 <title>The Main Window</title>
 
 <para>The main window is the window that appears
 when &kmail; is started. It is by default divided into three panes:</para>
 
 <variablelist>
 <varlistentry>
 <term>Folder List (on the left)</term>
 <listitem>

   </mediaobject>
 </screenshot>
 <para>&nbsp;</para> <!-- whitespace -->
 
 <para>This pane contains the list of your message folders (other email programs
 may call them mailboxes). To select a folder, simply click on
 it. The message header information contained in the folder will then appear in the Message List
 pane. The folder list can be displayed in both a short view, which takes up only
 a small portion of the left side of the screen, and a long view, which takes up the 
 entire left side of the screen (and can show more folders). You can toggle
 between these two views by using the <guilabel>Appearance</guilabel>/<guilabel>Layout</guilabel> tab
 in the <menuchoice><guimenu>Settings</guimenu><guimenuitem>Configure
 &kmail;...</guimenuitem></menuchoice> dialog. The top section of the folder pane provides quick links
 to your favorite folders. Drag and drop folders here, or add them via the &RMB; context menu item <guimenuitem>Add Favorite Folder</guimenuitem>.
 Please see the <link linkend="folders">Folders Section</link> for more details about folders.</para>

 <para>This pane lists header information (Subject, Sender, and Date)
 for the messages in the currently selected folder. Clicking on an item in the Message List
 will select that message and display it in the Preview pane; you can also select
 more than one message by holding down the &Ctrl; key (or the &Shift; key) when clicking on messages.</para>
 
 <para>Change the appearance of your message list by selecting <menuchoice><guimenu>View</guimenu><guimenuitem>Message List</guimenuitem>
 <guimenuitem>Theme</guimenuitem></menuchoice>. You have several options here.
 </para>
 <itemizedlist>
   <listitem><para><guilabel>Classic</guilabel> A simple, backward compatible single row with clickable sort columns.</para></listitem>
   <listitem><para><guilabel>Smart</guilabel> A smart multi-line, multi-item list with status icons, and no sort columns.</para></listitem>
   <listitem><para><guilabel>Smart with Clickable Status</guilabel> A smart multi-line, multi-item list with clickable status icons.</para></listitem>
   <listitem><para><guilabel>Configure...</guilabel> Allows you to customize your own Message List Theme (&eg; add or remove columns from the clickable sort bar.)</para></listitem>
 </itemizedlist>
 <para>
 If you have chosen the Classic theme, you may sort the messages by clicking on the column that you wish to sort;
 if you click on the same column again, the sort order will toggle between ascending/descending. Clicking the &RMB; on the list header shows a pop up menu,
 which allows you to show or hide several columns in the list. You can customize the columns visible on the sort bar;
 see <link linkend="customize-messagelist-theme">Configure Appearance of Message List</link> for details.

 <anchor id="the-preview-pane-headers" />
 <para>This pane displays the currently selected message. Here are some ways to adjust the Preview pane.</para>
 <para>The top of the Preview pane displays the message headers. Several display options are available. Go to 
 <menuchoice><guimenu>View</guimenu><guisubmenu>Headers</guisubmenu></menuchoice>
 and try them out until you find one you like!</para>
 <itemizedlist id="using-header-options">
   <listitem><para><guilabel>Fancy Headers</guilabel> Colorful header with a spam status / attachments notification.</para></listitem>
   <listitem><para><guilabel>Brief Headers</guilabel> Title, and in parentheses: From, CCs (if any), and the date.</para></listitem>
   <listitem><para><guilabel>&kmail; 5.2</guilabel> An avatar (if available) with Title, From, To, CCs (if any), and spam status
     / attachments on separate lines.</para></listitem>
   <listitem><para><guilabel>Download New Themes...</guilabel> Allows you to download custom themes created by other &kmail; users.</para></listitem>
 </itemizedlist>
 <para>Click on the bar located on the left hand side of the pane to toggle between plain text and &HTML; (if and only if the message is coded both ways).
 The text on the bar will inform you which view you are in. The <menuchoice><guimenu>Settings</guimenu><guimenuitem>Configure
 &kmail;...</guimenuitem><guisubmenu>Security</guisubmenu></menuchoice> dialog allows you to select HTML as the default message
 display option, if you prefer &HTML; to plain text.</para>
 <para>If you would like to change the way your attachments appear in your messages, go to <menuchoice><guimenu>View</guimenu>
 <guisubmenu>Attachments</guisubmenu></menuchoice>.
 These are your options.</para>
 <itemizedlist id="using-attachment-view-options">
   <listitem><para><guimenuitem>As Icons</guimenuitem>, all attachments appear as icons at the bottom of the message.</para></listitem>
   <listitem><para><guimenuitem>Smart</guimenuitem> will show attachments as icons, unless the message suggests that they should be displayed inline.
     You can suggest that certain attachments should be shown inline in messages you compose by selecting <guilabel>Suggest automatic display</guilabel>
     in <link linkend="the-composer-window">the composer window</link> via the attachment's properties dialog.</para></listitem>
   <listitem><para><guimenuitem>Inline</guimenuitem> shows the contents of the attachments at the bottom of the message.
     Attachments that cannot be displayed, &eg; compressed files, will still be shown as an icon.</para></listitem>
   <listitem><para><guimenuitem>Hide</guimenuitem> will not show attachments.</para></listitem>
   <listitem><para><guimenuitem>In Header Only</guimenuitem> will suppress inline displays, but list the attachments along with
     the message headers.</para></listitem>
 </itemizedlist>
 <para>The interactions among the header themes, the attachment views, and the plain text versus &HTML; preferences is rather complex.
 For example, if you attach an HTML file to a plain text message, &kmail; will probably interpret your message as being coded in two
 different formats, even though this is not really the case. Similarly, &HTML; messages may display embedded images even when you have
 selected the "Hide" option for attachments.</para>
 
