<title>Signature</title>
<para>This tab allows you to specify a signature (sometimes called

to be appended to each message sent using this identity.</para>
<note><para>This type of signature has nothing to do with the
(digital) signatures for which you can select the keys to use on
the <link linkend="configure-identity-cryptography">Cryptography</link>
tab. It is just bad wording to call this a signature, but since
the term is already used everywhere else, we keep this notation. Just
keep in mind that these signatures and digital signatures are two
completely different things.</para></note>
<para>Check the <guilabel>Enable signature</guilabel> option if you
want to be able to append the signature when using this identity. To
<emphasis>automatically</emphasis> append it to every new message
you also have to select <guilabel>Automatically append
signature</guilabel> in the <guilabel>Composer</guilabel> configuration page.</para>
<para>&kmail; can obtain the signature text from various sources. The
traditional way on Unix is to read the text from a file called
<filename>.signature</filename> in your home folder. This file can
be shared between several programs, so you get the same
signature in each mail program you use.</para>
<para>To read the text from a text file you select
<guilabel>Obtain signature text from file</guilabel>. Enter the
filename in the <guilabel>Specify file</guilabel> edit field or hit
the button to the right of it to browse your filesystem. If you want
to edit the file, hit the <guilabel>Edit File</guilabel>
button.</para>
<para>&kmail; can also read the signature text from the output of a
command. Thus, you can use programs such as
<command>fortune</command> to create a new signature text for
every message. Everything the program prints onto
<acronym>stdout</acronym> is caught and used as the signature
text.</para>
<para>To read the text from the output of a command you select
<guilabel>Obtain signature text from Output of
Command</guilabel>. Enter the command (preferably with full path) in
the <guilabel>Specify command</guilabel> edit field.</para>
<para>As a third option, you can enter the signature text directly in
&kmail;'s configuration dialog. To do this, select <guilabel>Obtain
signature text from input field below</guilabel> and enter the text
into the appearing text box.</para>
<note><para>On the Internet, signatures are by convention separated
from the body of the message by a line containing only the three
character <quote>-- </quote> (dash, dash, space). &kmail; will
automatically prepend the signature text with this line if it is not
already present in the signature text.</para>
<para>If you do not wish the separator to be prepended
automatically by &kmail;, simply add it to the signature
text yourself.</para>

<para>This page allows you to create one or more (incoming and

create one outgoing (used for sending messages) and one incoming (used to

<para><guilabel>Message property</guilabel> lets you select how your
message will be encoded when it is sent. <guilabel>Allow
8-bit</guilabel> means that &kmail; will send your message in 8-bit
<acronym>ASCII</acronym>, which means that all special characters such
as accented letters will be sent as-is. If <guilabel>MIME Compliant
(Quoted Printable)</guilabel> is selected, special characters will be
encoded using standard &MIME; encodings, which may be more portable to
mailing systems other than 8-bit <acronym>ASCII</acronym>.
We recommend to use <guilabel>MIME Compliant</guilabel>.</para>
<note><para>Even with <guilabel>Allow 8-bit</guilabel>
selected &kmail; will use <guilabel>MIME

example for sending cryptographically signed messages.</para></note>
<para><guilabel>Default domain</guilabel> lets you specify which domain name
should be used to complete email addresses that only consist of the recipient's user

<title>Colors</title>
<para>This section allows you to change the color of the text.
<guilabel>Recycle colors on deep quoting</guilabel> means that even text that is

<para><guilabel>Show HTML status bar</guilabel> activates a bar at the left side of the reader
pane that tells you if a message is &html; or not. This is important because
&html; messages might imitate the look of a signed and encrypted message, so
you should be aware of the fact that you are reading a &html; message. The &html;
status bar itself cannot be influenced by the &html; code of the message.</para>
<para>The <guilabel>Window Layout</guilabel> section lets you choose the

lets you access all parts of a message. <guilabel>Show never</guilabel> will
disable the structure viewer (note that you can still access attachments as icons),
<guilabel>Show always</guilabel> will show the structure viewer even if there is only
one plaintext part. <guilabel>Show only for non-plaintext messages</guilabel> will

of the subject, every message that has been encrypted will have a small
<guiicon>Encrypted</guiicon> icon in front of the subject. Note that you have
to select a message once before these icons will appear, until then only
question marks will be displayed.</para>
<para><guilabel>Thread list of message headers</guilabel> will put all the messages
in the header pane in a kind of tree list, so that the replies to a message are
directly below that message.</para>
<para>With <guilabel>Message header threading options</guilabel> you can select
whether threads should appear expanded (<guilabel>open</guilabel>) by

Crypto Backends
</title>
<para>
On this tab you can configure which crypto backends are to be
used for &openpgp; and &smime; cryptographic operations (such
as signing and encrypting).
</para>
<para>
On the right-hand side, you see a list of available
backends. Below each backend entry, you can see what protocols
(&openpgp; and/or &smime;) the backend supports. If a protocol
is not listed, the backend does not support it. If it is
listed, but grayed out, the backend supports the protocol, but
some required programs were not found, or other errors
occurred during initialization. If you press
<guibutton>Rescan</guibutton>, a dialog box will appear that
lists reasons for the initialization failure.
</para>
<para id="configure-security-crypto-backends-configure">
To configure a backend, select it in the list of available
backends and press <guibutton>Configure...</guibutton>. The
per-backend configuration dialog is dynamically created from
the information returned by the backend. It may therefore
change if you update the backend applications, although
&kmail; itself is unchanged. If the
<guibutton>Configure...</guibutton> button is disabled, the
backend does not support a backend configuration dialog.
</para>
<para>
Please refer to the manuals of the applications underlying
each backend for a description of the options presented in the
backend configuration dialogs.
</para>
<para>
In front of each backend's protocol entries, you can see a
checkbox, with which you select which backend is to be used
for a given protocol. These checkboxes are exclusive per
protocol, meaning that if you select a backend to perform
&openpgp; operations, any previously selected &openpgp;
implementation will be unselected, but the &smime; backend
selection will be unchanged. If no backend is selected for a
given protocol, that protocol is effectively disabled for use
in &kmail;.
