That only works for internal communications. Once it leaves Google's servers, you lose all control. I don't know the specifics here, but the only ways to guarantee that an email server somewhere isn't caching your emails (and I don't trust Google to not cache them either) is to either encrypt them (GPG) or require hitting your server to read the email (potentially what Google is doing), and that doesn't prevent the user from copying it (but at least you can know _who _ copied it or let it be copied).

I don't know how external access works, so maybe they're doing more than they say they are, but I don't trust my coworkers, I shouldn't trust Google either. Client-side encryption is the only acceptable solution IMO.

Pretty much anything that can be consumed (read, viewed, listened to) by a person can be recorded and retransmitted in some form. This has always been true to a certain degree of course. With everyone carrying around a recording device almost everywhere, it's even truer today.

Sneaking a photo of a screen used to at least require a certain premeditation that was spy movie stuff. Today, it's casually pulling a smartphone out of a pocket.

If anyone can see or hear somewhere, barring the seeing or hearing being confined to a secure environment it can be easily and casually recorded.

I think this is only for internal communications. They were talking about this feature being “enabled by your GSuite domain administrator.” Presumably it only works for email sent between members of the affected domain (though I’m not sure why they’d fail to mention that.)

No. It does, definitely, work with external recipients.

How? If you send an email with this on to [e-mail] and I download the message to my IMAP client how does google magically reach out and delete it from my hard drive? Is the email HTML only that only displays the text when the user is online and that text is fetched from the Google server? Let us say it is and I view the email, how does Google stop me from cutting and pasting that email using my thunderbird, et.al. IMAP client?

You view the message on a Google server through a browser. The message body is never actually sent to the recipient's address.

"When someone sends a confidential mode message, Gmail removes the message body and any attachments from the recipient's copy of the message. These are replaced with a link to the content. Gmail clients make the linked content appear as if it's part of the message. Third-party mail clients display a link in place of the content."

Thank you for explaining. Also I guess I will be able to write an auto reply message that say “Sorry, I refused to received messages of this nature.”

What happens if domains have conflicting policies set?

Does that mean I then can't use a native mail client?
