10 Checkmail is nothing more than a smart textual menu allowing easy browsing
11 through a set of mailboxes (or maildirs), displayed together with numbers of
12 all messages and new messages. It is also able to notify the user that a new
13 mail has arrived by means of beeps, keyboard LEDs and on-screen display.
15 Checkmail can be freely used and distributed according to the terms of the GNU
16 General Public License version 2, as published by the Free Software Foundation.
18 Build requirements: libncurses, locales and iconv, and a decent C99 compiler
19 (preferably GCC). For full UTF-8 support, libncursesw is necessary. Options
20 for controlling XKB leds need libX11, on-screen display needs libX11 and OSDD.
21 See Makefile for several build-time switches.
30 arrow keys moves through the list
31 h, j, k, l vi-like movement keys also work
32 ENTER invokes mutt (or a program specified with the -m option)
33 on the current mailbox
34 TAB jumps to the next mailbox with some new messages
35 (mailboxes with higher priority are preferred)
36 ` TAB in reverse direction
37 Ctrl-R forces full reload of the list
38 (otherwise, it gets updated incrementally)
40 0...9 sets minimum priority of mailboxes to show (0=show all)
41 b, B enable/disable beeping
42 d, D enable/disable on-screen display
43 / start incremental search mode
44 <hotkey> activate a specific mailbox and invoke mutt on it
45 (hotkeys are defined as mailbox options and they override
46 the default key bindings)
50 When OSDD is installed (see http://mj.ucw.cz/linux.html#osdd), Checkmail can
51 send on-screen notifications on incoming mail. This can be enabled by the "d"
52 mailbox option. Additionally, you can customize the OSD messages using the "-s"
53 switch: "-s<key>=<value>" sets an OSD attribute (e.g., "-scolor=red" or
54 "-sduration=3000" [ms]), "-s=<text>" adds a line to the message. If no text
55 lines are defined, Checkmail uses built-in default.
57 Each <text> can contain the following formatting sequences:
59 %f sender of the highest-priority new message
60 %s subject of the same message
61 %n total number of new messages
62 %m the number of more new messages (i.e., %n-1)
63 if it is 0, the whole <text> line is skipped
64 %<width>... you can add an optional maximum width in characters
68 cm -i display just the inbox
69 cm -i '~/Mail/*_list' display inbox and all mailing lists
70 cm -i '~/Mail/*_list' -oINBOX=1t highlight the inbox and prefer it on TAB
75 - Checkmail currently does no mailbox locking, but the incremental update mechanism
76 is able to recover from mailboxes caught in the middle of mail delivery.