 <para>The structure of each message can be displayed by pressing <keycombo 
   action="simul">&Ctrl;&Alt;<keycap>D</keycap></keycombo>. This will open a message structure viewer below the preview pane.
   Turn the message structure viewer off by pressing the same three keys.</para>
 
 <para>You can scroll through the message page-by-page using the &PgUp; and &PgDn; keys, or line-by-line using the
 &Up; and &Down; keys; you can also use <link linkend="keyboard-shortcuts">keyboard shortcuts</link>
 to skip through your messages without having to use the mouse.</para></listitem>

 <para>Two mouse actions deserve mention here. First, you can select multiple noncontiguous messages to be processed
 all at once (&eg; copied, deleted, or moved) by pressing &Ctrl; and selecting them with the &LMB;. Second, you
 can open a message in an external window by double-clicking an item in the message list. If the message is in 
 the outbox, drafts, or templates folder, it will be opened in a composition window. Otherwise, it will be opened
 with the external message viewer, an abbreviated version of &kmail;'s main window without the folder and 
 message lists, and with shorter menus.</para>

 <title>Creating &HTML; Messages</title>
 
 <para>Note that &HTML; messages are often regarded as an annoyance; therefore,
 you should use &HTML; messages judiciously. In particular, you should never
 send &HTML; messages to mailing list recipients unless &HTML; messages are explicitly
 allowed.</para>
 
 <para>To create &HTML; messages, you must first enable
 the markup tools. To do this, enable <guimenuitem>Rich Text Editing</guimenuitem>
 in the <menuchoice><guimenu>Options</guimenu></menuchoice> menu, or click on
 the <guiicon><inlinemediaobject><imageobject><imagedata fileref="preferences-desktop-font.png"
 format="PNG"/></imageobject></inlinemediaobject> Rich Text</guiicon> icon on the &kmail; toolbar.
 An additional toolbar with several formatting tools will appear. Via the &HTML; toolbar you can choose
 standard text or bulleted / numbered lists. (Use the <guilabel>None <inlinemediaobject><imageobject>
 <imagedata fileref="go-down.png" format="PNG"/></imageobject></inlinemediaobject></guilabel>
 drop-down list at the left edge of the toolbar to control the style of bulleted / numbered lists.)
 You can also control the font family, the font size, the font style (bold,
 italic, underlined, or strike-through) and the text / background color. And you can specify
 the alignment of the text (left aligned, centered, right aligned, or justified) and
 insert anchor tags (aka links), horizontal lines, images, tables, and arbitrary &HTML; code
 (although support for some of the more advanced &HTML; tags is still incomplete).</para>

 attachment. (This context menu varies a little, depending on the file type of the
 attachment.) Several options (Compress / Encrypt / Sign / Suggest Automatic Display) may
 be toggled on or off for each file attached to a message.</para>
 
