1. What is Claws Mail?
--------------------------

Claws Mail (previously known as Sylpheed-Claws) is a lightweight and
highly configurable email client and news reader based on the GTK+
GUI toolkit, it runs on the X Window System.

Claws Mail is free software distributed under the GNU GPL.

To run Claws Mail use 'claws-mail' on the command line.

When claws-mail is executed for the first time a configuration
'Wizard' will appear prompting you for the minimum information
necessary to create a new account.


2. Plugins
----------

Claws Mail' capabilities are extended by plugins. It comes with
the following plugins included, all of which are built automatically
if the required libraries are present.

Plugins are installed in $PREFIX/lib/claws-mail/plugins/
and have a suffix of '.so'
To load a plugin go to '/Configuration/Plugins' and click
the 'Load Plugin' button.
Select the plugin that you want and click 'OK'

o Bogofilter
Enables the scanning of incoming mail received from a POP,
IMAP, or LOCAL account using Bogofilter. It can optionally
delete mail identified as spam or save it to a designated folder.
Bogofilter is a pure Bayesian filter, therefore it has better
speed performance than SpamAssassin but might catch less spam.
Bogofilter is available from http://bogofilter.sourceforge.net/

o Dillo HTML Viewer
Enables the viewing of html messages using the Dillo web
browser, version 0.7.0 or newer. It uses Dillo's --local
option by default for safe browsing. Preferences can be
found in '/Configuration/Preferences/Plugins/Dillo Browser'.
Dillo is available from http://www.dillo.org/

o PGP/Core
Handles core PGP functions and is required by the PGP/Inline
and PGP/MIME plugins.
Uses GnuPG/GPGME,

o PGP/inline
Handles inline PGP signed and/or encrypted mails. You can
decrypt mails, verify signatures or sign and encrypt your
own mails. Uses GnuPG/GPGME,

o PGP/MIME
Handles PGP/MIME signed and/or encrypted mails. You can
decrypt mails, verify signatures or sign and encrypt your
own mails. Uses GnuPG/GPGME,

o S/MIME
This plugin handles S/MIME signed and/or encrypted mails. You can
decrypt mails, verify signatures or sign and encrypt your own mails.

o SpamAssassin
Enables the scanning of incoming mail received from a POP,
IMAP or LOCAL account using SpamAssassin. It can optionally
delete mail identified as spam or save it to a designated
folder. Preferences can be found in '/Configuration/
Preferences/Plugins/SpamAssassin'.
SpamAssassin is available from http://spamassassin.apache.org/.

o Trayicon
Places an icon in the system tray that indicates whether
you have any new mail. A tooltip also shows the current
new, unread and total number of messages

Additonal plugins can be found here:
http://www.claws-mail.org/plugins.php


3. Actions
----------
The "actions" feature is a convenient way for the user to launch external
commands to process a complete message file including headers and body or
just one of its parts. It allows also the use of an external command to
filter the whole text or just a selected part in the message window or in
the compose window. This is a generic tool that allows to do any uncommon
actions on the messages, and thus extends the possibilities of Claws Mail.
For example, Claws Mail does not include the rot13 cyphering algorithm
popular in some newsgroups. It does not support uuencoded messages. As
all these features can be handled by external programs, the actions
provide a convenient way to use them from the menu bar.

a. Usage
--------

To create a new action, go to Configuration -> Actions.... The "Action
Creation" dialog offers to enter the Menu name that will trigger the
command. The created menu will be found in the Tools -> Actions submenu.
By inserting a slash / in the menu name, you create a submenu.

The command is entered in the Command line entry. Note that Claws Mail
stores every single email in a separate file. This allows to use the
following syntax for the command:

* %f denotes the file name of the selected message. If you selected more
than one, then the command will be launched for each message with
the appropriate file name
* %F denotes the list of the file names of the selected message. If only
one message is selected, this amounts to %f, but if more messages
are selected, then the command will be launched only once with the
list of the file names. (You can use both %f and %F in one command:
then the command will be launched for each selected message with
the name of this message and with the list of all selected
messages. I did not find a practical example for this.)
* %p denotes the current selected message part of a multipart message.
The part is decoded accordingly. If the message is not a multipart
message, it denotes the message body.
* Prepending >: this will allow you to send to the command's standard
input a text that you will enter in a dialog window.
* Prepending *: this will allow you to send to the command's standard
input a text that you will enter in a dialog window. But in
contrast to prepending >, the entered text is hidden (useful when
entering passwords).
* Appending an ampersand &: this will run the command asynchronously.
That means "fire and forget". Claws Mail won't wait for the
command to finish, nor will it catch its output or its error
messages.
* Prepending the vertical bar | (pipe-in): this will send the current
displayed text or the current selected text from the message view
or the compose window to the command standard input. The command
will silently fail if more than one message is selected.
* Appending the vertical bar | (pipe-out): this will replace the current
displayed text or the current selected text from the message window
or the compose window by the command standard output. The command
will silently fail if more than one message is selected.

Note: It is not possible to use actions containing %f, %F or %p from the
compose window.

