Moritz Poldrack 94bff9130d config: add option to hide timezone in sent emails 
Some people are worried that they might leak their timezone and wish to
send their mails with the Date header in UTC. For this a new key is
added to the account sections to enforce sending in UTC instead of the
system's timezone.

aerc-config(5)
# 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.
*pgp-provider*
If set to "gpg", aerc will use system gpg binary and keystore for all
crypto operations. Otherwise, the internal openpgp implementation will
be used.
Default: internal
*unsafe-accounts-conf*
By default, the file permissions of accounts.conf must be restrictive
and only allow reading by the file owner (_0600_). Set this option to
*true* to ignore this permission check. Use this with care as it may
expose your credentials.
Default: false
## UI OPTIONS
These options are configured in the *[ui]* section of aerc.conf.

*threading-enabled*
Enable a threaded view of messages. If this is not supported by the
backend (IMAP server or notmuch), threads will be built by the client.
Default: false
*force-client-threads*
Force threads to be built client-side. Backends that don't support threading
will always build threads client side.
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=...
```
## STATUSLINE
These options are configured in the *[statusline]* section of aerc.conf.
*render-format*
Describes the format string for the statusline format.
For a minimal statusline that only shows the current account and
the connection information, use [%a] %c.
To completely mute the statusline (except for push notifications), use
%m only.
Default: [%a] %S %>%T
[- *Format specifier*
:[ *Description*
| %%
: literal %
| %a
: active account name
| %d
: active directory name
| %c
: connection state
| %m
: mute statusline and show only push notifications
| %S
: general status information (e.g. connection state, filter, search)
| %T
: general on/off information (e.g. passthrough, threading, sorting)
| %>
: does not print anything but all format specifier that follow will be right justified.
*separator*
Specifies the separator between grouped statusline elements (e.g. for
the %S and %T specifiers in *render-format*).
Default: " | "
*display-mode*
Defines the mode for displaying the status elements.
Options: text, icon
Default: text
## 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.
Authentication information from the Authentication-Results header can be
displayed by adding DKIM, SPF or DMARC. To show more information
than just the authentication result, append a plus sign (+) to the header name
(e.g. DKIM+).
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
*parse-http-links*
Parses and extracts http links when viewing a message. Links can then be
accessed with the open-link command.
Default: true
## 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.
This parameter can also be set per account in accounts.conf.
Example:
khard email --remove-first-line --parsable '%s'
Default: none
*reply-to-self*
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.
Note that said email body is converted into UTF-8 before being passed to
filters.
## 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:
```
${XDG_CONFIG_HOME:-~/.config}/aerc/templates
${XDG_DATA_HOME:-~/.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
*check-mail*
Specifies an interval to check for new mail. Mail will be checked at
startup, and every interval. IMAP accounts will check for mail in all
unselected folders, and the selected folder will continue to receive PUSH
mail notifications. Maildir/Notmuch folders must use *check-mail-cmd* in
conjunction with this option. See *aerc-maildir* and *aerc-notmuch* for
more information.
Setting this option to 0 will disable check-mail
Example: 5m
Default: 0
*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
*outgoing-cred-cmd-cache*
By default, the credentials returned by the command will be cached until
aerc is shut down. If set to false, *outgoing-cred-cmd* will be executed
every time an email is to be sent.
Default: true
*pgp-auto-sign*
If true, all outgoing emails from this account will be signed (if a signing
key is available)
Default: false
*pgp-key-id*
Specify the key id to use when signing a message. Can be either short or
long key id. If unset, aerc will look up the key by email
*pgp-opportunistic-encrypt*
If true, any outgoing email from this account will be encrypted when all
recipients (including "cc" and "bcc" field) have a public key available in
the keyring
Default: false
*postpone*
Specifies the folder to save postponed messages to.
Default: Drafts
*send-as-utc*
Converts the timestamp of the Date header to UTC.
Default: false
*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.
*trusted-authres*
Comma-separated list of trustworthy hostnames from which the
Authentication Results header will be displayed. Entries can be regular
expressions. If you want to trust any host (e.g. for debugging),
use the wildcard \*.
# 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
*[view::passthrough]*
keybindings for the viewer, when in key passthrough mode
(toggled with :toggle-key-passthrough)
*[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*.
Folder-specific bindings can be configured for message lists:
*[messages:folder=<FolderName>]*
keybindings under this section will be specific to the folder named
<FolderName>. Keybindings from a *folder* specifier will take precedence
over *account* specifiers
Example:
```
[messages:account=Mailbox]
c = :cf path:mailbox/** and<space>
[compose::editor:account=Mailbox2]
[messages:folder=Drafts]
<Enter> = :recall<Enter>
...
```
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:
[[ *Name*