 <para>Use the <guimenuitem>Properties</guimenuitem> item in the context menu to
 open the <guilabel>Attachment Properties</guilabel> dialog.
 The first field contains the attachment's &MIME; type. Just like the <guilabel>Name</guilabel>
 field, it is automatically filled with an appropriate value. Sometimes the
 &MIME; type may be wrong. You can then type in any &MIME; type or
 choose from the list of common &MIME; types. You can also select an encoding
 method for your file from the list of encoding options (normally, the default
 value works fine). Check the <guilabel>Suggest automatic display</guilabel> option 
 if you want to suggest to the recipient the automatic (inline) display of this attachment. 
 Whether this works, or not, depends on the recipient's email client,
 and on his settings.</para>
 
 <para>You can also attach public crypto keys to the message by choosing the appropriate options in the
 <menuchoice><guimenu>Attach</guimenu></menuchoice> menu. <application>GnuPG</application>

 <para>After using &kmail; for a while, you may find that you have trouble
 sorting out the new messages in your inbox when they arrive. Filters allow you
 to automatically perform certain actions on incoming messages and to manually
 perform actions on selected messages in a folder.</para>
 
 <para>Filters consist of filter criteria, whose rules are used
 to determine whether this filter should be applied to a given
 message, and a list of filter actions, which describe what is to be
 done with, or to, the message if the search pattern matches.</para>
 
 <note><para>Filters are considered one after the other,
 starting with the first filter in the list. The first one whose
 pattern matches the given message is applied; you can request that
 the remaining filters also be processed, but the default is to stop
 processing at the first matching filter. </para></note>
 
 <para>Usually, filters are used on incoming messages, but they can
 also be applied to sent messages or to an arbitrary message or group
 of messages. To selectively filter messages, select the messages you
 want to filter in the message list and either type <keycombo
 action="simul">&Ctrl;<keycap>J</keycap> </keycombo> or select
 <menuchoice><guimenu>Message</guimenu> <guimenuitem>Apply
 Filter</guimenuitem></menuchoice>. This will apply the filters (the ones that
 have been marked for manual filtering in the <link
 linkend="filter-dialog">advanced filter dialog</link>) to those messages.</para>
 
 <sect2 id="filter-quick">
 <title>Fast Filter Creation</title>
 
 <para>There are two methods for creating a filter; the quick method is
 to use <menuchoice><guimenu>Message</guimenu><guimenuitem>Create
 Filter</guimenuitem></menuchoice> and select a criterion from the submenu. This will open the filter dialog
 and present you with a new filter which has the first rule of the
 search pattern and the first action (as <guilabel>Move into Folder</guilabel>) 
 preset. In most cases, all you have to do is select the folder where the message
 should be moved, but you can, of course, edit the filter as you
 like.</para>
 
 <para>When creating a filter on mailing list messages, this method 
 will try to find a criterion that
 uniquely identifies messages from the list. If it succeeds, the guessed
 name of the list is presented in the
 <menuchoice><guimenu>Message</guimenu><guisubmenu>Create
 Filter</guisubmenu><guimenuitem>Filter on
 Mailing-List...</guimenuitem></menuchoice> menu entry.</para>
 
 <para>The second method is to manually construct a filter from scratch
 by calling the filter dialog through
 <menuchoice><guimenu>Settings</guimenu><guimenuitem>Configure 
 Filters...</guimenuitem></menuchoice>. The filter dialog is described in
 detail in the following subsection.</para>

 below for a detailed description of each search rule type.</para>
 
 <para> You can click on <guibutton>&nbsp;&plus;&nbsp;</guibutton> to get an
 additional (initially empty) rule if you want to define more complex

 <varlistentry>
 <term><guilabel>Advanced Options</guilabel></term>
 
 <listitem>
 
 <para>In this group you can define a few advanced options
 that allow you to fine tune your filtering.</para>
 
 <para>Using the first row of check boxes, you can toggle when the
 filter is applied: the <guilabel>Apply this filter to incoming messages</guilabel>
 option means that the filter is applied to messages when you receive
 them (&ie; on <guiicon><inlinemediaobject><imageobject><imagedata fileref="mail-receive.png"
 format="PNG"/></imageobject></inlinemediaobject> Check Mail</guiicon>).
 The filter can be applied to all messages, to all but online IMAP accounts, or
 to particular incoming email accounts.</para>
 <para>The <guilabel>Apply this filter to sent
 messages</guilabel> option means that the filter is applied to
 messages when you send them, and the <guilabel>Apply this filter on manual
 filtering</guilabel> option controls whether to apply this filter when
 filtering is specifically selected (&ie; via
 <menuchoice><guimenu>Message</guimenu> <guimenuitem>Apply
 Filters</guimenuitem></menuchoice>.)</para>
 <para>If <guilabel>Apply this filter to sent messages</guilabel> is checked
 the filter will be triggered <emphasis>after</emphasis> the message is sent and it will 
 only affect the local copy of the message. If the recipient's copy 
 also needs to be modified, please use <guilabel>Apply this filter before 
 sending messages</guilabel>.
 </para>
 <para>The <guilabel>If this filter matches, stop processing here</guilabel>
 check box controls whether or not the filters after
 the current filter will be processed when the current filter matches.</para>
 
