      If you are not already viewing mail, switch to the mail tool by clicking the
      <guilabel>Mail</guilabel> button in the shortcut 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 <keycap>Return</keycap> or

    <para>
          You can click the space bar to page down while you're reading

          <keycap>.</keycap> (period) or <keycap>,</keycap> (comma)
          keys. On most keyboards, these  keys are also marked
          with the &gt; and &lt; symbols, which makes a convenient way
          to remember that they move you forward and backward in your
          message list. You can also use <keycap>]</keycap> (close
          bracket) for the next unread message, and <keycap>[</keycap>
          (open bracket) for the previous unread message.

      <title>Sorting the message list</title>
      <para>
    Evolution 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
    Evolution 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
    instructions on how to customize your message display
    columns in <xref linkend="usage-mail-organize-columns"/>.

    <title>Trash is Actually a vFolder?</title>
    <para>
      Both local and IMAP Trash folders are actually vFolders that
          display all messages you have marked for later deletion.
          For more information about vFolders, see <xref
          linkend="usage-mail-organize-vfolders"/>.  Since emptying
          your trash expunges the messages in your Trash folder,
          choosing <menuchoice> <guimenu>Actions</guimenu>
          <guimenuitem>Empty Trash</guimenuitem> </menuchoice> is the
          same as expunging deleted mail from <emphasis>all</emphasis>
          your folders.
    </para>
        <para>
           This is not, however, true for the Trash folder on Exchange
           servers, which behaves just the same as it would in
           Outlook. That is to say, the Trash folder on an Exchange
           server is a normal folder with actual messages in it.

        Preferences</guilabel> and <guilabel>Composer
        Preferences</guilabel> sections.  If you aren't sure which one
        to choose, go ahead and choose UTF-8, which offers the
        greatest range of character displays for the greatest range of
        languages.

      <note><title>What is a character set?</title>
    
      <para>
        A character set is a computer's version of an alphabet. In the
        past, the ASCII character set was used almost
        universally. However, it contained only 128 characters,
        meaning it was unable to display characters in Cyrillic,
        Kanjii, or other non-Latin alphabets. To get around language
        display problems, programmers developed a variety of mostly
        incompatible ways to work around their language display
        problems, and today, many human languages have their own
        specific character sets, and items written in other character
        sets will display incorrectly.  Eventually, standards
        organizations developed the Unicode character set UTF-8 to
        provide a single compatible set of codes for everyone.
      </para>

      <para>
        Most email messages state in advance which character set they
        use, so Evolution usually knows what to display for a given
        binary number. However, if you find that messages are
        displayed as rows of incomprehensible characters, try
        selecting a different character set in the mail settings
        screen. If your recipients can't read your messages, try
        selecting a different character set in the composer options
        dialog.  For some languages, such as Turkish or Korean, it may
        work best for you to select the language-specific character
        set. However, the best choice for most users is UTF-8, which
        offers the widest range of characters for the widest range of
        languages.

        Offline mode is a tool designed for use with remote mail
        storage systems like GroupWise, IMAP or Exchange,
        in situations where you will not be connected to
        the network at all times. It will keep a local copy of one or

        While POP mail downloads all messages to your local system,
        other connections usually download just the headers, and fetch
        the rest only when you want to read the message.  Before you

    <title>Specifying Extra Recipients for Email</title>
        <para>
      Evolution, like most email
       programs, recognizes three types of addressee: primary
       recipients, secondary recipients, and hidden ("blind")
       recipients.  The simplest way to direct a message is to put
          the email address or addresses in the
          <guilabel>To:</guilabel> field, which denotes primary
          recipients.  To send mail to more than one or two people,
          you can use the <guilabel>Cc:</guilabel> field.
          </para>
          <para>
            Hearkening back to the dark ages when people used
            typewriters and there were no copy machines, "Cc" stands
            for "Carbon Copy."  Use it whenever you want to share a
            message you've written to someone else.
          </para>
          <para>
            <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.

