<para>&kmail; offers an import tool for the messages and address books of some other email clients. You can access it using <menuchoice><guimenu>Tools</guimenu> <guimenuitem>Import...</guimenuitem></menuchoice>. Please make sure that you compact your folders in the other email client, no matter if you are going to use the import utility or if you are going to copy files manually. You only need to read this chapter if this tool does not work for you.</para>
<para>This section is for all of the users who need to move email messages from their previous email client over to &kmail;. &kmail; can store its messages using <quote>mbox</quote> or <quote>maildir</quote> formats, which are the most widely-used mailbox formats on &UNIX; systems. Mbox mailboxes store messages in one file, identifying where messages start and end with a <literal>From</literal> line (do not mix this up with the <literal>From:</literal> header that contains the message's sender); Maildir uses one file per message. For many &UNIX; email clients, all you must do is move your mailboxes to <filename class="directory">~/Mail</filename> (or make <filename class="symlink">Mail</filename> a symbolic link to the folder containing your mailboxes), make sure they are writable by your user, and launch &kmail;. The mailboxes should now show up correctly in &kmail;.</para>
<para>Please have a look at the <ulink url="http://kmail.kde.org/tools.html">Tools section of &kmail;'s homepage</ulink> first, to see if there is a tool that imports your mailbox and maybe even address book.</para>
<warning><para>Do not use a second email client that accesses the files in <filename class="directory">~/Mail</filename> while &kmail; is running or you might lose messages. This section only explains how to import mailboxes to &kmail; once; it is not useful to you if you're planning to use several email clients for your mailboxes in the future.</para></warning>
<para><application>Eudora</application> uses the mbox format in its mail files. To use them with &kmail;, make sure that your <application>Eudora</application> mailboxes have been compacted, then copy the <literal role="extension">.mbx</literal> files (&Windows; <application>Eudora</application>) or <application>Eudora</application> mailbox files (&Mac; <application>Eudora</application>) to your <filename class="directory">~/Mail</filename> folder. You do not need to copy the <filename>index</filename> files. Once you start &kmail;, the mailboxes should appear in the Folders pane and the messages should be accessible in the Headers pane.</para>
<para>If messages do not appear in the Headers pane, your mailbox files may still contain &Windows; or &Mac; line-feed characters. Use your favourite text editor, the <application>recode</application> command or a scripting language to change the &Windows; or &Mac; line feeds to &UNIX; line feeds.</para>
<para><application>Mailsmith</application> runs on &Mac; and uses its own database format; however it is possible to export mail into mbox format using <menuchoice><guimenu>File</guimenu><guimenuitem>Export Mail</guimenuitem></menuchoice> on a selected mailbox or on selected messages. Once the messages have been exported, translate the &Mac; line breaks to &UNIX; line breaks using your favourite editor, or using the following command under &Linux;:</para>
<para>&kmail; will only recognise mboxes placed directly in the <filename class="directory">~/Mail/</filename> folder. This means that a folder hierarchy cannot be preserved by simply moving files into the <filename class="directory">~/Mail/</filename> folder, but will need to be reconstructed within &kmail; manually.</para>
<para>This format is close enough to the mailbox format that &kmail; should be able to use these mailboxes if you just copy them to your <filename class="directory">~/Mail</filename> folder; however, MMDF mailboxes have not been tested with &kmail;, so your results may vary. If you can get this format to work with &kmail;, please let us know so we can include more specific directions in the next documentation release.</para>
<para>MH mailboxes are directories containing files that correspond to each message in that mailbox. A shell script to convert MH mailboxes to mbox mailboxes, <command>mh2kmail</command>, is included at least in the source releases of &kmail;, but maybe not in the packaged releases. Running this script on a MH folder will convert it to an mbox file. We strongly suggest that you back up your MH mail folders before you use this script.</para>