 <para>If the <guilabel>Add this filter to the Apply Filter menu</guilabel>
 check box is selected, this filter will be inserted
 in the <menuchoice><guimenu>Message</guimenu> <guimenuitem>Apply
 Filter</guimenuitem></menuchoice> submenu. You can then apply this
 single filter to a message or a set of messages. If you select this option,
 you may optionally select a keyboard shortcut and insert a special icon
 to invoke this filter from the toolbar.</para>
 
 <para>Another way of applying filters is to use the
 <menuchoice><guimenu>Message</guimenu> <guimenuitem>Apply
 Filters</guimenuitem></menuchoice> menu option, which applies <emphasis>all</emphasis>
 the filters – one after another – until they are all used or one of the
 filters that matches specifies the <guilabel>If this filter matches, stop
 processing here</guilabel> option.</para>
 
 </listitem>
 </varlistentry>
 </variablelist>
 
 <note><para>Filters are automatically named unless you explicitly
 rename them using the <guibutton><inlinemediaobject><imageobject>
 <imagedata fileref="document-edit.png" format="PNG"/>
 </imageobject></inlinemediaobject> Rename...</guibutton> button.
 The dialog assumes that it should continue auto-naming the filter
 as long as the filter name starts with <quote>&lt;</quote>.
 </para>
 
 <para>If you apply filter changes, via
 <guibutton>OK</guibutton> or <guibutton>Apply</guibutton>, only the valid
 filters are actually copied to the internal filter manager.</para>
 
 <para>Similarly, empty rules and actions are removed from the pattern
 and action lists, respectively, before the filter is saved.</para>

 <symbol>&percnt;1</symbol>, &etc; stand for files representing
 the message segments. For common messages, <symbol>&percnt;0</symbol> is the
 plain text message, <symbol>&percnt;1</symbol> the first attachment and so
 on. Additionally, the whole message is fed into the program's
 <acronym>stdin</acronym>; and every occurrence of
 <symbol>&percnt;{foo}</symbol> is replaced by the content of the foo
 header. If you need to identify the message via its storage location in the
 Akonadi database, you can use the %{itemid} or %{itemurl} placeholders to
 achieve that.</para>

 <userinput>Priority</userinput> in the text field. Select the same criterion 
 in the next line and type <userinput>urgent</userinput> in the

 <para>So your filter will match all messages containing a

 Select <guilabel>Mark As</guilabel> from the first drop down box.
 A new drop down box containing a list of marker flags is shown
 to the right. Select <guilabel>Important</guilabel> from the

 </step>

 <para>Since you want this filter to <emphasis>not</emphasis>
 prevent other filters' message rules from being applied,
 carefully <emphasis>uncheck</emphasis> the

 </step>
 </procedure>
 
 <para>If you are subscribed to the (general) &kde; List, you could create a
 folder for the list (let's call it
 <replaceable>KDE-General</replaceable>) and use a filter to
 automatically transfer new messages from your inbox to your
 <replaceable>KDE-General</replaceable> folder if they came from the
 &kde; List. Here is how to create this filter:</para>
 
 <procedure>
 <title>Filtering a mailing list</title>
 <step>
 <para>Check if <menuchoice><guimenu>Message</guimenu><guisubmenu>Create
 filter</guisubmenu><guimenuitem>Filter on
 Mailing-List...</guimenuitem></menuchoice> can identify the mailing
 list (the name of the list should then appear in the menu item); in
 this case, this works and you are presented with a filter that has
 <quote>List-Id <guilabel>contains</guilabel>
 &lt;kde.kde.org&gt;</quote> preset. Then select the
 desired destination folder from the folder pull-down menu in the
 <guilabel>Filter Action</guilabel> group and that is it.</para>
 
