<question><para>Why are my filters not applied to incoming messages of &imap; accounts?</para></question>
<answer>
<para>Normal &imap; mode does not support filtering, but the new 
disconnected &imap; account type does. You could try to use server-side
filtering (ask your admin for how to install filters on the server and in
which format), since &imap; is all about managing your email <emphasis>on the server</emphasis>.
Unfortunately, although there exists a mail filter language (Sieve, defined
in RFC3028), there is no standardized access protocol for installing or
editing server-side Sieve scripts. If such a protocol becomes available in
the future, &kmail; will most probably include support for it.</para>

<question><para>Using <application>PGP</application> or <application>GnuPG</application>
is very slow or it blocks &kmail;.</para></question>
<answer>
<para>&kmail; accesses <application>PGP</application>/<application>GnuPG</application> 
synchronously, &ie; it blocks while <application>PGP</application>/<application>GnuPG</application> 
works. This means that you might want to disable automatic retrieval 
of unknown keys from a keyserver to make &kmail; look more responsive.
If you are using <application>GnuPG</application> 1.0.7 (or better) or upgraded from an earlier 
version, then make sure to run <command>gpg <option>--rebuild-keydb-caches</option></command> 
once and <command>gpg <option>--check-trustdb</option></command> after every import or refresh. 
Both will speed up <application>GnuPG</application> immensely.</para>

<question><para>What should I know if I want to use
<application>PGP</application>/<application>GnuPG</application> with
&kmail;?</para></question>

<answer><para>&kmail; provides a simple and easy-to-use interface for the basic
 functions of these programs; still you should understand how these programs
 work and what might make their use insecure. Some important issues:</para>

<itemizedlist>
<listitem>
<para>You <emphasis>really</emphasis> should test if encryption works
before you use it. &kmail; partly relies on
<application>PGP</application>/<application>GnuPG</application>'s error strings,
which often change between different versions.</para>
</listitem>
<listitem>
<para>&kmail; will not encrypt messages with an untrusted (unsigned) public key: if you want to encrypt to such a 
key you should check the identity of the key owner and only then sign the key
with your secret key; if you do not want to or cannot check the identity
of the key owner but nevertheless want to encrypt the message then
please sign the key locally with <userinput><command>gpg</command>
<option>--lsign</option> <replaceable>keyID</replaceable></userinput>.</para>
</listitem>
<listitem>
<para>Trusting a foreign public key without checking it is not a good idea.</para>
</listitem>
<listitem>
<para>&kmail; cannot encrypt and sign attachments if you are using
the built-in OpenPGP support. For encrypted and signed attachments you need
to have <link linkend="configure-security-crypto-backends">crypto 
plugins</link> installed and configured.</para>
</listitem>
<listitem>
<para>Starting with GnuPG 1.0.7 you have to set your own key to
ultimate ownertrust: it is no longer implicitly done for you.</para>
</listitem>
</itemizedlist>
</answer>
</qandaentry>

<qandaentry> <question><para>Where does &kmail; save my settings and my
mail?</para></question> <answer> <para>Most &kmail; settings are stored in
<filename>$<envar>TDEHOME</envar>/share/config/kmailrc</filename>, where
$<envar>TDEHOME</envar> is typically <filename
class="directory">~/.kde</filename>; the identities are stored in
<filename>$<envar>TDEHOME</envar>/share/config/emailidentities</filename>
and your mail is saved in <filename
class="directory">$<envar>TDEHOME</envar>/share/apps/kmail</filename> (or
<filename class="directory">~/Mail</filename> if you upgraded from a
previous &kmail; version that used this location.) Note that some of the
files are hidden: remember to also copy those if you want to backup or
archive your mails.</para> </answer> </qandaentry>

<qandaentry id="faq-index-regeneration">
<question><para>Why did &kmail; regenerate the index of a folder?</para></question>
<answer>
<para>&kmail; regenerates the index of a folder whenever the index appears to be
out of date, &ie; whenever the contents of a folder are newer than the
index. &kmail; regenerates the index in this case in order to prevent
the loss or corruption of messages. Unfortunately, currently-deleted
messages might reappear and message flags (like important, etc.) might
be lost when the index is regenerated.</para>
<para>An outdated index can have several causes; the two most important causes
are:
<itemizedlist>
<listitem><para>Some other program modified the contents of the folder: if you want
to use &kmail; together with procmail then please read <link
 linkend="faq-procmail">this &FAQ;</link>. If you want to use &kmail; together with
another email client then please read <link 
linkend="faq-other-muas">this &FAQ;</link>.</para></listitem>
<listitem><para>If your mail folder (usually <filename class="directory">$<envar>TDEHOME</envar>/share/apps/kmail/</filename> or <filename class="directory">~/Mail</filename>)
is on a volume which is mounted via NFS and if the clock of the NFS server is ahead of the
clock of your computer then the NFS server sometimes reports a wrong
file date for the index file. In this case &kmail; assumes that the index
is outdated although in reality it is not. To fix this problem
you (or your system administrator) have to make sure that the clock of
the NFS server and the clock of your computer are always in sync. One
way to achieve this is the use of the ntp daemon.</para></listitem>

