Notification using RSPAMD

sheri207

What I am trying to do is to send notifications using RSPAMD.

I Created a Lua script (notify_backend.lua) to send a webhook when Rspamd detects a new email.

/opt/mailcow-dockerized/data/conf/rspamd/custom/notify_backend.lua

local rspamd_http = require "rspamd_http"
local rspamd_logger = require "rspamd_logger"
local ucl = require "ucl"

local function notify_backend(task)
  -- Only process incoming mail
  if task:get_user() == nil then
    return
  end

  -- Get email details
  local from = task:get_from()
  local recipients = task:get_recipients()
  local subject = task:get_header('Subject')
  local message_id = task:get_header('Message-ID')
  
  -- Skip if no valid recipient or Message-ID
  if not recipients or not message_id then
    return
  end
  
  -- For each recipient, send notification
  for _, rcpt in ipairs(recipients) do
    local rcpt_email = rcpt['addr']
    
    -- Format data for API call
    local request_data = {
      recipient = rcpt_email,
      from = from and from[1] and from[1]['addr'] or "unknown@example.com",
      subject = subject or "(No subject)",
      message_id = message_id
    }
    
    -- Convert to JSON
    local json_data = ucl.to_format(request_data, 'json')
    
    -- Send HTTP request to your Laravel backend
    rspamd_http.request({
      url = 'https://staging-api.hostpepper.com/api/imap-notify',
      body = json_data,
      headers = {
        ['Content-Type'] = 'application/json'
       --  ['X-Api-Key'] = 'YOUR_SECRET_API_KEY'
      },
      callback = function(http_err, code, body, headers)
        rspamd_logger.infox(task, 'Sent notification for %s: %s', rcpt_email, code)
      end
    })
  end
end

-- Register the function to run on messages that passed spam checks
rspamd_config:register_symbol({
  name = 'NOTIFY_BACKEND',
  type = 'normal',
  callback = notify_backend,
  priority = 10
})

Enabled the script by/opt/mailcow-dockerized/data/conf/rspamd/local.d/custom_notifcations.conf

.include(try=true; priority=1) "${CONFDIR}/custom/notify_backend.lua"

My mounting on container is like this

     volumes:
        - ./data/hooks/rspamd:/hooks:Z
        - ./data/conf/rspamd/custom/:/etc/rspamd/custom:z
        - ./data/conf/rspamd/override.d/:/etc/rspamd/override.d:Z
        - ./data/conf/rspamd/local.d/:/etc/rspamd/local.d:Z
        - ./data/conf/rspamd/plugins.d/:/etc/rspamd/plugins.d:Z
        - ./data/conf/rspamd/lua/:/etc/rspamd/lua/:ro,Z
        - ./data/conf/rspamd/rspamd.conf.local:/etc/rspamd/rspamd.conf.local:Z
        - ./data/conf/rspamd/rspamd.conf.override:/etc/rspamd/rspamd.conf.override:Z
        - rspamd-vol-1:/var/lib/rspamd

Doing all this thing, still my script is not triggered whenever a new email is received. What should I do now