 <para>If that does not work, think of a unique way of identifying the
 messages you want to filter. The (almost) unique property of &kde;
 List messages is that they always contain
 <quote>kde@kde.org</quote> in the
 <guilabel>To:</guilabel> or <guilabel>CC:</guilabel> field. It is not
 quite perfect, because this fails for cross-posted messages.</para>
 </step>
 <step>
 <para>Select <menuchoice><guimenu>Settings</guimenu><guimenuitem>Configure 
 Filters...</guimenuitem></menuchoice>.</para>
 </step>
 <step>
 <para>Press the <guibutton><inlinemediaobject><imageobject><imagedata fileref="document-new.png"

 filter. It will appear as <guilabel>&lt;unknown&gt;</guilabel>.</para>
 </step>
 <step>
 <para>In the <guilabel> Filter Criteria</guilabel> area, select
 <guilabel>All Recipients</guilabel> from the first drop down box,
 <guilabel>contains</guilabel> from the second drop down box, and type
 <userinput>kde@kde.org</userinput> in the text
 field.</para>
 </step>
 <step>
 <para>Skip down to the <guilabel>Filter Actions</guilabel> section. Select <guilabel>Move Into
 Folder</guilabel> from the first drop down box. Click on the folder icon and a window
 containing a list of folders will appear. Select the folder that you
 want the filtered messages to be transferred to. For this example, you would select
 <guilabel>KDE-General</guilabel>.</para>
 </step>
 </procedure>
 
 <para>You may find that you need to use more powerful criteria to
 properly filter your messages; for example, you may only want to
 filter the &kde; List messages that are written by your friend <replaceable>Fred
 Johnson &lt;fj@anywhere.com&gt;</replaceable>. This is where the rest of the
 matching criteria section comes into play:</para>
 
 <procedure>
 <title>Extending the filter</title>

 <para>Open up the <guilabel>Configure Filters...</guilabel> window and select
 the filter you just created.</para>
 </step>
 <step>
 <para>Since you want to filter all messages that have
 <replaceable>kde@kde.org</replaceable> in the
 <guilabel>To:</guilabel> or <guilabel>CC:</guilabel> field
 <emphasis>and</emphasis> that are from Fred, check the
 <guibutton>Match all of the following</guibutton> radio
 button.</para>
 </step>
 <step>
 <para>Now, go to the second search rule and select the following from
 the pull-down menus: <guilabel>From</guilabel>,
 <guilabel>contains</guilabel>. Now, type
 <userinput>fj@anywhere.com</userinput> in the text field.</para>

 <title>Filter Optimization</title>
 
 <para>It is important to realize that the order of the
 filters has an  impact on the speed of the filtering process. Here are
 some ideas which can help you to improve filter performance.
 </para>
 
 <variablelist>
 <varlistentry>
 <term>Stop filter processing as soon as possible:</term>
 <listitem>
 <para>If you know that a filter finally processes a certain class of 
 messages, please make sure to check the option <guilabel>If this filter 
 matches, stop processing here</guilabel> for the filter. 
 This will avoid the evaluation of the filter rules of all subsequent
 filters. (See the advanced options in the <link linkend="filter-dialog-id">
 Filter Dialog</link>).</para>
 <para>An example is filtering messages from mailing lists via List-Id
 header into separate folders. Having found out that a message came from 
 list A means that you can avoid checking the next filter for messages
 from list B.
 </para>
 </listitem>
 </varlistentry>
 
 <varlistentry>
 <term>Consider the costs of the evaluation of filter rules:</term>
 <listitem>
 <para>The time required to evaluate a filter rule depends on the way
 the rule is constructed. In particular, scanning for a
 substring using the <guilabel>contains</guilabel> operation is faster
 than a pattern matching using the <guilabel>matches regular
 expr.</guilabel> operation.
 </para>
 <para>Another dependency is on the amount of data which is used for the
 evaluation of a filter rule. If the rule is based on a message header,
 its evaluation should normally be much faster than the evaluation of 
 a rule based on the complete message.
 </para>
 <para>Try to keep the filter rules as simple as possible.
 </para>
 </listitem>
 </varlistentry>
 
 
 <varlistentry>
 <term>Check the order of your filters:</term>
 <listitem>
 <para>The various filter actions have different degrees of complexity. 
 The most expensive filter actions are <guilabel>Pipe Through</guilabel> 
 and <guilabel>Execute Command</guilabel>, because both need external 
 programs to be run. Placing filters containing these filter actions
 behind other filters that can reduce the number of times these complex
 actions are required is useful, if the filter logic allows
 this.</para> 
 <para>An example is filtering messages from a mailing list and detecting 
 spam messages. For the spam detection you will usually use an external 
 tool via a <guilabel>Pipe Through</guilabel> action. Filtering the messages 
 for the mailing list is done via the List-Id header. If you do not want to 
 check the messages from the mailing list for spam too, it is better to
 use the filter for the mailing list messages before the filter for the 
 spam detection. This way you avoid the expensive and slow spam check for all
 messages which were identified as mailing list messages.