<question><para>I cannot add addresses to my address book after upgrading to KDE 3.x.</para></question>
<answer>
<para>You probably copied your old <filename>kmailrc</filename> file manually. That is not
necessary, there is a script that will do such things when you run KDE 3.x
for the first time. To fix the problem, remove the complete <quote>[AddressBook]</quote>
group and the addressbook option in group <quote>[General]</quote> in your 
<filename>kmailrc</filename> file; however, chances are you will also encounter other problems 
that the config update script would have solved.</para>
</answer>
</qandaentry>

<qandaentry id="faq-other-muas">
<question><para>Can I use &kmail; together with a different email client, &eg;
<application>mutt</application>?</para></question>
<answer>
<para>If you're using the mbox format for your folders it is not
possible to use a different email client while &kmail; is running.
With <application>mutt</application> there may also be problems
even if both programs are not running at the same time. We recommend to 
use the maildir format in this case, this should solve all problems.</para>
</answer>
</qandaentry>

<qandaentry>
<question><para>How can I convert my mailboxes from mbox to maildir?</para></question>
<answer>
<para>There is no automatic way to do that. You will have to create a new folder
in maildir format and copy the messages from the mbox folder into this
new folder. Remember to adapt any filter rules connected with the old folder before
you delete it.</para>

<question><para>How can I use a browser other than &konqueror; to
open links in messages?</para></question>

<para>Change the <guilabel>File Associations</guilabel> for HTML files
using &kcontrol;.</para>
</answer>
</qandaentry>

<qandaentry>
<question><para>How can I remove attachments from messages without removing
the message itself?</para></question>
<answer>
<para>This is currently not supported. As a workaround, move the
message to the drafts folder, double click on it in order to open
it in the composer, remove the attachments, save the message again to the
drafts folder, move it back to its folder. The disadvantage of
this workaround is that the date will be changed to the current date.
Some other headers might also be changed.</para>
</answer>
</qandaentry>

<qandaentry>
<question><para>How can I make &kmail; check for new messages at startup?</para></question>
<answer>
<para>If &kmail; should always check for new messages at startup then
enable <guilabel>Check mail on startup</guilabel> on the
<link linkend="configure-accounts-receiving">Accounts configuration page</link>.
Otherwise start &kmail; with <command>kmail <option>--check</option></command>.</para>
</answer>
</qandaentry>

<qandaentry>
<question><para>Why does &kmail; get slow / stop working when I try to
send big attachments?</para></question>
<answer>
<!-- fixme: update for 3.2 -->
<para>&kmail; is known to have problems with large attachments. We are working
on a solution for this problem for &kde; 3.2 but currently it temporarily consumes
virtual memory of about 10-15 times the size of the attachment. That
means that if you attach a 2MB file &kmail; might temporarily need about
20-30 MB of virtual memory (= RAM + swap space). If you do not have
enough virtual memory this will lead to problems.</para>
</answer>
</qandaentry>

<qandaentry>
<question><para>Where can I get a list of changes between the versions of &kmail;?</para></question>
<answer>
<para>The welcome screen lists all important changes for your version. It is displayed when you
select <menuchoice><guimenu>Help</guimenu><guimenuitem>&kmail; Introduction</guimenuitem></menuchoice>.</para>
</answer>
</qandaentry>

<qandaentry>
<question><para>Can I configure the location of my mail folder?</para></question>
<answer>
<para>Exit &kmail;, make a backup of <filename>~/.kde/share/config/kmailrc</filename>,
then open it with an editor and add &eg; <userinput>folders=/home/username/.mail</userinput>
to the <quote>[General]</quote> section. Then move all your existing folders (including
the hidden index files) to the new location. The next time you start &kmail; will use
<filename class="directory">/home/username/.mail</filename> instead of
<filename class="directory">/home/username/.kde/share/apps/kmail</filename>. Note that &kmail;
will lose its filters if you change the mail folder's location but forget
to move your existing folders.</para>
</answer>
</qandaentry>

<qandaentry>
<question><para>How can I use mail folders that are not in the normal &kmail; message folder location?</para></question>

