45 1. What is Claws Mail?
46 --------------------------
48 Claws Mail (previously known as Sylpheed-Claws) is a lightweight and
49 highly configurable email client and news reader based on the GTK+
50 GUI toolkit, it runs on the X Window System.
52 Claws Mail is free software distributed under the GNU GPL.
54 To run Claws Mail use 'claws-mail' on the command line.
56 When claws-mail is executed for the first time a configuration
57 'Wizard' will appear prompting you for the minimum information
58 necessary to create a new account.
64 Claws Mail' capabilities are extended by plugins. It comes with
65 the following plugins included, all of which are built automatically
66 if the required libraries are present.
68 Plugins are installed in $PREFIX/lib/claws-mail/plugins/
69 and have a suffix of '.so'
70 To load a plugin go to '/Configuration/Plugins' and click
71 the 'Load Plugin' button.
72 Select the plugin that you want and click 'OK'
75 Enables the scanning of message attachments in mail
76 received from a POP, IMAP or LOCAL account using Clam
77 AntiVirus. It can optionally delete the mail or save it
78 to a designated folder. Preferences can be found in
79 '/Configuration/PreferencesPlugins/Clam AntiVirus'.
80 Clam AntiVirus is available from http://clamav.sourceforge.net/
83 Enables the viewing of html messages using the Dillo web
84 browser, version 0.7.0 or newer. It uses Dillo's --local
85 option by default for safe browsing. Preferences can be
86 found in '/Configuration/Preferences/Plugins/Dillo Browser'.
87 Dillo is available from http://www.dillo.org/
90 Handles core PGP functions and is required by the PGP/Inline
92 Uses GnuPG/GPGME, <ftp://ftp.gnupg.org/gcrypt/gpgme/>
95 Handles inline PGP signed and/or encrypted mails. You can
96 decrypt mails, verify signatures or sign and encrypt your
97 own mails. Uses GnuPG/GPGME, <ftp://ftp.gnupg.org/gcrypt/gpgme/>
100 Handles PGP/MIME signed and/or encrypted mails. You can
101 decrypt mails, verify signatures or sign and encrypt your
102 own mails. Uses GnuPG/GPGME, <ftp://ftp.gnupg.org/gcrypt/gpgme/>
105 Enables the scanning of incoming mail received from a POP,
106 IMAP or LOCAL account using SpamAssassin. It can optionally
107 delete mail identified as spam or save it to a designated
108 folder. Preferences can be found in '/Configuration/
109 Preferences/Plugins/SpamAssassin'.
110 SpamAssassin is available from http://spamassassin.apache.org/.
113 Places an icon in the system tray that indicates whether
114 you have any new mail. A tooltip also shows the current
115 new, unread and total number of messages
117 Additonal plugins can be found here:
118 http://www.claws-mail.org/plugins.php
123 The "actions" feature is a convenient way for the user to launch external
124 commands to process a complete message file including headers and body or
125 just one of its parts. It allows also the use of an external command to
126 filter the whole text or just a selected part in the message window or in
127 the compose window. This is a generic tool that allows to do any uncommon
128 actions on the messages, and thus extends the possibilities of Claws Mail.
129 For example, Claws Mail does not include the rot13 cyphering algorithm
130 popular in some newsgroups. It does not support uuencoded messages. As
131 all these features can be handled by external programs, the actions
132 provide a convenient way to use them from the menu bar.
137 To create a new action, go to Configuration -> Actions.... The "Action
138 Creation" dialog offers to enter the Menu name that will trigger the
139 command. The created menu will be found in the Tools -> Actions submenu.
140 By inserting a slash / in the menu name, you create a submenu.
142 The command is entered in the Command line entry. Note that Claws Mail
143 stores every single email in a separate file. This allows to use the
144 following syntax for the command:
146 * %f denotes the file name of the selected message. If you selected more
147 than one, then the command will be launched for each message with
148 the appropriate file name
149 * %F denotes the list of the file names of the selected message. If only
150 one message is selected, this amounts to %f, but if more messages
151 are selected, then the command will be launched only once with the
152 list of the file names. (You can use both %f and %F in one command:
153 then the command will be launched for each selected message with
154 the name of this message and with the list of all selected
155 messages. I did not find a practical example for this.)
156 * %p denotes the current selected message part of a multipart message.
157 The part is decoded accordingly. If the message is not a multipart
158 message, it denotes the message body.
159 * Prepending >: this will allow you to send to the command's standard
160 input a text that you will enter in a dialog window.
161 * Prepending *: this will allow you to send to the command's standard
162 input a text that you will enter in a dialog window. But in
163 contrast to prepending >, the entered text is hidden (useful when
165 * Appending an ampersand &: this will run the command asynchronously.
