you are forwarding.  Remember to note from whom the

        that people can look it up before contacting you.

        <simplelist>
          <member>
             Encrypt the entire message, so that nobody but the recipient can read it.
          </member>
          <member>
            Attach an encrypted signature to a plain text message, so
            that the recipient can read the message without decrypting it, and 
            only needs decryption to verify the sender's identity.

      If you get an encrypted message, you will need to decrypt it
      before you read it. Remember, the sender has to have your
      public key before they can send you an encrypted message.

      When you view the message,
      <application>Evolution</application> will ask you for your
      PGP password.  Enter it, and the message will be displayed
