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)

CONFIGURATION

       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+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: 10ms

       idle-debounce = <duration>
           Specifies the length of time from the last client command until the idler starts.

           Default: 10ms
