Building a simple spam worker

Hi there, I am trying to build a simple spam worker which would go through an array of email domains I maintain, and if the email's domain belongs to this array, then the worker will block it, otherwise I would receive it. I have go it up to so far:

export default {
  async email(message, env, ctx) {
    const block = ["yourprofithour.com", "modernfinancialhabits.com", "oracleofomahasays.com"]
    if (block.indexOf(message.headers.get("from")) == -1) {
      await message.forward("md@outlook.com.au");
    } else {
      message.setReject("Address is blocked");
    }
  }
}


Q1/ The example has the exact email address but I want it to block at domain level. Would above work?

Q2/ Instead of having a fixed string for the message.forward can the code detect the original email address the email was sent to, and forward to that address?

Q3/ After Save and Delploy, I think I still need to set Action = Send to a Worker, and choose this spam-worker from the Destination drop down, or otherwise I don't think the spam worker is activated. Correct?

Appreciate your help.
