NAME
aerc-config - configuration file formats for aerc(1)
CONFIGURATION
There are three aerc config files: aerc.conf, binds.conf, and accounts.conf. The last one
must be kept secret, as it may include your account credentials. We look for these files
in your XDG config home plus "aerc", which defaults to ~/.config/aerc.
Examples of these config files are typically included with your installation of aerc and
are usually installed in /usr/share/aerc.
Each file uses the ini format, and consists of sections with keys and values. A line
beginning with # is considered a comment and ignored, as are empty lines. New sections
begin with [section-name] on a single line, and keys and values are separated with "=".
AERC.CONF
This file is used for configuring the general appearance and behavior of aerc.
GENERAL OPTIONS
These options are configured in the [general] section of aerc.conf.
default-save-path
Used as a default path for save operations if no other path is specified.
UI OPTIONS
These options are configured in the [ui] section of aerc.conf.
index-format
Describes the format for each row in a mailbox view. This field is compatible with
mutt's printf-like syntax.
Default: %D %-17.17n %s

stylesets-dirs
The directories where the stylesets are stored. The config takes a colon-separated
list of dirs. If this is unset or if a styleset cannot be found, the following paths
will be used as a fallback in that order:
~/.config/aerc/stylesets
~/.local/share/aerc/stylesets
/usr/local/share/aerc/stylesets
/usr/share/aerc/stylesets
Default: ""
styleset-name
The name of the styleset to be used to style the ui elements. The stylesets are stored
in the 'stylesets' directory in the config directory.
Default: default
Have a look at aerc-stylesets(7) as to how a styleset looks like.
fuzzy-folder-complete
When finding a folder with cf or move, for example, the popover will how not only the
folders /starting/ with the string input by the user, but it will show coincidences of
folders /containing/ the string in any position of their name. This is case-
independent.
threading-enabled
Enable a threaded viewing of messages, works with IMAP (when there's server support)
and NotMuch backends.
This option should only be set to true for specific accounts accordingly. See
Contextual UI Configuration below.
Default: false
Contextual UI Configuration
The UI configuration can be specialized for accounts, specific mail directories and
message subjects. The specializations are added using contextual config sections based on
the context.
The contextual UI configuration is merged to the base UiConfig in the following order:
Base UIConfig > Account Context > Folder Context > Subject Context.
[ui:account=<AccountName>]
Adds account specific configuration with the account name.
[ui:folder=<FolderName>]
Add folder specific configuration with the folder name.
[ui:folder~<Regex>]
Add folder specific configuration for folders whose names match the regular
expression.
[ui:subject~<Regex>]
Add specialized ui configuration for messages that match a given regular expression.
Example:
[ui:account=Work]
sidebar-width=...
[ui:folder=Sent]
index-format=...
[ui:folder~Archive/d+/.*]
index-format=...
[ui:subject~^[PATCH]
index-format=...
VIEWER
These options are configured in the [viewer] section of aerc.conf.
pager
Specifies the pager to use when displaying emails. Note that some filters may add ANSI
escape sequences to add color to rendered emails, so you may want to use a pager which
supports ANSI.
Default: less -R
alternatives
If an email offers several versions (multipart), you can configure which mimetype to
prefer. For example, this can be used to prefer plaintext over HTML emails.
Default: text/plain,text/html
header-layout
Defines the default headers to display when viewing a message. To display multiple
headers in the same row, separate them with a pipe, e.g. "From|To". Rows will be
hidden if none of their specified headers are present in the message.
Default: From|To,Cc|Bcc,Date,Subject
show-headers
Default setting to determine whether to show full headers or only parsed ones in
message viewer.
Default: false
always-show-mime
Whether to always show the mimetype of an email, even when it is just a single part.
Default: false
COMPOSE
These options are configured in the [compose] section of aerc.conf.
editor
Specifies the command to run the editor with. It will be shown in an embedded
terminal, though it may also launch a graphical window if the environment supports it.
Defaults to $EDITOR, or vi(1).
header-layout
Defines the default headers to display when composing a message. To display multiple
headers in the same row, separate them with a pipe, e.g. "To|From".
Default: To|From,Subject
address-book-cmd
Specifies the command to be used to tab-complete email addresses. Any occurrence of
"%s" in the address-book-cmd will be replaced with anything the user has typed after
the last comma.
The command must output the completions to standard output, one completion per line.
Each line must be tab-delimited, with an email address occurring as the first field.
Only the email address field is required. The second field, if present, will be
treated as the contact name. Additional fields are ignored.
Example:
khard email --remove-first-line --parsable '%s'
Default: none
reply-to-self
Allow to include your own address. Otherwise, if set to false, do not mail yourself
when replying (e.g., if replying to emails previously sent by yourself, address your
replies to the original To: and Cc:).
Default: true
FILTERS
Filters allow you to pipe an email body through a shell command to render certain emails
differently, e.g. highlighting them with ANSI escape codes. They are configured in the
[filters] section of aerc.conf.
The first filter which matches the email's mimetype will be used, so order them from most
to least specific.
You can also match on non-mimetypes, by prefixing with the header to match against (non-
case-sensitive) and a comma, e.g. subject,text will match a subject which contains "text".
Use header,~regex to match against a regex.
aerc ships with some default filters installed in the share directory (usually
/usr/share/aerc/filters). Note that these may have additional dependencies that aerc does
not have alone.