<answer><para>To add a whole mbox mail folder use
<userinput><command>ln</command> <option>-s</option>
<filename>/somewhere/Mail/.remotedir.directory</filename> <filename
class="symlink">/home/username/share/apps/kmail/.mymailboxfile.directory</filename></userinput>.
Note that it is not possible to use links to files, only links that point
to folders will work.</para></answer>
</qandaentry>

<qandaentry>
<question><para>I'm one of those people whose mails consist of 100 quoted lines
and one line written by myself. For some reason this annoys other people. Can
&kmail; help me and make everyone's life better?</para></question>
<answer><para>Sure. Just select a short relevant part of the original mail
with the mouse before you reply. Only this part will then be quoted in your 
reply.</para></answer>
</qandaentry>

<qandaentry>
<question><para>For some messages the value in the <guilabel>Date</guilabel> field
is <guilabel>unknown</guilabel> or it is not correct.</para></question>
<answer><para>Probably the <quote>Date:</quote> header of these messages is 
broken and &kmail; cannot interpret it. That is not a bug in &kmail;
but in the software that sent the mail.</para></answer>
</qandaentry>

<qandaentry>
<question><para>My signature has two dashes above it. What's up?</para></question>
<answer>
<para>
Separating the signature from the message body with two dashes and a space
on a single line is common usage. These symbols permit mail clients who recognize 
them to trim the signatures from a reply. If your signature does not already have 
this separator, &kmail; will automatically add it.</para>
</answer>

<qandaentry>
<question><para>&kmail; fetches the same messages over and over again.</para></question>
<answer><para>This happens if you have enabled
<guilabel>Leave fetched messages on the server</guilabel>
and your POP3 server does not support the UIDL command. There is currently
no workaround besides disabling 
<guilabel>Leave fetched messages on the server</guilabel>.

<qandaentry>
<question><para>Are there any known bugs in &kmail;?</para></question>
<answer>
<para>A list of submitted bugs is linked at <ulink
url="http://kmail.kde.org/">the &kmail; homepage</ulink>. Note that not all
these bugs are valid. All in all we think that &kmail; is a very robust piece
of software.</para>
<para><warning><para>However, you should not run &kmail; while another email client is already
accessing the files in <filename class="directory">~/Mail</filename>; if you try to do so,
you might lose messages. Note that you should make backups of your messages anyway.</para></warning></para>

<question><para>&kmail; does not display <acronym>HTML</acronym> mail properly.</para></question>
<answer><para>References to external content like images, are disabled by
default, as they can be used to track whether and when you read a message.
Loading external references can be activated in the <guilabel>Security</guilabel>
tab in &kmail;'s configuration dialog; also Plugins (like <trademark
class="registered">Macromedia</trademark> <application>Flash</application>),
&Java; and JavaScript will not be displayed in &kmail; for security reasons
and there is no way to activate them.</para></answer>
</qandaentry>

<qandaentry>
<question><para>Can I use two different versions of &kmail; at the same time? Can I go
back from a current version of &kmail; to an older one?</para></question>
<answer><para>You can only run one instance of &kmail; at once. We also recommend
to stick to a certain version and not switch back and forth between different versions.
Downgrading to an older version will probably cause problems, &eg; because the index file
formats might have changed. Upgrading should never be a problem.</para></answer>

<answer><para>&kmail; tries to save your mail to 
<filename>~/dead.letter</filename> in case of a crash. The next time you start
&kmail; the mail composer should appear with your mail again; If it does not,
try to open <filename>~/dead.letter</filename> with an editor. If it does not
exist then the crash was so bad that &kmail; could not save your mail.</para></answer>

<question><para>When I try to set a folder to be mailing list-aware, it does not do
anything when receiving an email from the list.</para></question>
<answer><para>Associating a folder with a mailing list has nothing to do with
filtering the mailing list messages &mdash; you have to add a new filter rule manually; however, once you associated a folder with a mailing list you can use <menuchoice>

<question><para>My SMTP server requires authentication; Does &kmail; support this?</para></question>
<answer><para>There are two common techniques used for <acronym>SMTP</acronym> authentication:
<quote>SMTP after POP3</quote> and <quote>SMTP Auth</quote>. 
<quote>SMTP Auth</quote> can be set in the <guilabel>General</guilabel> tab
of the SMTP configuration dialog.
To use <quote>SMTP after POP3</quote> you have to collect all your messages in the
<guilabel>outbox</guilabel> and send them just after you have fetched new mail.
You can make &kmail; send the queued messages automatically with the
<guilabel>Send messages in outbox folder</guilabel> option on the 
<link linkend="configure-accounts-sending">Accounts configuration page</link>.
</para></answer>
</qandaentry>

