What you say makes a ton of sense.? I didn't notice the option of the source code.
How does GIO check/verify the sender?? I have no idea how/method, but I'd guess there's ways for a mal sender to spoof the "From" address (like spoofed robo calls "from" phone numbers) but I'd suspect email servers check and dump messages (never make their way out the door) that don't authenticate it's from an actual email user?
