4 Some tips about how to do some useful things with notmuch, and the
5 various "third party" notmuch utilities.
7 * <span id="receive_mail">**Receive mail**</span>
9 Notmuch requires either [maildir
10 flag](http://cr.yp.to/proto/maildir.html) or a "mh"-style
11 maildirectory to operate on. Basically any setup in which each mail
12 is in a file of its own will work. Here are some generally
13 well-regarded mail retrieval tools:
15 * [offlineimap](https://github.com/nicolas33/offlineimap/) -
16 quite useful and widely tested, it also offers a handy hook that
17 will come in useful a bit later in our setup. Also supports
18 "presynchook" and "postsynchook" command that will get run
19 whenever you sync. Point _postsynchook_ to a script that gets run
20 on every sync and that will do the automatic updating and tagging
21 of your notmuch database.
23 * [mbsync](http://isync.sourceforge.net/)
25 * [getmail](http://pyropus.ca/software/getmail/)
27 * [fetchmail](http://fetchmail.berlios.de/)
29 See the [[initial_tagging]] page for more info on intial tagging of messages.
31 * <span id="print_filenames">**Print only filenames of a search (python bindings)**</span>
33 Notmuch includes python bindings to the notmuch shared
34 library. Extensive API documentation [is
35 available](http://notmuchmail.readthedocs.org/).
37 The bindings are very simple to use. As an example, given you have
38 the python bindings installed (or simply set your PYTHONPATH
39 environment variable to point to the .../bindings/python directory),
40 this script will print the filenames of a matching search:
43 >>> db = notmuch.Database()
44 >>> query = db.create_query('tag:inbox AND NOT tag:killed')
45 >>> list(query.search_messages()) # doctest:+ELLIPSIS
48 * <span id="sync_maildir_flags">**Sync notmuch tags and maildir flags**</span>
50 notmuch **since version 0.5** syncs maildir flags and respective
51 tags in both directions. This part applies only to notmuch prior to
54 Some IMAP users rely on maildir flags that convey the status "seen",
55 "replied", "trashed", in order to synchronize the status of their
56 mail across mail clients (a [maildir
57 flag](http://cr.yp.to/proto/maildir.html) is simply a defined part
58 of their filename). Notmuch will by default happily ignore those
59 flags and will never modify them either, as there is no built-in
60 support for synchronizing your notmuch tags with your imap maildir
61 flags (seen, replied, trashed, etc). However there are currently 2
62 ways in which you can achieve synchronization.
64 [notmuchsync](http://spaetz.github.com/notmuchsync/) is a utility
65 (based on the cnotmuch python bindings) that allows synchronization
66 in either direction, as well as pruning of deleted files.
68 The second solution allows for fast maildir flag to notmuch tag
69 synchronization (and only in that direction) requires patching the
70 notmuch source code. The patch has been posted in this mail
71 *id:1267450136-31749-1-git-send-email-Sebastian@SSpaeth.de* and can
72 be viewed as a [source diff in this git
73 repository](http://github.com/spaetz/notmuch-all-feature/commit/df3b087cefb85e9d16fd17540e348bcb854dd7ee).
75 * <span id="print_filenames">**Using notmuch with Mutt**</span>
77 Notmuch is a great mail indexing tool that can also be used *in conjunction*
78 with existing Mail User Agents (MUA) instead of replacing them. The advantage
79 of such mixed solutions is that users can benefit from notmuch features (such
80 as full-text search and thread reconstruction) without *having to* change
83 A popular geek MUA is [the Mutt e-mail client](http://www.mutt.org);
84 integrating notmuch with Mutt is fairly straightforward. An
85 [**how to use Notmuch with Mutt**](http://upsilon.cc/~zack/blog/posts/2011/01/how_to_use_Notmuch_with_Mutt/)
86 has been written by Stefano Zacchiroli, together with some glue code. Check
88 [howto](http://upsilon.cc/~zack/blog/posts/2011/01/how_to_use_Notmuch_with_Mutt/)
91 <small>(Note by the howto author: I've linked the howto from this wiki rather
92 than splicing it in, in order to avoid duplication of information. If you
93 think it would be better to have it here, feel free to copy the text

98 * <span id="reapply_auto">**Automatically retagging the database (e.g., when upgrading versions)**</span>
100 Certain versions of notmuch include new automatic tags (for example, between
101 0.3 and 0.10, automatic tagging of signed and encrypted messages was added).
102 However, for users running with databases created in older versions of
103 notmuch, these tags are missing in pre-existing messages and need to be
104 added. One way to do this is as follows:
106 $ notmuch dump ~/out.nm
107 $ mv ~/Mail/.notmuch ~/.notmuch.bak
109 $ notmuch tag -inbox -unread '*'
110 $ notmuch restore --accumulate ~/out.nm
112 At this point, one should run a sanity check on the tags, and if everything
113 has merged correctly, the ~/.notmuch.bak directory is expendable, as is
116 * <span id="nbox">**Dealing with mbox and other formats**</span>
118 notmuch by itself is unable to handle non-maildir mail archives. One tool
119 to solve this is called mb2md. Assuming an mbox in ~/test.mbox and ones
120 mail archives to be in ~/Mail, an invocation would look like
122 $ mb2md -s ~/test.mbox -d ~/Mail/mynewmaildirname
124 Note that specifying the paths for -s and -d is necessary. This will create
125 a new maildir in ~/Mail/mynewmaildirname from the mbox at ~/test.mbox.
127 Often the formats are more convoluted, however. Many lists provide an
128 almost-but-not-quite-mbox format that mailman produces, as can be seen, for
129 example, [here](http://lists.xapian.org/pipermail/xapian-devel/). These
130 files can be converted with some degree of success to mbox using the script
132 [here](http://www.hermann-uwe.de/blog/converting-mailman-gzipd-text-archive-files-to-proper-mbox-files),
133 and from mbox to maildir as above.
135 However, many of these lists also have a gmane version, which, where it
136 exists, achieves far better results than dealing with the messy mailman
137 output. Using the instructions from [Gmane's
138 site](http://gmane.org/export.php), we can download an mbox file, which we
139 can then convert to maildir using mb2md or other utility.
