Add this before return smtp.send(settings) to log all SMTP communication and post what you get in Logs:

Code:

settings.create = function()
  local sock = socket.tcp()

  return {
    settimeout = function(_, ...)
      return sock:settimeout(...)
    end,
    connect = function(_, ...)
      return sock:connect(...)
    end,
    close = function(_, ...)
      return sock:close(...)
    end,
    receive = function(_, ...)
      local res, err, partial, time = sock:receive(...)
      log('receive', res, err, partial)
      return res, err, partial, time
    end,
    send = function(_, ...)
      log('send', ...)
      return sock:send(...)
    end
  }
end
