NAME

       aerc-jmap - JMAP configuration for aerc(1)

SYNOPSIS

       aerc implements the JMAP protocol as specified by RFCs 8620 and 8621.

CONFIGURATION

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

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

       source = <scheme>://[<username>][:<password>@]<hostname>[:<port>]/<path>
           Remember that all fields must be URL encoded. The @ symbol, when URL encoded, is %40.

           <hostname>[:<port>]/<path> is the HTTPS JMAP session resource as specified in RFC 8620
           section 2 without the leading https:// scheme.

           Possible values of <scheme> are:

           jmap
               JMAP over HTTPS using Basic authentication.

           jmap+oauthbearer
               JMAP over HTTPS using OAUTHBEARER authentication

               The username is ignored and may be left empty. If specifying the password, make
               sure to prefix it with : to make it explicit that the username is empty. Or set
               the username to any random value. E.g.:

                   source = jmap+oauthbearer://:s3cr3t@example.com/jmap/session
                   source = jmap+oauthbearer://me:s3cr3t@example.com/jmap/session

           Your source credentials must have the urn:ietf:params:jmap:mail capability.

       source-cred-cmd = <command>
           Specifies the command to run to get the password for the JMAP 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

       outgoing = jmap://
           The JMAP connection can also be used to send emails. No need to repeat the URL nor any
           credentials. Just the URL scheme will be enough.

           Your source credentials must have the urn:ietf:params:jmap:submission capability.

       cache-state = true|false
           Cache all email state (mailboxes, email headers, mailbox contents, email flags, etc.)
           on disk in a levelDB database located in folder ~/.cache/aerc/<account>/state.

           The cached data should remain small, in the order of a few megabytes, even for very
           large email stores. Aerc will make its best to purge deleted/outdated information. It
           is safe to delete that folder when aerc is not running and it will be recreated from
           scratch on next startup.

           Default: false

       cache-blobs = true|false
           Cache all downloaded email bodies and attachments on disk as individual files in
           ~/.cache/aerc/<account>/blobs/<xx>/<blob_id> (where <xx> is a subfolder named after
           the last two characters of <blob_id>).

           Aerc will not purge the cached blobs automatically. Even when their related emails are
           destroyed permanently from the server. If required, you may want to run some periodic
           cleanup based on file creation date in a crontab, e.g.:

               @daily find ~/.cache/aerc/foo/blobs -type f -mtime +30 -delete

           Default: false

       use-labels = true|false
           If set to true, mailboxes with the archive role (usually Archive) will be hidden from
           the directory list and replaced by an all-mail virtual folder. The name of that folder
           can be configured via the all-mail setting.

           :archive flat may still be used to effectively "tag" messages with the hidden Archive
           mailbox so that they appear in the all-mail virtual folder. When the all-mail virtual
           folder is selected, :archive flat should not be used and will have no effect. The
           messages will be grayed out but will never be refreshed until aerc is restarted.

           Also, this enables support for the :modify-labels (alias :tag) command.

           Default: false

       all-mail = <name>
           Name of the virtual folder that replaces the role=archive mailbox when use-labels =
           true.

           Default: All mail

       server-ping = <duration>
           Interval the server should ping the client at when monitoring for email changes. The
           server may choose to ignore this value. By default, no ping will be requested from the
           server.

           See https://pkg.go.dev/time#ParseDuration.

NOTES

       JMAP messages can be seen as "labels" or "tags". Every message must belong to one or more
       mailboxes (folders in aerc). Each mailbox has a "role" as described in
       https://www.iana.org/assignments/imap-mailbox-name-attributes/.

       When deleting messages that belong only to the selected mailbox, aerc will attempt to
       "move" these messages to a mailbox with the trash role. If it cannot find such mailbox or
       if the selected mailbox is the trash mailbox, it will effectively destroy the messages
       from the server.

       :delete removes messages from the selected mailbox and effectively does the same thing
       than :tag -<selected_folder>.

       :cp <foo> is an alias for :tag <foo> or :tag +<foo>.

       :mv <foo> is a compound of :delete and :mv and can be seen as an alias of :tag
       -<selected_folder> +<foo>.

       :archive flat is an alias for :tag -<selected_folder> +<archive>.
