aerc-notmuch - notmuch configuration for aerc(1)

aerc supports using the notmuch email system as a backend, for fast indexing and searching.

For this to be enabled, aerc needs to be build with notmuch support.
Refer to the installation instructions for details.

Notmuch accounts currently are not supported with the :new-account command and must be added manually.

In accounts.conf (see aerc-config(5)), the following notmuch-specific options are available:



The source indicates the path to the directory containing your notmuch database (usually a .notmuch folder).

The path portion of the URL following notmuch:// must be either an absolute path prefixed by / or a path relative to your home directory prefixed with ~. For example:

source = notmuch:///home/me/mail

source = notmuch://~/mail


Path to a file containing a mapping from display name to notmuch query in the form of NAME=QUERY.
Multiple entries can be specified, one per line.
Lines starting with '#' are ignored and serve as comments.

e.g. inbox=tag:inbox and not tag:archived

Default: none


Comma separated list of tags which will be excluded from query results, unless explicitly mentioned in the query.
This can for example be useful if you use an archive or spam tag.

Default: none

Notmuch shows slightly different behaviour than for example imap.
Some commands are simply unsupported because they have no proper counterpart in notmuch, like :delete and :archive.
Others are slightly different in semantics and mentioned below:

cf <notmuch query>

The change folder command allows for arbitrary notmuch queries and should usually be preferred over :filter as it will be much faster if you use the notmuch database to do the filtering