166 That means "fire and forget". Claws Mail won't wait for the
167 command to finish, nor will it catch its output or its error
169 * Prepending the vertical bar | (pipe-in): this will send the current
170 displayed text or the current selected text from the message view
171 or the compose window to the command standard input. The command
172 will silently fail if more than one message is selected.
173 * Appending the vertical bar | (pipe-out): this will replace the current
174 displayed text or the current selected text from the message window
175 or the compose window by the command standard output. The command
176 will silently fail if more than one message is selected.
178 Note: It is not possible to use actions containing %f, %F or %p from the
181 When a command is run, and unless it is run asynchronously, Claws Mail
182 will be insensitive to any interaction and it will wait for the command to
183 finish. If the command takes too long (5 seconds), it will popup a dialog
184 window allowing to stop it. This dialog will also be displayed as soon as
185 the command has some output: error messages or even its standard output
186 when the command is not a "pipe-out" command. When multiple commands are
187 being run, they are run in parallel and each command output is separated
188 from the outputs of the others.
193 Here are some examples that are listed in the same syntax as used for
194 storing the actions list. You can copy and past the definition in your
195 ~/.claws-mail/actionsrc file (exit Claws Mail before). The syntax
196 is very simple: one line per action, each action contains the menu name
197 and the command line separated by a colon and a space ": "
199 Purpose: rot13 cyphering
200 Definition: Rot13: |tr a-zA-Z n-za-mN-ZA-M|
201 Details: This will apply the rot13 cyphering algorithm to the
202 (selected) text in the message/compose view.
204 Purpose: Decoding uuencoded messages
205 Definition: UUdeview: xdeview %F&
206 Details: xdeview comes with uudeview. If an encoded file is split in
207 multiple messages, just select them all and run the command.
209 Purpose: Display uuencoded image
210 Definition: Display uuencoded: uudec %f&
211 Details: Displays uuencoded files. The uudec[1] script can be found in
212 the 'tools' directory of the distribution package.
214 Purpose: Alter messages
215 Definition: Edit message: gvim -f %F
216 Details: Allows editing of any received message. Can be used to remove
217 unneeded message parts, etc.
219 Purpose: Pretty format
220 Definition: Par: |par 72Tbgjqw74bEe B=._A_a 72bg|
221 Details: par is a utility that can pretty format any text. It does a
222 very good job in indenting quoted messages, and justifying
223 text. Used when composing a message
226 Definition: Part/Dillo: dillo %p&
227 Details: Browse the selected message part in Dillo.
230 [1] The uudec script can be found in the 'tools' directory of the
231 distribution package. It needs uudecode and ImageMagick's display. The
232 latter can be replaced by any image viewer that can get input from
233 standard input. The script could also be modified to use temporary files
234 instead of standard input.
239 Claws has support for different icon sets. Several icon sets can be
240 downloaded from http://www.claws-mail.org/themes.php
241 You will need to create a directory called 'themes' in your config
242 directory, unpack them into this directory, and then use the interface
243 to select them, /Configuration/Preferences/Display/Themes
245 This interface can also be used to install new themes.
252 b. Configuration and installation
259 The spell checker in Claws Mail requires the GNU/aspell library
260 (http://www.gnu.org/software/aspell), version 0.50 or newer.
262 You also need the dictionaries. Check GNU/aspell home page for how
263 to download and install them.
265 NB: The old dictionaries used by the old aspell will not work.
270 Spell checking is enabled automatically if the aspell executable is
271 found. If it is in unusual places, use '--with-aspell-prefix' to state
272 the path to the aspell executable. E.g., if aspell's full path is
273 /foo/bar/bin/aspell, then use:
275 ./configure --with-aspell-prefix=/foo/bar
277 The '--with-aspell-prefix=PREFIX' option will let the configure
278 script search for includes and libraries in PREFIX/include and PREFIX/lib.
280 You can also manually specify the includes and libraries path by using
281 either following options:
283 --with-aspell-includes=/foo/bar/include
287 --with-aspell-libs=/rab/oof/lib
291 The configure script summarizes the options compiled in. Check that
292 it lists 'GNU/aspell = yes'.
294 Then proceed as usual, with 'make' and 'make install'.
299 After successful compiling, you need to tell Claws Mail where your
300 dictionaries reside. The configure script should have found it, but in
301 case it did not, run 'aspell config dict-dir' on the shell to get the
302 path to the dictionaries.
304 Then run claws-mail and go to /Configuration/Preferences/Compose/Spell Checking.
305 Check the box 'Enable spell checker' and use the directory selector to select
306 the path where the dictionaries reside. Within the file selector, go to that
307 directory and select *any* file in the file lists. Click OK. Then, you should
308 be able to select your default dictionary.
