<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 insert
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 signature from a text file you select
<guilabel>Obtain signature text from</guilabel>-><guilabel>File</guilabel>. Enter the
filename in the <guilabel>Specify file</guilabel> edit field or click
the button to the right of it to browse your filesystem. If you want
to edit the file, click 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>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>Input
Field Below</guilabel> and enter the text
into the resultant 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>

&mdn;s are a generalization of what is commonly called a

a disposition notification to be sent and the receiver's

types include <quote>displayed</quote> (&ie; read),
<quote>deleted</quote> and <quote>dispatched</quote>

Strictly speaking, this option is not needed, since
&kmail; sends &mdn;s regardless of whether the message
could be successfully decrypted or not (the disposition
notification request resides in the unencrypted part of
the message), but it gives the security-conscious user
the choice to either send them always if requested

<para>
Apart from the options presented in the configuration dialog, some options
can only be set directly in the &kmail; configuration file or through KIOSK.
These so called <quote>hidden</quote> configuration options cannot be changed via
the normal &kmail; Settings dialog; they must be made by modifying the
configuration file using a text editor or the <command>kwriteconfig</command>
program.
</para>
<para>
The &kmail; configuration file is called <filename>kmailrc</filename>
and can be found in your home directory. The location can vary according
to your operating system or distribution, but can always be found by running
the command <userinput><command>kde4-config --path config --locate kmailrc</command></userinput>.
For the remainder of this section, assume that the configuration file is
located in <filename>/path/to/kmailrc</filename>.

Send Message Disposition Notifications with an empty sender string. Some servers might be configured to reject

a line by itself just above the option.
Note that the default setting of <quote>false</quote> strictly speaking violates Internet standards, but is
set that way for practical reasons, to avoid servers rejecting MDNs that &kmail;
generates because they think they are SPAM.
