<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>
<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>
<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>.
</para>
</refsect1>
<refsect1>
<title>Options</title>
<para>
Most configuration is done via the configuration file. Nevertheless,
there are a few command-line options that you may set for
&OfflineIMAP;.
</para>
<variablelist><title>OfflineIMAP arguments</title>
<varlistentry><term>-1</term>
<listitem><para>Disable most multithreading operations and use
solely a single-connection
sync. This effectively sets the <property>maxsyncaccounts</property>
and all <property>maxconnections</property> configuration file
variables to 1.
</para></listitem>
</varlistentry>
<varlistentry><term>-P <replaceable>profiledir</replaceable></term>
<listitem><para>Sets &OfflineIMAP; into profile mode. The program
will create <replaceable>profiledir</replaceable>
(it must not already exist). As it runs, Python profiling
information
about each thread is logged into profiledir. Please note: This option
is present for debugging and optimization only, and should NOT be used
unless you have a specific reason to do so. It will significantly
slow program performance, may reduce reliability, and can generate
huge amounts of data. You must use the <option>-1</option> option when
you use <option>-P</option>.
</para></listitem>
</varlistentry>
<varlistentry><term>-a <replaceable>accountlist</replaceable></term>
<listitem><para>Overrides the <property>accounts</property> option
in the <property>general</property> section of the configuration
file. You might use this to exclude certain accounts, or to sync
some accounts that you normally prefer not to. Separate the
accounts by commas, and use no embedded spaces.
</para></listitem>
</varlistentry>
<varlistentry><term>-c <replaceable>configfile</replaceable></term>
<listitem><para>Specifies a configuration file to use in lieu of
the default, <filename>~/.offlineimaprc</filename>.
</para></listitem>
</varlistentry>
<varlistentry><term>-d <replaceable>debugtype[,...]</replaceable></term>
<listitem><para>Enables debugging for OfflineIMAP. This is useful if
you are trying to track down a malfunction or figure out what is going
on under the hood. I suggest that you use this with
<option>-1</option> to make the results more sensible.</para>
<para><option>-d</option> requires one or more debugtypes,
separated by commas. These define what exactly will be
debugged, and include two options: <property>imap</property>
and <property>maildir</property>. The <property>imap</property>
option will enable IMAP protocol stream and parsing debugging. Note
that the output may contain passwords, so take care to remove that
from the debugging output before sending it to anyone else. The
<property>maildir</property> option will enable debugging for
certain Maildir operations.