<qandaentry id="faq-procmail">
<question><para>Can I use &kmail; and <application>procmail</application>?</para></question>
<answer><para>Yes, but it is important to do it the right way or you might lose
mail. In order to use <application>procmail</application> and &kmail; you need 
to set up &kmail; so that it will fetch new
mail from the spoolfiles in which <application>procmail</application>
drops your mail. Do <emphasis>not</emphasis> set up procmail to deliver
mail in a &kmail; folder, this  cannot work.</para>
          
<para>For each procmail spoolfile you then need to create an account
from which &kmail; will fetch new mail; you also need to make sure you
specify the right lockfile name for this account. When setting up an
account, &kmail; will do some minimal parsing on your
<filename>.procmail</filename> file, and will try to list every
spoolfile it has found, and also the lockfiles next to the
<guilabel>procmail lockfile</guilabel> item. procmail lets the user
specify lockfiles in three different ways, so there is no way to
establish a correspondence between the spoolfiles and lockfiles; so it's
really up to you to make sure you specify the right lockfile for each
spoolfile.</para>

<question><para>Can I use encryption with my normal (non-<acronym>SSL</acronym>)
POP3 account?</para></question>
<answer><para>If your POP3 server runs an

POP3 connection using the following command:</para>

<para><userinput><command>ssh</command> <option>-L 11000:127.0.0.1:110
user@host</option></userinput></para>

<para>Modify your &kmail; configuration to fetch the mail via
POP3 from <userinput>localhost</userinput> and ssh will tunnel
the connection for you.

<note><para>If non-encrypted messages have already been sent
via Internet, the only advantage of using <application>ssh</application> is
that your <emphasis>password</emphasis> will be sent encrypted to the POP3
server.</para></note>

<question><para>Does &kmail; lock the folders it uses?</para></question>
<answer><para>&kmail; does not lock the files in <filename
class="directory">~/Mail</filename>.</para>
<para>To avoid the risk of losing mail <emphasis>if using a local
account</emphasis> it is necessary to ensure that &kmail; uses the same type of
locking as your mail delivery agent.</para>

<para>There are five different locking options you can use:</para>

<itemizedlist>
<listitem><para><guilabel>Procmail lockfile</guilabel></para></listitem>
<listitem><para><guilabel>Mutt dotlock</guilabel></para></listitem>

<listitem><para><guilabel>none (use with care)</guilabel></para></listitem>
</itemizedlist>

<para><guilabel>Procmail lockfile</guilabel> will use a small utility that comes
with <application>procmail</application> called <command>lockfile</command>. You
can use this if your mail folder is in a folder where you have write
permission.  This will not work on your <filename
class="directory">/var/spool/mail/user</filename> file in most cases.  It will
create <filename>.lock</filename> files on your account when &kmail; is checking
for new mail. Please note that this will only work if
<application>procmail</application> is installed on your system.</para>

<para><guilabel>Mutt dotlock</guilabel> and <guilabel>Mutt dotlock
privileged</guilabel> will both use a small utility that comes with 
<application>mutt</application>
called <command>mutt_dotlock</command>. <guilabel>Mutt dotlock</guilabel>
can be used in the same way as the <guilabel>Procmail lockfile</guilabel>
option, with the same limitation with regards to the <filename
class="directory">/var/spool/mail/</filename> folders. However, the
<guilabel>Mutt dotlock privileged</guilabel> option can create lock files
in the <filename class="directory">/var/spool/mail</filename> folder. 
<command>mutt_dotlock</command> is a setgid program and this option will
run it in setgid mode. Please note that these options will only work if
<application>mutt</application> is installed on your system.</para>

<para><guilabel>FCNTL</guilabel> will use the
<function>fcntl()</function> system call.</para>

<warning><para>Usage of FCNTL locking might cause system lockups when the mail
spool file is on an NFS mounted device.</para></warning>

<para>If you do not want to use any locking, the <guilabel>none</guilabel> option
is what you want. However, there are risks of losing mail when no locking is
used.</para>

<qandaentry>
<question><para>I am only using &imap;, can I get rid of those Local Folders in 
the folder list or at least keep them collapsed all the time?</para></question>
<answer><para>No you can not get rid of them. The local folders function as a 
fallback when the &imap; server is unreachable. Although you only use &imap;, 
&kmail; uses the outbox for sending the messages. If we hide all local folders 
you won't be able to fix messages in the outbox which can not be send for some 
reason. But it is possible to keep the local folders collapsed. What 
you have to do is go to <menuchoice><guimenu>Settings</guimenu><guimenuitem>
Configure &kmail;...</guimenuitem></menuchoice> and go to the section Misc, 
there you can setup the folder on startup. If you change that to a folder on 
the &imap; account, the Local Folders will stay collapsed when &kmail; starts.
