This plugin facilitates scanning messages with Rspamd.

## Configuration

rspamd.ini

- host

  Default: localhost

  Host to connect to to query Rspamd.

- port

  Default: 11333

  Port Rspamd is listening on.

- unix_socket

  Path to a unix socket to connect to. If set, overrides host and port.

- scheme

  Default: http

  Transport for network connections (`http` or `https`). Ignored when
  `unix_socket` is set.

- path

  Default: /checkv2

  HTTP path for rspamd checks.

- add_headers

  Default: sometimes

  Possible values are:

        "always" - always add headers
        "never" - never add headers (unless provided by rspamd - see rmilter_headers)
        "sometimes" - add headers when rspamd recommends `add header` action

  Format of these headers is governed by header.\* settings

- tls.reject_unauthorized

  Default: true

  Default: undefined

  Optional HTTP Basic Auth credentials for protected rspamd endpoints.

  Default: undefined

  Optional custom auth header. `auth.value_env` reads the header value from an
  environment variable.

  Default: undefined

  Comma-separated `Flags` header value for rspamd protocol options.

- request.body_block / request.ext_urls / request.groups / request.milter /
  request.no_log / request.profile / request.skip / request.skip_process /
  request.zstd

  Default: false

  Boolean helpers that append protocol flags to `Flags`.

- request.pass_all

  Default: false

  Sends `Pass: all` to force all rspamd filters for a request.

- request.raw

  Default: false

  Sends `Raw: yes` for non-MIME/raw body scanning.

  Additional headers to pass to rspamd (for example, `MTA-Tag`).

- reject.message

  Default: Detected as spam

  Message to send when rejecting mail due to Rspamd policy recommendation.

- reject.spam

  Default: true

  If set to false, ignore recommended _reject_ action from Rspamd (except
  for authenticated users).

  If true, messages from localhost will be scanned by Rspamd.

- dkim.enabled

- soft_reject.message

  Default: Deferred by policy

  Message to send to remote server on rspamd soft rejection.

- spambar.positive

  Default: +
