Compare against a set of values using boolean logic in automations scripting.

• automation
• output

• start:
    set:
      message:
        subject: Receipt for your recent order
        to: customer@example.com
        from: shop@example.com
    return:
      pass@bool:
        {{
          not (
            message.to starts with 'noreply@'
            or message.from starts with 'spammer@'
          ) and (
            'receipt' in message.subject|lower
            or 'kassenzettel' in message.subject|lower
          )
        }}

• __return:
    pass: true

In this case we use the |lower filter since in is case-sensitive.