When a command is run, and unless it is run asynchronously, Claws Mail
will be insensitive to any interaction and it will wait for the command to
finish. If the command takes too long (5 seconds), it will popup a dialog
window allowing to stop it. This dialog will also be displayed as soon as
the command has some output: error messages or even its standard output
when the command is not a "pipe-out" command. When multiple commands are
being run, they are run in parallel and each command output is separated
from the outputs of the others.

a. Examples
-----------

Here are some examples that are listed in the same syntax as used for
storing the actions list. You can copy and past the definition in your
~/.claws-mail/actionsrc file (exit Claws Mail before). The syntax
is very simple: one line per action, each action contains the menu name
and the command line separated by a colon and a space ": "

Purpose: rot13 cyphering
Definition: Rot13: |tr a-zA-Z n-za-mN-ZA-M|
Details: This will apply the rot13 cyphering algorithm to the
(selected) text in the message/compose view.

Purpose: Decoding uuencoded messages
Definition: UUdeview: xdeview %F&
Details: xdeview comes with uudeview. If an encoded file is split in
multiple messages, just select them all and run the command.

Purpose: Display uuencoded image
Definition: Display uuencoded: uudec %f&
Details: Displays uuencoded files. The uudec[1] script can be found in
the 'tools' directory of the distribution package.

Purpose: Alter messages
Definition: Edit message: gvim -f %F
Details: Allows editing of any received message. Can be used to remove
unneeded message parts, etc.

Purpose: Pretty format
Definition: Par: |par 72Tbgjqw74bEe B=._A_a 72bg|
Details: par is a utility that can pretty format any text. It does a
very good job in indenting quoted messages, and justifying
text. Used when composing a message

Purpose: Browse
Definition: Part/Dillo: dillo %p&
Details: Browse the selected message part in Dillo.


[1] The uudec script can be found in the 'tools' directory of the
distribution package. It needs uudecode and ImageMagick's display. The
latter can be replaced by any image viewer that can get input from
standard input. The script could also be modified to use temporary files
instead of standard input.


4. Icon Themes
--------------
Claws has support for different icon sets. Several icon sets can be
downloaded from http://www.claws-mail.org/themes.php
You will need to create a directory called 'themes' in your config
directory, unpack them into this directory, and then use the interface
to select them, /Configuration/Preferences/Display/Themes

This interface can also be used to install new themes.


5. Quick Search with extended search
------------------------------------
Quick Search, with its powerful Extended search function,
enables searching through folder's messages.

Extended Search allows one to define criteria that messages must
have in order to match and be displayed in the summary view pane.
Search types titled From, Subject and To are self explanatory.
Search type extended allows one to use Claws Mail's powerful
filtering engine to select messages. Examples:
from regexpcase "foo"
subject regexp "Bug" & to regexp "claws-mail"

Additionally, it is possible to use simpler yet equally
powerfull patterns for message selections. Mutt users will
immediately recognise most of the available patterns:

Pattern Parameter Selects
----------------------------------------------------
a all messages
ag # messages whose age is greater than #
al # messages whose age is lower than #
b S messages which contain S in the message body
B S messages which contain S in the whole message
c S messages carbon-copied to S
C S message is either to: or cc: to S
D deleted messages
e S messages which contain S in the Sender field
E S true if execute "S" succeeds
f S messages originating from user S
F forwarded messages
h S messages which contain header S
i S messages which contain S in Message-Id header
I S messages which contain S in inreplyto header
k # messages which are marked with color #
L locked messages
n S messages which are in newsgroup S
N new messages
O old messages
r messages which have been replied to
R read messages
s S messages which contain S in subject
se # messages whose score is equal to #
sg # messages whose score is greater than #
sl # messages whose score is lower than #
Se # messages whose size is equal to #
Sg # messages whose size is greater than #
Ss # messages whose size is smaller than #
t S messages which have been sent to S
tg S messages with tags containing S
tagged messages which are tagged
T marked messages
U unread messages
x S messages which contain S in References header
x "cmd args" messages returning 0 when passed to command
- %F is message file
y S messages which contain S in X-Label header

& logical AND operator
| logical OR operator
! or ~ logical NOT operator
% case sensitive search

all filtering expressions are allowed

# means number
S means regexp string

It is possible to use logical operators AND (&), OR (|) and
NOT (! or ~). Case sensitive search is achieved with %.
Examples:
T marked messages
U unread messages
f "john beavis" messages from john beavis
%f "John Beavis" messages from John Beavis (case sensitive)
~s foo messages which do not have foo in the subject
f foo & ~s bar messages from foo that do not have bar in thesubject


6. Custom toolbar
-----------------

/Configuration/Preferences/Customize Toolbars lets you define the
toolbar you want. The configuration dialog enables you to set an icon,
an appropriate text, and map an action to it. Actions to choose
from are predefined. You can also have your "Claws Mail Actions"
(refer to "Actions" above) on your toolbar.

