AERC-IMAP(5)
# NAME
aerc-imap - IMAP configuration for *aerc*(1)
# SYNOPSIS
aerc implements the IMAP protocol as specified by RFC 3501, with the following
IMAP extensions:
- IDLE (RFC 2177)
- LIST-STATUS (RFC 5819)
- X-GM-EXT-1 (Gmail)
# CONFIGURATION
Basic IMAP configuration may be done interactively with the *:new-account*
command.
In _accounts.conf_ (see *aerc-accounts*(5)), the following IMAP-specific options
are available:
*source* = _<scheme>_://_<username>_[_:<password>_]_@<hostname>_[_:<port>_]_?_[_<oauth2_params>_]
Remember that all fields must be URL encoded. The _@_ symbol, when URL
encoded, is _%40_.
Possible values of _<scheme>_ are:
_imap_
IMAP with STARTTLS
_imap+insecure_
IMAP without STARTTLS
_imaps_
IMAP with TLS/SSL
_imaps+insecure_
IMAP with TLS/SSL, skipping certificate verification
_imaps+oauthbearer_
IMAP with TLS/SSL using OAUTHBEARER Authentication
_<oauth2_params>_:
If specified and a _token_endpoint_ is provided, the configured password
is used as a refresh token to obtain an access token. If _token_endpoint_
is omitted, refresh token exchange is skipped, and the password acts
like an access token instead.
- _token_endpoint_ (optional)
- _client_id_ (optional)
- _client_secret_ (optional)
- _scope_ (optional)
Example:
imaps+oauthbearer://...?token_endpoint=https://...&client_id=
_imaps+xoauth2_
IMAP with TLS/SSL using XOAUTH2 Authentication. Parameters are
the same as OAUTHBEARER.
*source-cred-cmd* = _<command>_
Specifies the command to run to get the password for the IMAP
account. This command will be run using _sh -c command_. If a
password is specified in the *source* option, the password will
take precedence over this command.
Example:
source-cred-cmd = pass hostname/username
*connection-timeout* = _<duration_>
Maximum delay to establish a connection to the IMAP server. See
https://pkg.go.dev/time#ParseDuration.
Default: _30s_
*keepalive-period* = _<duration>_
The interval between the last data packet sent (simple ACKs are not
considered data) and the first keepalive probe. After the connection is
marked to need keepalive, this counter is not used any further. See
https://pkg.go.dev/time#ParseDuration.
By default, the system tcp socket settings are used.
*keepalive-probes* = _<int>_
The number of unacknowledged probes to send before considering the
connection dead and notifying the application layer.
By default, the system tcp socket settings are used.
If keepalive-period is specified, this option defaults to 3 probes.
This option is only supported on linux. On other platforms, it will be
ignored.
*keepalive-interval* = _<duration>_
The interval between subsequential keepalive probes, regardless of what
the connection has exchanged in the meantime. Fractional seconds are
truncated.
By default, the system tcp socket settings are used.
If *keepalive-period* is specified, this option defaults to _3s_.
This option is only supported on linux. On other platforms, it will be
ignored.
*check-mail-include* = _<folder1,folder2,folder3...>_
Specifies the comma separated list of folders to include when checking for
new mail with *:check-mail*. Names prefixed with _~_ are interpreted as regular
expressions. This setting is ignored if your IMAP server supports the
LIST-STATUS command, in which case all folders will be checked.
By default, all folders are included.
*check-mail-exclude* = _<folder1,folder2,folder3...>_
Specifies the comma separated list of folders to exclude when checking for
new mail with *:check-mail*. Names prefixed with _~_ are interpreted as regular
expressions. This setting is ignored if your IMAP server supports the
LIST-STATUS command, in which case all folders will be checked.
Note that this overrides anything from *check-mail-include*.
By default, no folders are excluded.
*cache-headers* = _true_|_false_
If set to _true_, headers will be cached. The cached headers will be stored
in _$XDG_CACHE_HOME/aerc_, which defaults to _~/.cache/aerc_.
Default: _false_
*cache-max-age* = _<duration>_
Defines the maximum age of cached files. Note: the longest unit of time
*cache-max-age* can be specified in is hours. Set to _0_ to disable cleaning
the cache
Default: _720h_ (30 days)
*idle-timeout* = _<duration>_
The length of time the client will wait for the server to send any final
update before the IDLE is closed.
Default: _10s_
*idle-debounce* = _<duration>_
Specifies the length of time from the last client command until the
idler starts.
Default: _10ms_
*use-gmail-ext* = _true_|_false_
If set to _true_, the X-GM-EXT-1 extension will be used if supported.
This only works for Gmail accounts.
Default: _false_
