    This chapter, and <xref linkend="usage-mail-organize"/>, will
      provide you with an in-depth guide to the capabilities of
      Evolution as a mail client.  For information about how to set up
      your mail account, see <xref linkend="config-prefs-mail"/>.

      If you chose IMAP mail during the setup process, you must

      If you are not already viewing mail, switch to the mail tool by clicking the
      <guilabel>Email</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

          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

    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

    <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

          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.

         If the image isn't included in the message, but is, instead,

      <para>
        If you want to write in a non-Latin alphabet while using a
        Latin keyboard, try selecting a different an input method in
        the message composer. Right-click on the message composition
        area and select from the <guimenu>Input Methods</guimenu>
      menu, then begin typing. The actual keys vary by language and
      input style. For example, the Cyrillic input method uses
      transliterated Latin keyboard combinations to get the Cyrillic
      alphabet, combining letters where necessary. "Zh" and "ya"
      produce the appropriate single Cyrillic letters, and the
      single-quote ' produces a soft-sign character.
    </para>

      <para>
        For greater language display capabilities, check your
        character settings. In both the mail composer and mail reader
        settings dialogs, you can select from dozens of character
        sets. 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.
      </para>

      <para>
        To delve a little deeper into the issue, a character set is a
        computer's version of an alphabet. One of the most popular
        early character sets was called ASCII. It consisted of 128
        numbers, letters, and assorted symbols used by computers for
        almost everything. It was convenient, and didn't take up much
        space, but it didn't handle Cyrillic, Kanjii, or other
        non-Latin alphabets. 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 sets
        (UTF-7 and 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,

       recipients.
         </para>
         <para>
            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

          <para>
            Hearkening back to the dark ages when people used

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

            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

            <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>
            Normally, you can't set text styles or insert pictures in
            emails, which is why email is often regarded as
            uncommunicative and cold, and why people often resort to
            using far too many exclamation points to convey their
            feelings.  However, most newer email programs can display
            images and text styles as well as basic alignment and
            paragraph formatting. They do this with <glossterm
            linkend="html">HTML</glossterm>, just like web pages do.

            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>
          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 <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
          message came, and where, if at all, you have removed or
          altered content.

      <title>What is Encryption?</title>
      <para>
    Encryption is an ancient method of keeping information safe
    from prying eyes. Evolution helps
    you you protect your privacy by using
    gpg, an implementation of strong

    <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.