Example:
* Configuration->Actions
- add an entry "Dillo: dillo %p&"
* Configuration->Custom toolbar
- select Claws Mail Actions Feature
- select "Dillo: dillo %p&" from drop down list
- choose an icon and click ok



7. Partial downloading of POP3 mails
------------------------------------
Messages over the configured size limit, (/[Account preferences]/
Receive/Message size limit), will be partially retrieved. These
messages will have a Notice View displayed (above the Message View),
informing of the partially retrieved state and the total size of the
message. The Notice View will also contain two buttons, 'Mark for
download' and 'Mark for deletion'. If the user clicks 'Mark for
download', the message will be downloaded in full at the next message
retrieval, (and the partial one deleted); if the user checks 'Mark for
deletion' it will be removed from the server after the normal delay
as specified in the POP3 account's 'Receive' preferences.
If a user moves a partially retrieved message to the Trash folder
it will be deleted on the server at the next retrieval after the
Trash folder has been emptied.


8. Hidden options
-----------------

It is recommnede that you use Clawsker to edit these options,
http://www.claws-mail.org/clawsker

addressbook_use_editaddress_dialog (default: 1)
Use a separate dialogue to edit a person's details. '0'
will use a form embedded in the addressbook's main window.
0: off 1: on

bold_unread (default: 1)
show unread messages using bold font in summary view
0: off 1: on

cache_max_mem_usage (default: 4096)
the maximum kB of memory Claws Mail should use. It will try
to keep the memory usage below this value, but it will always
use the assigned amount of memory for speed gain.

cache_min_keep_time (default: 15)
the minimum time in minutes Claws Mail will keep the folder
cache in memory. If a cache is more recent than this time it
will not be freed even if the memory usage is above the
maximum. You should probably set this value higher than your
mail check interval. Otherwise the cache will always be freed
between checks even if the folder is accessed on every check,
which will cause much disk IO.

compose_no_markup (default: 0)
prevent italic and bold text in the Compose dialog account
selector
0: normal (markup) 1: no markup

emphasis_color (default: #0000CF)
The colour used for the X-Mailer line when its value is
Claws Mail.

enable_dotted_lines (default: 0)
Use the old dotted line look in the main window GtkTreeView
components, (Folder List and Message List), instead of the
modern lineless look.
0: off 1: on

enable_hscrollbar (default: 1)

log_warn_color (default: #af0000)
log_status_ok_color (default: #00af00)
log_status_nok_color (default: #0000af)
log_status_skip_color (default: #aa00aa)
The colours used in the Network Log window.

outgoing_fallback_to_ascii (default: 1)
The outgoing encoding of a message will use 7bit US-ASCII
whenever it is suitable for the message content, ignoring
the "Outgoing encoding" option unless it is necessary.
Turning this option off forces the user-defined encoding to
be used, regardless of message content.
0: off 1: on

primary_paste_unselects (default: 0)
Causes the primary buffer to be cleared and the insertion
point to be repositioned when the middle mouse button is used
for pasting text.

update stepping in progress bars.

stripes_color_offset (default: 4000)
Specify the value to use when creating alternately coloured
lines in GtkTreeView components. The smaller the value, the
less visible the difference in the alternating colours of the
lines.

textview_cursor_visible (default: 0)
display the cursor in the message view.
0: off 1: on

thread_by_subject_max_age (default: 10)

10. How to contribute
---------------------

You are encourged to send patches via the Claws Mail bugzilla at
http://www.thewildbeast.co.uk/claws-mail/bugzilla/index.cgi
But please first read the patch guidelines here:
http://www.claws-mail.org/devel.php

If that's too troublesome, either contact Paul Mangan
or consider posting to the
Claws Mail-users mailing list.
http://www.claws-mail.org/MLs.php

Bugs can be reported with Claws' bugzilla at:
http://www.thewildbeast.co.uk/claws-mail/bugzilla/index.cgi

Of course, you can also post to the Claws Mail-users mailing list.

Also, we really try to incorporate good contributions, but sometimes we
don't have enough time. If the contribution is really big, or requires
a long time to stabilise, send a mail to Paul Mangan
. We can probably arrange access to the
Claws Mail CVS tree.



11. How to request features
---------------------------

Ask around in Claws Mail-users ML. Note that some developers may
have already thought about your feature and may, perhaps, be implementing
it, or the feature was already discussed and rejected for whatever reason.
You might want to go ahead and hack a patch for it. (That would be very
cool!) Another possibility is to add a request to our bugzilla, (severity:
'enhancement'), at
http://www.thewildbeast.co.uk/claws-mail/bugzilla/index.cgi


12. Installing Claws Mail from CVS
--------------------------------------

a. Downloading
--------------

To download the latest cvs cd to the directory where you wish to download
to and type the following information:

export CVS_RSH=ssh
cvs -z3 -d:pserver:anonymous@claws-mail.org:/ co -r gtk2 claws

Later, when you want to update your local repository, you'll just have to
go back to the 'claws' directory, and type:

export CVS_RSH=ssh
cvs -z3 update -dPR

b. Installing
-------------

To compile and install use the following commands:

./autogen.sh [add configure options as required]
make
make install [as root]

You will need a full set of development tools installed to be able to run
autogen.sh. See also ac/README.