          <para>
            Some people do not have HTML-capable mail clients, or
            prefer not to receive HTML-enhanced mail because it is
            slower to download and display. Because some people may
            prefer not to get HTML mail,
            Evolution sends plain text
            unless you explicitly ask for HTML.  
           </para>

     <para> You can change the format of an email message between

                  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
                  of bullet points for the highly

        <para>
          The post office forwards your mail for you when you change
          addresses, and you can forward a letter if it comes to you by mistake.
          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
          like to see it.  You can forward a message as an attachment
          to a new message (this is the default) or
          you can send it <link linkend="inline">inline</link> 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
          message came, and where, if at all, you have removed or
          altered content.

    <title>Encryption</title>
   
      <para>
    Encryption is an ancient method of keeping information safe
    from prying eyes. Evolution helps
    you protect your privacy by using
    gpg, an implementation of strong
    <link linkend="public-key-encryption">Public Key
    Encryption.</link>
      </para>

    <note id="pub-priv">
      <title>Public Key?  Private Key?  What is the difference?</title>
      <para>
        GPG uses two keys: public and private.  You can give your
        public key to anyone you want to receive
        encrypted messages, or put it on a public key server so
        that people can look it up before contacting you.
        <emphasis>Never give your private key to anyone,
        ever</emphasis>.  Your private key lets you decrypt any
        message encrypted with your public key.
      </para>
    </note>

      <para>
        Using encryption takes a bit of forethought.  When you send a
        message that is encrypted, you must encrypt it using your
        intended recipient's public key.  To <emphasis>get</emphasis>
        an encrypted message, you must make sure that the sender has
        your public key in advance. For signing messages, it's
        reversed: you encrypt the signature with your private key, so
        only your public key can unlock it. When you send it, the
        recipient gets your public key and unlocks the signature,
        verifying your identity.
      </para>

      <para>
    You can use encryption in two different ways:
        <itemizedlist>

            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.

        <title>S/MIME Encryption</title>
        <para>
          S/MIME encrpytion uses a key-based approach as well, but it
          has some significant advantages in convenience and
          security. S/MIME uses "certificates," which are basically
          the same as keys.  The public portion of each certificate is
          held by the sender of a message and by one of several
          certificate authorities, who are paid to guarantee the
          identity of the sender and the security of the
          message. Evolution already knows a large number of
          certificate authorities, so when you get a message with an
          S/MIME certificate, your system will automatically get the
          public portion of the certificate and decrypt or verify the
          message.
        </para>
        <para>
          S/MIME is used most often in corporate settings. In these
          cases, administrators supply certificates which they have
          purchased from a certificate authority. In some cases, an
          organization can act as its own certificate authority, with
          or without a guarantee from a dedicated authority such as
          Verisign or Thawte. In either case, the system administrator
          will provide you with a certificate file.
        </para>
        <para>
          If you wish to use S/MIME independently, you can extract an
          identification certificate from your Mozilla or Netscape web
          browser. See the Mozilla help for more information on
          security certificates.
        </para>

        <para>
          The certificate file is a password-protected file on your
          computer. To use it in Evolution, select <menuchoice><guimenu>Tools</guimenu>
        <guimenuitem>Settings</guimenuitem></menuchoice> and select
        the <guilabel>Certificates</guilabel> tool in the settings
        window. Click the <guilabel>Import</guilabel> button and
        select the file when prompted.
        </para>
        <para>
          Similarly, you can add certificates which are sent to you
          independently of any authority by clicking the
          <guilabel>Contact Certificates</guilabel> tab and using the
          same <guilabel>Import</guilabel> tool. You can also add new
          certificate authorities, which have their own certificate
          files, in the same way.
        </para>
        <para>
          Once you have added your certificate, you can sign or encrypt a message by selecting <menuchoice>
