Uh-oh. Do Bcc: recipients all show up on everyone's screen?
Running Thunderbird 128.2.3esr under Windows 10, I just noticed something for the first time. I sent a broadcast message to myself, but included four friends under Bcc:. When I got my own copy of the email, from the address on the To: line, I see that the Bcc: list is visible, as shown in the attached image. Is this JUST on my received copy of the message, or is everyone's name 'in the clear?'
Thinking that my outgoing message might have been cached-and-used or something, I went into my Gmail Web account and looked at the message as received by Google's servers. Sure enough, the 'blind' (ostensibly hidden!) names show up there as well, so I'm assuming that the Bcc: function may not be doing its job. Either that, or the primary (To:) recipient sees the Bcc: list in the clear, and listed Bcc: recipients won't, although I don't recall Thunderbird working this way in the past. But if it does, that's okay, just that Windows Live Mail, my previous client, didn't.

is the from: an to: gmail address the same? I ask because Gmail hides the received email and pretends it is the original you send. They also remove anything in the BCC fields and replace it with "undisclosed recipients" resulting on a lot of complaints over the years on this forum about the BCC entries disappearing from the send email.
This is the first time I have ever seen someone says they see BCC names even in the sent folder.

So, Matt, do I understand you correctly, it's Gmail that sends the original back to the sender? I made the test using a couple of other email accounts that I have, and the Bcc: recipients did NOT show up in either the message or the header as received through those accounts in Thunderbird. But the one I got on the same Gmail account I sent it out on did indeed look very much like the original, in that the Bcc: recipients were there in the message and in the header. So the secret of who-all got the 'blind' message is safe, despite one's own message received appearing to tattle. Thanks for the explanation.
Oh, and yes, the Bcc: recipients are in the original outgoing message that's in the Thunderbird Sent folder. I would expect this to be the case, although I never paid attention before.
