Is it based on mail undeliverable errors? Or attempts to login using IMAP or SMTP with it? Or is it exposed during the SMTP protocol?

My guess would be it has nothing to do with email itself. Maybe it's some iCloud API that accepts obfuscated emails but returns the original email in the response, or an ID which can be used to retrieve the iCloud email from another API endpoint. Could be as simple as an "add contact/friend" feature in some Apple product (like a mail client, or a file sharing service) that resolves the obfuscated email to the original iCloud account.

As someone who doesn't rely on this feature, I'd love to know now as well, but perhaps the etiquette in public would be to align ourselves with:

> we will not discuss or disclose the details of the exploits until they're fixed.

But if there's a public forum where the cat's already out of the bag, then game on. Perhaps this:

I think you should formally write to Apple and give notice of 30 days to contact you or you will reveal it.

Send it to the USA media and regulator too

I think "real email" address is underselling it, since that's commonly the apple-ID, which is the gateway to some people's whole digital existence. Not to mention the fact, you tend to use hidemyemail in particular for services you don't want any identity leaked to. The "real email" may contain your legal name already.

That's disappointing, both that the vulnerability exists in the first place, and that Apple takes over a year to not even fix it.
