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  Aerc  will  make  its  best to purge deleted/outdated information.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>.
