<title>Description</title>
<para>&OfflineIMAP; is a tool to simplify your e-mail
reading. With &OfflineIMAP;, you can read the same mailbox
from multiple computers. You get a current copy of your
messages on each computer, and changes you make one place will be
visible on all other systems. For instance, you can delete a message
on your home computer, and it will appear deleted on your work
computer as well. &OfflineIMAP; is also useful if you want to
use a mail reader that does not have IMAP support, has poor IMAP
support, or does not provide disconnected operation.
</para>
<para>&OfflineIMAP; is <emphasis>FAST</emphasis>; it synchronizes
my two accounts with over 50 folders in 3 seconds. Other
similar tools might take over a minute, and achieve a
less-reliable result. Some mail readers can take over 10
minutes to do the same thing, and some don't even support it
at all. Unlike other mail tools, &OfflineIMAP; features a
multi-threaded synchronization algorithm that can dramatically
speed up performance in many situations by synchronizing
several different things simultaneously.
</para>
<para>&OfflineIMAP; is <emphasis>FLEXIBLE</emphasis>; you can
customize which folders are synced via regular expressions,
lists, or Python expressions; a versatile and comprehensive
configuration file is used to control behavior; two user
interfaces are built-in; fine-tuning of synchronization
performance is possible; internal or external automation is
supported; SSL and PREAUTH tunnels are both supported; offline
(or "unplugged") reading is supported; and esoteric IMAP
features are supported to ensure compatibility with the widest
variety of IMAP servers.
</para>
<para>&OfflineIMAP; is <emphasis>SAFE</emphasis>; it uses an
algorithm designed to prevent mail loss at all costs. Because
of the design of this algorithm, even programming errors
should not result in loss of mail. I am so confident in the
algorithm that I use my own personal and work accounts for
testing of &OfflineIMAP; pre-release, development, and beta
releases. Of course, legally speaking, &OfflineIMAP; comes
with no warranty, so I am not responsible if this turns out
to be wrong.
</para>
<refsect2>
<title>Method of Operation</title>
<para>&OfflineIMAP; operates by maintaining a hierarchy of
mail folders in Maildir format locally. Your own mail
reader will read mail from this tree, and need never know
that the mail comes from IMAP. &OfflineIMAP; will detect
changes to the mail folders on your IMAP server and your own
computer and bi-directionally synchronize them, copying,
marking, and deleting messages as necessary.
</para>
</refsect2>

<refsect1>
<title>Quick Start</title>
<para>If you have already installed &OfflineIMAP; system-wide,
or your system adminstrator has done that for you, your task
for setting up &OfflineIMAP; for the first time is quite
simple. You just need to set up your configuration file, make
your folder directory, and run it!
</para>
<para>You can quickly set up your configuration file. The distribution
includes a file <filename>offlineimap.conf.minimal</filename>
(Debian users
may find this at
<filename>/usr/share/doc/offlineimap/examples/offlineimap.conf.minimal</filename>) that is a basic example of setting of &OfflineIMAP;. You can
simply copy this file into your home directory and name it
<filename>.offlineimaprc</filename> (note the leading period). A
command such as <command>cp offlineimap.conf.minimal ~/.offlineimaprc</command> will do it. Or, if you prefer, you can just copy this text to
<filename>~/.offlineimaprc</filename>:
</para>
<PROGRAMLISTING>[general]
accounts = Test
[Test]
localfolders = ~/Test
remotehost = examplehost
remoteuser = jgoerzen
</PROGRAMLISTING>
<para>Now, edit the <filename>~/.offlineimaprc</filename> file with
your favorite editor. All you have to do is specify a directory
for your folders to be in (on the <property>localfolders</property>
line), the host name of your IMAP server (on the
<property>remotehost</property> line), and your login name on
the remote (on the <property>remoteuser</property> line). That's
it!</para>
<para>To run &OfflineIMAP;, you just have to say
<command>offlineimap</command> -- it will fire up, ask you for
a login password if necessary, synchronize your folders, and exit.
See? You can just throw away the rest of this finely-crafted,
perfectly-honed manual! Of course, if you want to see how you can
make &OfflineIMAP; FIVE TIMES FASTER FOR JUST $19.95 (err, well,
$0), you have to read on!