<para>If you are using &Netscape; 4.x, the mail files should be found in <filename class="directory">~/nsmail</filename>; if you are using &Netscape; 6.x, they're buried in a folder deep in the <filename class="directory">~/.mozilla</filename> subfolder, something like: <filename class="directory">/home/user_name/.mozilla/user_name/2ts1ixha.slt/Mail/Mail/server_name</filename> (the <filename class="directory">2ts1ixha.slt</filename> string will probably vary, so check it on your own system.) The <filename class="directory">[...]/Mail/Mail</filename> folder contains one subfolder for each account from which you receive mail through Netscape (⪚ <filename class="directory">[...]/Mail/Mail/math.university.edu</filename>); you will need to copy files from each of them if you want everything to be accessible under &kmail;.</para>
<para>If you have no subfolders, just copy all of the &Netscape; files to <filename class="directory">~/Mail</filename>, make sure that they are writable (only by your user, of course) and restart &kmail;: all of the messages will now appear in &kmail; folders. (Note that if you use a command like <command>cp <parameter>*</parameter> <parameter>~/Mail</parameter></command>, you should follow it with <command>rm <option>-f</option> <parameter>~/Mail/*.msf</parameter></command>; every &Netscape; 6 folder has a corresponding <filename>.msf</filename> file, and if you do not get rid of them you will have a bunch of spurious empty folders).</para>
<para>If you were using subfolders under &Netscape; (⪚ a main folder called <replaceable>Work</replaceable> with subfolders called <replaceable>Jim</replaceable> and <replaceable>Nancy</replaceable>), there are additional steps required. First, create the main folder (<replaceable>Work</replaceable>) in &kmail; and create a temporary child folder under it (by right-clicking on the folder name and selecting <guilabel>Create child folder</guilabel>); it does not matter what you call this folder -- <replaceable>dummy</replaceable> or the default <replaceable>unnamed</replaceable>, for example. Once a child folder has been requested, &kmail; creates a hidden folder in <filename class="directory">~/Mail</filename> called (in this example) <filename class="directory">.Work.directory</filename>. You can then copy your &Netscape; subfolder files (<replaceable>Jim</replaceable> and <replaceable>Nancy</replaceable>) into <filename class="directory">~/Mail/.Work.directory</filename>, and restart &kmail;; the child folders will appear under the main folder <replaceable>Work</replaceable>. Of course, this procedure may be extended for sub-subfolders, to any depth. (You can remove the temporary child folders afterwards, unless it amuses you to have a <replaceable>Work</replaceable> subfolder called <replaceable>dummy</replaceable>).</para>
<para><application>Pegasus</application> for win32 uses single files for Mail folders similar to &kmail;. <application>Pegasus mail</application> folder files have the extension <literal role="extension">.pmm</literal> but they are the same format as mbox except the messages do not start with the <literal>From</literal> header, but with a control character. To work around this, replace each instance of the control character with <literal>From aaa@aaa Mon Jan 01 00:00:00 1997</literal>. This <literal>From</literal> line should be the first line of every message, before the <literal>Received:</literal> and other headers. Make sure to use a text editor that lets you save the files in &UNIX; format or create new folders in <application>Pegasus</application> that are in &UNIX; format and copy your messages there.</para>
<para>Tools to convert these formats are available at the <ulink url="http://kmail.kde.org/tools.html">Tools section of &kmail;'s homepage</ulink>.</para>
<para>First you should have a look at <ulink url="http://kmail.kde.org/tools.html">Tools section of &kmail;'s homepage</ulink> if there are tools to convert your messages.</para>
<para>Mail programs not listed here or on the homepage probably do not work with &kmail; as they use proprietary mail formats that &kmail; cannot understand. However, there is no harm in trying! If the mailbox file looks similar to the mbox format, try copying the mailbox file (remember, the index file is not needed) to your <filename class="directory">~/Mail</filename> folder and see what happens if you start &kmail;. If you get mailboxes from your favorite email client to work in &kmail;, please tell us how you did it so that we can include directions in a future revision of this documentation. </para>