 <title>Signing and Encrypting Messages with <application>GnuPG</application></title>
 
 <!--
 <note><para>There have been major changes in the way &kmail; handles 
 signing/encryption. The following introduction applies to the previous
 version of &kmail;. You can still read the introduction to get an overview
 about how to sign/encrypt messages, but the details, especially those of
 the configuration, will differ.</para></note>
 -->
 <para>This is a short introduction on how to set up &kmail;'s
 <application>GnuPG</application> (<application>&GNU; Privacy Guard</application>) support;
 it gives some hints on the use of
 <application>GnuPG</application> too. It is written for people who are beginners in
 this area; if you are familiar with the use of <application>GnuPG</application>, you can
 skip most of the steps.</para>
 
 <para>Please
 also check out the <link linkend="pgp-faq">&FAQ; item about
 <application>GnuPG</application></link>.</para>
 
 <warning><para>Attachments will not be signed/encrypted if you are using
 inline OpenPGP. To sign/encrypt attachments, you have to install GnuPG and
 some necessary libraries.
 Then, you can decide for each attachment whether it should be signed/encrypted or not.
 </para></warning>
 
 <!-- <warning><para>&kmail; has to rely on <application>GnuPG</application>'s
 output; this output is often different between different versions of 
 <application>GnuPG</application>, so it is important that you test if encryption
 really works with your setup before you start using it seriously. &kmail; might
 <emphasis>not</emphasis> warn you if something fails - enable 
 <guilabel>Show signed/encrypted text
 after composing</guilabel>.  </para></warning> --><!-- Removing this warning ... GnuPG is stable now. @dcb2020295 -->
 
 <para>To set up and use <application>GnuPG</application> support in &kmail; it is
 necessary to have <application>GnuPG</application> installed and configured
 properly. Of course, we cannot give you a full introduction to
 <application>GnuPG</application> here. We will only mention the steps you must perform
 to get <application>GnuPG</application> going. For details you should look at 
 <ulink url="https://www.gnupg.org/docs.html#guides">The &GNU; Privacy Handbook</ulink>.</para>
 
 <para>It is certainly a good idea to study the GnuPG documentation as well as an
 introduction to public key cryptography. That way you can learn a lot about
 the basic concepts, which will help you understand what is going on. Also,
 many security related issues you should know about are discussed there.</para>
 
 <sect2 id="pgp-preconditions">
 <title>Preconditions</title>
 
 <para>&kmail; expects that your <application>GnuPG</application> binary is called
 <command>gpg</command>. If this is not the case for you,
 just make a symlink.</para>
 
 <para>If you have not yet done so, you must generate a key pair (secret and public
 keys) for your identity. You may do this using &kgpg; or &kleopatra; or at the command line: 
 <userinput><command>gpg</command> <option>--gen-key</option></userinput>. Or you
 can ask &kmail; to create a new key pair when you create
 a new email account. The identity (normally your name followed by your email address
 within brackets, such as <userinput>John Doe
 &lt;john@example.com&gt;</userinput>) and your passphrase are important for the
 co-operation between &kmail; and <application>GnuPG</application>.</para>

 </varlistentry>
 
 <varlistentry>
 <term><guilabel>Store sent messages encrypted</guilabel></term>
 <listitem>
 <para>When this box is checked, sent messages are stored encrypted, as they were 
 sent. This is not recommended, as you will not be able to read the messages 
 any longer if a necessary certificate expires. (Notice that GPG keys do
 not expire, as a general rule; this caution is primarily relevant for x.509 certificate users.)</para> 
 </listitem>
 </varlistentry>
 
 <varlistentry>
 <term><guilabel>Always show the encryption keys for approval</guilabel></term>
 <listitem>
 <para>This will always open a dialog that lets you choose the keys used for
 each recipient when you are sending an encrypted message. If this
 option is off, &kmail; will show the dialog only when it cannot
 find a key for a recipient or when there are conflicting or unset encryption
 preferences.</para> 
 </listitem>

 <varlistentry>
 <term><guilabel>When saving as draft, always sign/encrypt as indicated</guilabel></term>

