Warning: Gmail client can misrepresent bounce message content

Here’s the original-message part of an bounce message: https://i.vgy.me/0KpICY.png

Here’s the Gmail web client (Windows, Chrome) display of it:

———- Forwarded message ———-
From: Chris Jordan
To: Chris John Jordan
Cc:
Bcc:
Date: Sun, 19 Oct 2025 10:32:03 +0100
Subject: Test
Test 2

Gmail has fabricated Cc and Bcc fields!

And “Bcc: ” is in this case incorrect, given the real Bcc field has two addresses (which the bounce generator did not include, of course).
