Kopi will now forward mail to any Kopi address in the CC or BCC email fields. If your Kopi address (or especially, if multiple of your Kopi addresses) is in multiple fields - you might get multiple emails.
Why multiple emails?
Kopi sends a separate email to each separate Kopi address that it processes an email for. This is to protect your real address from being sent to anyone else on the CC list. Consider the case where multiple different people who use Kopi are recipients of an email.
