NOTMUCH-CONFIG(1)

NAME

       notmuch-config - access notmuch configuration file

SYNOPSIS

       notmuch config get <section>.<item>

       notmuch config set <section>.<item> [value ...]

       notmuch config list

DESCRIPTION

The config command can be used to get or set settings in the notmuch
configuration file and corresponding database.

Items marked [STORED IN DATABASE] are only in the database. They
should not be placed in the configuration file, and should be accessed
programmatically as described in the SYNOPSIS above.

get The value of the specified configuration item is printed to std‐
out. If the item has multiple values (it is a list), each value
is separated by a newline character.

set The specified configuration item is set to the given value. To
specify a multiple-value item (a list), provide each value as a
separate command-line argument.

If no values are provided, the specified configuration item will
be removed from the configuration file.

list Every configuration item is printed to stdout, each on a sepa‐
rate line of the form:

*section*.\ *item*\ =\ *value*

No additional whitespace surrounds the dot or equals sign char‐
acters. In a multiple-value item (a list), the values are sepa‐
rated by semicolon characters.

The available configuration items are described below.

database.path
The top-level directory where your mail currently exists and to
where mail will be delivered in the future. Files should be
individual email messages. Notmuch will store its database
within a sub-directory of the path configured here named .not-
much.

Default: $MAILDIR variable if set, otherwise $HOME/mail.

user.name
Your full name.

Default: $NAME variable if set, otherwise read from /etc/passwd.

user.primary_email
Your primary email address.

Default: $EMAIL variable if set, otherwise constructed from the
username and hostname of the current machine.

user.other_email
A list of other email addresses at which you receive email.

Default: not set.

new.tags
A list of tags that will be added to all messages incorporated
by notmuch new.

Default: unread;inbox.

new.ignore
A list to specify files and directories that will not be
searched for messages by notmuch new. Each entry in the list is
either:

A file or a directory name, without path, that will be ignored,
regardless of the location in the mail store directory hierar‐
chy.

Or:

A regular expression delimited with // that will be matched
against the path of the file or directory relative to the data‐
base path. Matching files and directories will be ignored. The
beginning and end of string must be explicitly anchored. For
example, /.*/foo$/ would match "bar/foo" and "bar/baz/foo", but
not "foo" or "bar/foobar".

Default: empty list.

search.exclude_tags
A list of tags that will be excluded from search results by
default. Using an excluded tag in a query will override that
exclusion.

Default: empty list. Note that notmuch-setup(1) puts
deleted;spam here when creating new configuration file.

maildir.synchronize_flags
If true, then the following maildir flags (in message filenames)
will be synchronized with the corresponding notmuch tags:

┌─────┬────────────────────────────┐
│Flag │ Tag │
├─────┼────────────────────────────┤
│D │ draft │
├─────┼────────────────────────────┤
│F │ flagged │
├─────┼────────────────────────────┤
│P │ passed │
├─────┼────────────────────────────┤
│R │ replied │
├─────┼────────────────────────────┤
│S │ unread (added when 'S' │
│ │ flag is not present) │
└─────┴────────────────────────────┘

The notmuch new command will notice flag changes in filenames
and update tags, while the notmuch tag and notmuch restore com‐
mands will notice tag changes and update flags in filenames.

If there have been any changes in the maildir (new messages
added, old ones removed or renamed, maildir flags changed,
etc.), it is advisable to run notmuch new before notmuch tag or
notmuch restore commands to ensure the tag changes are properly
synchronized to the maildir flags, as the commands expect the
database and maildir to be in sync.

Default: true.

crypto.gpg_path
Name (or full path) of gpg binary to use in verification and
decryption of PGP/MIME messages. NOTE: This configuration item
is deprecated, and will be ignored if notmuch is built against
GMime 3.0 or later.

Default: gpg.

index.decrypt [STORED IN DATABASE]
Policy for decrypting encrypted messages during indexing. Must
be one of: false, auto, nostash, or true.

When indexing an encrypted e-mail message, if this variable is
set to true, notmuch will try to decrypt the message and index
the cleartext, stashing a copy of any discovered session keys
for the message. If auto, it will try to index the cleartext if
a stashed session key is already known for the message (e.g.
from a previous copy), but will not try to access your secret
keys. Use false to avoid decrypting even when a stashed session
key is already present.

nostash is the same as true except that it will not stash
newly-discovered session keys in the database.

From the command line (i.e. during notmuch-new(1), not‐
much-insert(1), or notmuch-reindex(1)), the user can override
the database's stored decryption policy with the --decrypt=
option.

Here is a table that summarizes the functionality of each of
these policies:

┌──────────────┬───────┬──────┬─────────┬──────┐
│ │ false │ auto │ nostash │ true │
├──────────────┼───────┼──────┼─────────┼──────┤
│Index cleart‐ │ │ X │ X │ X │
│ext using │ │ │ │ │
│stashed ses‐ │ │ │ │ │
│sion keys │ │ │ │ │
├──────────────┼───────┼──────┼─────────┼──────┤
│Index cleart‐ │ │ │ X │ X │
│ext using │ │ │ │ │
│secret keys │ │ │ │ │
├──────────────┼───────┼──────┼─────────┼──────┤
│Stash session │ │ │ │ X │
│keys
├──────────────┼───────┼──────┼─────────┼──────┤
│Delete
│stashed ses‐ │ │ │ │ │
│sion keys on │ │ │ │ │
│reindex │ │ │ │ │
└──────────────┴───────┴──────┴─────────┴──────┘

Stashed session keys are kept in the database as properties
associated with the message. See session-key in notmuch-proper‐
ties(7) for more details about how they can be useful.

Be aware that the notmuch index is likely sufficient (and a
stashed session key is certainly sufficient) to reconstruct the
cleartext of the message itself, so please ensure that the not‐
much message index is adequately protected. DO NOT USE
index.decrypt=true or index.decrypt=nostash without considering
the security of your index.

Default: auto.

index.header.<prefix> [STORED IN DATABASE]
Define the query prefix <prefix>, based on a mail header. For
example index.header.List=List-Id will add a probabilistic pre‐
fix List: that searches the List-Id field. User defined pre‐
fixes must not start with 'a'...'z'; in particular adding a pre‐
fix with same name as a predefined prefix is not supported. See
notmuch-search-terms(7) for a list of existing prefixes, and an
explanation of probabilistic prefixes.

built_with.<name>
Compile time feature <name>. Current possibilities include "com‐
pact" (see notmuch-compact(1)) and "field_processor" (see not‐
much-search-terms(7)).

query.<name> [STORED IN DATABASE]
Expansion for named query called <name>. See not‐
much-search-terms(7) for more information about named queries.

ENVIRONMENT

       The following environment variables can be used to control the behavior
       of notmuch.

       NOTMUCH_CONFIG
              Specifies  the  location of the notmuch configuration file. Not‐
              much will use ${HOME}/.notmuch-config if this  variable  is  not
              set.