310 When composing, misspelled words are highlighted. Click on any
311 highlighted word with the right mouse button to get a list of
312 suggestions. The first entry of the menu just displays the unknown
313 word. Selecting 'Accept in this session' (or hitting MOD1-Space,
314 where MOD1 is usually the ALT key) will ignore this word and accept
315 it in this message. Selecting the next entry, "Add to dictionary", which
316 is bound to MOD1-Enter combination, will add the unknown word to your
317 personal dictionary to learn it. The next entries are the suggested words.
318 The first 15 suggestions can be accessed by typing one of the first letters
319 of Latin alphabet (if this does not suit your language, please send
320 a mail to melvin.hadasht@free.fr). Aspell has a 'learn from mistake'
321 function that can be used by pressing the MOD1 key and selecting the
322 suggestion (with the keyboard or with the mouse). See GNU/aspell manual
323 §6.3 for an explanation of this feature (also called 'replacement storing').
325 If you click with the right mouse button everywhere else, or if you
326 shift-right-click even on a misspelled word, you get the
327 configuration menu. 'Check all' highlights all misspelled words.
328 With this menu, you can also change the dictionary while editing.
329 Finally, you can change the suggestion mode, and the learn from
332 Spell checking can also be done using keyboard shortcuts. In the
333 'Edit' menu of the compose window, there are two menus 'Check backwards
334 misspelled word' and 'Forward to next misspelled word'. Add to them
335 appropriate keyboard shortcuts. 'Check backwards misspelled word'
336 checks backwards from cursor position for the first misspelled word.
337 If it finds one, it displays the suggestions lists which can be handled
338 with the keyboard as described before. When the suggestion menu is
339 closed, the cursor returns to its original position to be able to
340 continue editing. The 'Forward to next misspelled word' do the same
341 thing in the other direction but moves the cursor at the end of the
342 misspelled word. This way, you can spell check easily a whole message
343 starting from its beginning and using the 'Forward to next misspelled
344 word' keyboard short cut.
347 6. Quick Search with extended search
348 ------------------------------------
349 Quick Search, with its powerful Extended search function,
350 enables searching through folder's messages.
352 Extended Search allows one to define criteria that messages must
353 have in order to match and be displayed in the summary view pane.
354 Search types titled From, Subject and To are self explanatory.
355 Search type extended allows one to use Claws Mail's powerful
356 filtering engine to select messages. Examples:
357 from regexpcase "foo"
358 subject regexp "Bug" & to regexp "claws-mail"
360 Additionally, it is possible to use simpler yet equally
361 powerfull patterns for message selections. Mutt users will
362 immediately recognise most of the available patterns:
364 Pattern Parameter Selects
365 ----------------------------------------------------
367 ag # messages whose age is greater than #
368 al # messages whose age is lower than #
369 b S messages which contain S in the message body
370 B S messages which contain S in the whole message
371 c S messages carbon-copied to S
372 C S message is either to: or cc: to S
374 e S messages which contain S in the Sender field
375 E S true if execute "S" succeeds
376 f S messages originating from user S
378 h S messages which contain header S
379 i S messages which contain S in Message-Id header
380 I S messages which contain S in inreplyto header
382 n S messages which are in newsgroup S
385 r messages which have been replied to
387 s S messages which contain S in subject
388 se # messages whose score is equal to #
389 sg # messages whose score is greater than #
390 sl # messages whose score is lower than #
391 Se # messages whose size is equal to #
392 Sg # messages whose size is greater than #
393 Ss # messages whose size is smaller than #
394 t S messages which have been sent to S
397 x S messages which contain S in References header
398 y S messages which contain S in X-Label header
401 S means regexp string
403 It is possible to use logical operators AND (&), OR (|) and
404 NOT (! or ~). Case sensitive search is achieved with %.
408 f "john beavis" messages from john beavis
409 %f "John Beavis" messages from John Beavis (case sensitive)
410 ~s foo messages which do not have foo in the subject
411 f foo & ~s bar messages from foo that do not have bar in thesubject
417 /Configuration/Preferences/Customize Toolbars lets you define the
418 toolbar you want. The configuration dialog enables you to set an icon,
419 an appropriate text, and map an action to it. Actions to choose
420 from are predefined. You can also have your "Claws Mail Actions"
421 (refer to "Actions" above) on your toolbar.