<title>Installation</title>
<para>If you are reading this document via the "man" command, it is
likely
that you have no installation tasks to perform; your system
administrator has already installed it. If you need to install it
yourself, you have three options: a system-wide installation with
Debian, system-wide installation with other systems, and a single-user
installation. You can download the latest version of &OfflineIMAP; from
<ulink url="http://quux.org/devel/offlineimap/">the &OfflineIMAP;
website</ulink>.
</para>
<refsect2>
<title>Prerequisites</title>
<para>In order to use &OfflineIMAP;, you need to have these conditions
satisfied:
</para>
<itemizedlist>
<listitem>
<para>Your mail server must support IMAP. Most Internet Service
Providers
and corporate networks do, and most operating systems
have an IMAP
implementation readily available.
</para>
</listitem>
<listitem>
<para>
You must have Python version 2.2.1 or above installed.
If you are
running on Debian GNU/Linux, this requirement will automatically be
taken care of for you. If you do not have Python already, check with
your system administrator or operating system vendor; or, download it from
<ulink url="http://www.python.org/">the Python website</ulink>.
If you intend to use the Tk interface, you must have Tkinter
(python-tk) installed. If you intend to use the SSL interface, your
Python must have been built with SSL support.
</para>
</listitem>
<listitem>
<para>
Have a mail reader that supports the Maildir mailbox format. Most
modern mail readers have this support built-in, so you can choose from
a wide variety of mail servers. This format is also known as the
"qmail" format, so any mail reader compatible with it will work with
&OfflineIMAP;.
</itemizedlist>

<title>System-Wide Installation, Debian</title>
<para>
If you are tracking Debian unstable, you may install
&OfflineIMAP; by simply running the following command as root:
</para>
<para>
<command>apt-get install offlineimap</command>
</para>
<para>
If you are not tracking Debian unstable, download the Debian .deb
package from the <ulink url="http://quux.org/devel/offlineimap/">&OfflineIMAP; website</ulink>
and then run <command>dpkg -i</command> to install the downloaded
package. Then, skip to <xref linkend="configuration" endterm="configuration-title"> below. You will type <command>offlineimap</command> to
invoke the program.
</para>
</refsect2>
<refsect2>
<title>System-Wide Installation, Other</title>
<para>
Download the tar.gz version of the package from the
<ulink url="http://quux.org/devel/offlineimap/">website</ulink>.
Then run
these commands, making sure that you are the "root" user first:
</para>
<ProgramListing>tar -zxvf offlineimap_x.y.z.tar.gz
cd offlineimap-x.y.z
python2.2 setup.py install</ProgramListing>
<para>On some systems, you will need to use
<command>python</command> instead of <command>python2.2</command>.
Next, proceed to <xref linkend="configuration" endterm="configuration-title"> below. You will type <command>offlineimap</command> to
invoke the program.
</para>
</refsect2>
<refsect2>
<title>Single-Account Installation</title>
<para>
Download the tar.gz version of the package from the
<ulink url="http://quux.org/devel/offlineimap/">website</ulink>.
Then run these commands:
</para>
<ProgramListing>tar -zxvf offlineimap_x.y.z.tar.gz
cd offlineimap-x.y.z</ProgramListing>
<para>When you want to run &OfflineIMAP;, you will issue the
<command>cd</command> command as above and then type
<command>./offlineimap.py</command>; there is no installation
step necessary.
</para>
</refsect2>

<refsect1 id="configuration">
<title id="configuration-title">Configruation</title>
<para>
&OfflineIMAP; is regulated by a configuration file that is normally
stored in <filename>~/.offlineimaprc</filename>. &OfflineIMAP;
ships with a file named <filename>offlineimap.conf</filename>
that you should copy to that location and then edit. This file is
vital to proper operation of the system; it sets everything you need
to run &OfflineIMAP;. Full documentation for the configuration file
is included within the sample file.
</para>
<para>
&OfflineIMAP; also ships a file named
<filename>offlineimap.conf.minimal</filename> that you can also try.
It's useful if you want to get started with
the most basic feature set, and you can read about other features
later with <filename>offlineimap.conf</filename>.