 </varlistentry>
 
 </variablelist>
 
 <para>Now that you have set up the encryption tool, you must tell &kmail; which
 OpenPGP key you want to use for signing and encrypting messages.
 To do this go to the <link linkend="configure-identity">Identities configuration</link>
 and set the key that should be used via the <guilabel>Cryptography</guilabel> tab in the
 identity configuration dialog.</para>
 
 <para>Now you can sign outgoing messages. To let people send you
 encrypted messages, and to let them verify your signature, you
 must send them your public key, or upload your public key to a public
 <application>GnuPG</application> key server (so people can fetch your key from the server).
 To send encrypted messages to other people, or to verify their signed
 messages, you will need their public keys. You can search for public keys on a
 public <application>GnuPG</application> key server. Or you can ask your friends
 to send you one or more of their public keys.</para>

 If &kmail; finds more than one trusted key for a recipient, it will
 display a list containing all matching keys for this recipient. In either
 case you can select the key(s) which should be used for encrypting
 this message for the recipient in question.</para>
 
 <para>If you are using a key for the first time, if there are conflicting
 Encryption Preferences, or if <guilabel>Always

 <guilabel>Security</guilabel> section of &kmail;'s configuration dialog,
 the <guilabel>Encryption Key Approval</guilabel> dialog will appear.
 You can select different keys for the recipients and can 
 set the <guilabel>Encryption Preference</guilabel> for each recipient.
 The option, <guilabel>Encrypt whenever encryption is
 possible</guilabel> (on the <guilabel>Cryptography</guilabel> tab of the
 <menuchoice><guimenu>Settings</guimenu><guimenuitem>Configure &kmail;...</guimenuitem>

 trusted key for each recipient.</para>
 
 <para>As mentioned above, you will not be able to read your own encrypted sent

 Then choose, in the composer window's menu,
 <menuchoice><guimenu>Attach</guimenu><guimenuitem>Attach Public
 Key</guimenuitem></menuchoice>. This will attach your public key – the one you are
 currently using – to the message.</para>
 
 <para>Remember that it is not perfectly safe to just sign the message to ensure
 that the receiver gets the correct key. There can (possibly) be a "man-in-the-middle"
 attack: somebody could intercept your message, change the attached key, and then sign the message with that other
 key. The recipient should verify the attached key by checking the
 key's fingerprint against the one he received in a secure way from you.
 Alternatively, just ask him to use the key he received to compose and send an encrypted
 message back to you. If your secret key decrypts that message, he has a copy of your public key. See
 the <application>GnuPG</application> documentation for further details.</para>
 
 </sect2>
 
 <sect2 id="pgp-you-received-an-encrypted-message">
 <title>You received an encrypted Message</title>
 
 <para>All you have to do is to select the message in &kmail;. You may be
 prompted for your passphrase. Then, &kmail; will decrypt the message and
 show you the plain text if the message was encrypted with your public
 key. If not, you will not be able to read it. By default, &kmail; stores messages
 encrypted, so nobody can read these messages without knowing your passphrase, or, at a minimum, your login password.</para>
 
 </sect2>
 
 <sect2 id="pgp-receiving-a-public-key">
 <title>Receiving a Public Key</title>
 
 <para>You can receive a public key as an attachment, or via http, ftp, or a floppy.
 Before you use this key to encrypt a message to the owner of the
 key, you should verify the key (check its fingerprint or look for
 trusted signatures); then, you can add this key to your public keyring
 by typing <userinput><command>gpg</command> <option>--import</option>
 <replaceable>filename</replaceable></userinput> at the command line. 
 If the key is not certified with another signature that you have already trusted,
 you cannot use it to encrypt messages unless you sign (certify) the key with your own key.

 <para>The wizard scans for known anti-spam tools on your computer. 
 It is also possible to use the results of spam checks made by your service provider,
 by evaluating header information which has been added to the messages.
 You can let the wizard prepare &kmail; to use one or more of these in parallel.
 However, note that anti-spam tool operations are unusually time consuming.
 &kmail; can appear to be frozen during the scan of messages for spam, so
 you may encounter problems with the responsiveness of &kmail;. Please consider 
 deleting the filter rules created by the wizard if the filtering becomes 
 too slow for you. (This has been a problem with older hardware. It probably won't afflict more modern machines.)</para>
 <para>Here are some observations about a few anti-spam tools.</para>
 