424 * Configuration->Actions
425 - add an entry "Dillo: dillo %p&"
426 * Configuration->Custom toolbar
427 - select Claws Mail Actions Feature
428 - select "Dillo: dillo %p&" from drop down list
429 - choose an icon and click ok
433 8. Partial downloading of POP3 mails
434 ------------------------------------
435 Messages over the configured size limit, (/[Account preferences]/
436 Receive/Message size limit), will be partially retrieved. These
437 messages will have a Notice View displayed (above the Message View),
438 informing of the partially retrieved state and the total size of the
439 message. The Notice View will also contain two buttons, 'Mark for
440 download' and 'Mark for deletion'. If the user clicks 'Mark for
441 download', the message will be downloaded in full at the next message
442 retrieval, (and the partial one deleted); if the user checks 'Mark for
443 deletion' it will be removed from the server after the normal delay
444 as specified in the POP3 account's 'Receive' preferences.
445 If a user moves a partially retrieved message to the Trash folder
446 it will be deleted on the server at the next retrieval after the
447 Trash folder has been emptied.
455 bold_unread (default: 1)
456 show unread messages using bold font in summary view
459 cache_max_mem_usage (default: 4096)
460 the maximum kB of memory Claws Mail should use.
461 It will try to keep the memory usage below this
462 value, but it will always use the assigned
463 amount of memory for speed gain.
465 cache_min_keep_time (default: 15)
466 the minimum time in minutes Claws Mail will keep
467 the folder cache in memory. If a cache is more
468 recent than this time it will not be freed even
469 if the memory usage is above the maximum. You
470 should probably set this value higher than your
471 mail check interval. Otherwise the cache will
472 always be freed between checks even if the folder
473 is accessed on every check, which will cause much
476 compose_no_markup (default: 0)
477 prevent italic and bold text in the Compose dialog
479 0: normal (markup) 1: no markup
481 enable_dotted_lines (default: 0)
482 Use the old dotted line look in the main window
483 GtkTreeView components, (Folder List and Message List),
484 instead of the modern lineless look.
486 enable_hscrollbar (default: 1)
487 enable horizontal scroll bar in summary view
490 enable_swap_from (default: 0)
491 display sender's email address in To column in Sent
492 folder instead of recipient's
495 folderview_vscrollbar_policy (default: 0)
496 specify the policy of vertical scroll bar of folder view
497 0: always 1: automatic 2: never
499 hover_timeout (default: 500)
500 time in milliseconds that will cause a folder tree to
501 expand during drag n drop when the mouse cover is held
504 live_dangerously (default: 0)
505 Don't ask for confirmation before definitive deletion of
508 log_error_color, log_in_color, log_msg_color, log_out_color,
510 The colours used in the log window.
512 mark_as_read_delay (default: 0)
513 Number of seconds to wait before marking an opened mail
516 respect_flowed_format (default: 0)
517 Respect format=flowed on text/plain message parts. This will
518 cause some mails to have long lines, but will fix some URLs
519 that would otherwise be wrapped.
521 skip_ssl_cert_check (default: 0)
522 Disables the verification of SSL certificates.
524 statusbar_update_step (default: 10)
525 update stepping in progress bars
527 stripes_color_offset (default: 4000)
528 Specify the value to use when creating alternately coloured
529 lines in GtkTreeView components. The smaller the value, the
530 less visible the difference in the alternating colours of the
533 textview_cursor_visible (default: 0)
534 display the cursor in the message view
537 thread_by_subject_max_age (default: 10)
538 number of days to include a message in a thread when using
539 'Thread using subject in addition to standard headers'

542 hide handles in the toolbar
545 use_stripes_everywhere (default: 1)
546 Enable alternately coloured lines in GtkTreeView components.
548 use_stripes_in_summaries (default: 1)
549 Enable alternately coloured lines in the main window
550 GtkTreeView components, (Folder List and Message List). The
551 only useful way to use this option is to set it to 0 when
552 use_stripes_everywhere is set to 1.
554 utf8_instead_of_locale_for_broken_mail (default: 0)
555 use UTF-8 encoding for broken mails instead of current
559 warn_dnd (default: 1)
560 display a confirmation dialog on drag n drop of folders
565 You will find all of these tools in the 'tools' directory:

658 Of course, you can also post to the Claws Mail-users mailing list.
660 Also, we really try to incorporate good contributions, but sometimes we
661 don't have enough time. If the contribution is really big, or requires
662 a long time to stabilise, send a mail to Paul Mangan
663 <paul@claws-mail.org>. We can probably arrange access to the
668 12. How to request features
669 ---------------------------
671 Ask around in Claws Mail-users ML. Note that some developers may
672 have already thought about your feature, may,perhaps, be implementing it,
673 or the feature was already discussed and rejected for whatever reason.
674 You might want to go ahead and hack a patch for it. (That would be very
675 cool!) Another possibility is to use the Feature Request Tracker at the
677 http://sourceforge.net/tracker/?group_id=25528&atid=384601
