aerc-imap - Man Page

aerc implements the IMAP protocol as specified by RFC 3501, with the following IMAP extensions:

• IDLE (RFC 2177)

IMAP configuration may be done interactively with the :new-account command.

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

source

imap[s][+insecure|+oauthbearer|+xoauth2]://username[:password]@hostname[:port]?[:oauth2_params]

Remember that all fields must be URL encoded. The "@" symbol, when URL encoded, is %40.

The meaning of the scheme component is:

imap://:

IMAP with STARTTLS

imap+insecure://:

IMAP without STARTTLS

imaps:

IMAP with TLS/SSL

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

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:

pass hostname/username

connection-timeout

Maximum delay to establish a connection to the IMAP server. See https://pkg.go.dev/time#ParseDuration.

Default: 30s

keepalive-period

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

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

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

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.

Default: all folders

check-mail-exclude

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. Note that this overrides anything from check-mail-include.

Default: no folders

cache-headers

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

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

The length of time the client will wait for the server to send any final update before the IDLE is closed.

Default: 10ms

idle-debounce

Specifies the length of time from the last client command until the idler starts.

Default: 10ms