 <variablelist>
 <varlistentry>
   <term>Bogofilter</term>
 <listitem>
 <para>Bogofilter is a Bayesian filter. Its spam detection ability
 relies on an initial training phase. On the other hand, it's a pretty 
 fast tool. That's why it is recommended for people who 
 want fast spam detection, and who aren't worried
 about putting some effort into the initial training, before the detection rate
 increases significantly.
 </para>
 </listitem>
 </varlistentry>
 <varlistentry>
   <term>SpamAssassin</term>
 <listitem>
 <para>SpamAssassin is a fairly complex tool to use against spam.
 Although its behavior depends heavily on its configuration,
 it can detect spam quite well without any training. However,
 scanning a message takes a little longer compared to pure Bayesian 
 filters. Let's say it's not the tool of choice for people without
 some background information about SpamAssassin's capabilities.

 <varlistentry>
   <term>GMX Spam Filter</term>
 <listitem>
 <para>If you get your mail via the GMX freemail provider,
 your messages have already been scanned for spam. The result of that process is
 documented in a special header field in each message. It's possible to
 use the content of this header field to filter out spam. There is very little
 slowdown in the filtering when this tool is used, as the messages
 have already been processed by the external email server.

 <sect2 id="spam-wizard-advanced">
 <title>Advanced</title>
 
 <para>&kmail; can use several 
 external tools to detect spam messages; it will try to automatically find 
 out which tools are installed on your system, and will display all of these
 in a list. The list is ordered by the average speed of the filtering
 process of the tools. You can mark the tools which you want 
 &kmail; to utilize to detect spam. If you want more choices, you 
 can simply close the wizard, install a new tool, then restart the wizard.
 </para>
 
 <para>If you have marked at least one tool, &kmail; is able to provide filters
 which allow the classification of the messages as spam or not spam. It will 
 also provide actions to let you manually classify messages. These actions will 
 be available in the <menuchoice><guimenu>Message</guimenu><guisubmenu>Apply
 Filter &gt;</guisubmenu></menuchoice> menu item, and also via a pair of icons on the toolbar.
 If any of the tools you selected support Bayesian filtering (&ie; a method 
 to detect spam based on statistical analysis of the messages) then these 
 messages are not only marked but additionally piped through the tools to
 help them learn, thereby improving their detection rate.
 </para>
 
 <para>On the second page, you will be able to select some additional
 actions to be performed in &kmail; with regard to spam messages: if you
 want messages detected as spam to be moved into a certain folder, select
 the appropriate folder and mark the <guilabel>Move known spam to:</guilabel> 
 option; if messages detected as spam should additionally be marked as read, 
 then mark the <guilabel>Mark detected spam messages as read</guilabel> option.
 </para>
 
 <para>Selecting at least one of the available tools will allow
 the wizard to finish the filter setup. The wizard will not take any
 modifications in existing filters, formerly created by it, into
 consideration, but will either append new filters or replace existing filters.
 In any case you may want to inspect the result of this process in the
 <link linkend="filter-dialog">Filter Dialog</link>. 
 The wizard will also create toolbar buttons for marking messages as spam or
 as ham. Keep in mind that classifying messages as spam will also move those 
 messages to the folder you have specified for spam messages, when you
 select the <quote>spam</quote> option.
 </para>
 
 </sect2>
 
 <sect2 id="spam-wizard-details">
 <title>Some More Details for Experts</title>
 
 <para>The wizard uses information stored in a special configuration file named 
 <filename>kmail.antispamrc</filename> (stored in the global or local &kde;
 config directory). It will first check the global config file and then the local 
 config file. If the local config file contains an entry with a higher (newer) 
 version number, the configuration data from the local file (for that
 tool) is used, so both administrators and users can update the
 wizard's configuration.
 </para>
 
 <para>The local detection of spam messages is achieved by creating 
 <guilabel>pipe through</guilabel> actions per-tool within a 
 special filter. Another filter contains rules to check for detected spam 
 messages and actions to mark them and (optionally, depending on the choice 
 in the wizard) to move them into a folder. Both filters are configured to 
 be applied to incoming messages and for manual filtering.
 </para>
 
 <para>Two filters are needed for the classification of ham and spam. They
 contain actions to mark the messages appropriately. As mentioned above, the
 filter for classification as spam can have another supplementary action to
 move the messages into a predefined folder. If the selected tools support
 Bayesian filtering, the wizard will create additional filter actions to pass
 the messages to the tools (via <guilabel>Execute Command</guilabel> actions)
 in the appropriate learning mode.