TRIGGERS
Triggers specify commands to execute when certain events occur.
They are configured in the [triggers] section of aerc.conf.
new-email
Executed when a new email arrives in the selected folder.
e.g. new-email=exec notify-send "New email from %n" "%s"
Default: ""
Format specifiers from index-format are expanded with respect to the new message.
TEMPLATES
Templates are used to populate the body of an email. The compose, reply and forward
commands can be called with the -T flag with the name of the template name.
aerc ships with some default templates installed in the share directory (usually
/usr/share/aerc/templates).
These options are configured in the [templates] section of aerc.conf.
template-dirs
The directory where the templates are stored. The config takes a colon-separated list
of dirs. If this is unset or if a template cannot be found, the following paths will
be used as a fallback in that order:
~/.config/aerc/templates
~/.local/share/aerc/templates
/usr/local/share/aerc/templates
/usr/share/aerc/templates
Default: ""
new-message
The default template to be used for new messages.
Default: "new_message"
quoted-reply
The default template to be used for quoted replies.
Default: "quoted_reply"
forwards
The default template to be used for forward as body.
Default: "forward_as_body"
ACCOUNTS.CONF
This file is used for configuring each mail account used for aerc. Each section is the
name of an account you want to configure, and the keys & values in that section specify
details of that account's configuration. In addition to the options documented here,
specific transports for incoming and outgoing emails may have additional configuration
parameters, documented on their respective man pages.
Note that many of these configuration options are written for you, such as source and
outgoing, when you run the account configuration wizard (:new-account).
archive
Specifies a folder to use as the destination of the :archive command.
Default: Archive
copy-to
Specifies a folder to copy sent mails to, usually "Sent".
Default: none
default
Specifies the default folder to open in the message list when aerc configures this
account.
Default: INBOX
folders
Specifies the comma separated list of folders to display in the sidebar. Names
prefixed with ~ are interpreted as regular expressions.
Default: all folders
folders-exclude
Specifies the comma separated list of folders to exclude from the sidebar. Names
prefixed with ~ are interpreted as regular expressions. Note that this overrides
anything from folders.
Default: no folders
enable-folders-sort
If true, folders are sorted, first by specified folders (see folders-sort), then
alphabetically.
Default: true
folders-sort
Specifies a comma separated list of folders to be shown at the top of the list in the
provided order. Remaining folders will be sorted alphabetically.
Default: none
from
The default value to use for the From header in new emails. This should be an RFC
5322-compatible string, such as "Your Name <you@example.org>".
Default: none
aliases
All aliases of the current account. These will be used to fill in the From: field.
Make sure that your email server accepts this value, or for example use aerc-
sendmail(5) in combination with msmtp and --read-envelope-from.
Default: none
outgoing
Specifies the transport for sending outgoing emails on this account. It should be a
connection string, and the specific meaning of each component varies depending on the
protocol in use. See each protocol's man page for more details:
• aerc-smtp(5)
outgoing-cred-cmd
Specifies an optional command that is run to get the outgoing account's password. See
each protocol's man page for more details.
Default: none
postpone
Specifies the folder to save postponed messages to.
Default: Drafts
source
Specifies the source for reading incoming emails on this account. This key is required
for all accounts. It should be a connection string, and the specific meaning of each
component varies depending on the protocol in use. See each protocol's man page for
more details:
• aerc-imap(5)
• aerc-maildir(5)
• aerc-notmuch(5)
Default: none
source-cred-cmd
Specifies an optional command that is run to get the source account's password. See
each protocol's man page for more details.
signature-file
Specifies the file to read in order to obtain the signature to be added to emails sent
from this account.
signature-cmd
Specifies the command to execute in sh in order to obtain the signature to be added to
emails sent from this account. If the command fails then signature-file is used
instead.
BINDS.CONF
This file is used for configuring keybindings used in the aerc interactive client. You may
configure different keybindings for different contexts by writing them into different
[sections] of the ini file. The available contexts are:
[messages]
keybindings for the message list
[view]
keybindings for the message viewer
[compose]
keybindings for the message composer
[compose::editor]
keybindings for the composer, when the editor is focused
[compose::review]
keybindings for the composer, when reviewing the email before it's sent
[terminal]
keybindings for terminal tabs
You may also configure account specific key bindings for each context:
[context:account=<AccountName>]
keybindings for this context and account, where <AccountName> matches the account name
you provided in accounts.conf.
Example:
[messages:account=Mailbox]
c = :cf path:mailbox/** and<space>
[compose::editor:account=Mailbox2]
...
You may also configure global keybindings by placing them at the beginning of the file,
before specifying any context-specific sections. For each key=value option specified, the
key is the keystrokes pressed (in order) to invoke this keybinding, and value specifies
keystrokes that aerc will simulate when the keybinding is invoked. Generally this is used
to execute commands, for example:
rq = :reply -q<Enter>
Pressing r, then q, will simulate typing in ":reply -q<Enter>", and execute :reply -q
accordingly. It is also possible to invoke keybindings recursively in a similar fashion.
Additionally, the following special options are available in each binding context:
$noinherit
If set to "true", global keybindings will not be effective in this context.
Default: false
$ex
This can be set to a keystroke which will bring up the command input in this context.
Default: <semicolon>
In addition to letters, special keys may be specified in <angle brackets>. The following
special keys are supported:
