This is likely the spam filter scanning over the Links it finds in the E-Mail not actually something spitting the mail content into log4j (and I mean honestly, why would you even do that?)

That should be quite easy to check, by changing the URI scheme and rerunning the experiment.

How would that work with e2e encryption? What spam filter system would even follow ldap links?

Proton is not e2e for mails coming from outside Proton, if they aren't GPG encrypted. And in that case they apply very standard spam filters to your mail.

Unlikely, spammers tend to get creative to bypass spam filters, it would probably scan anything that looks like a URL or Domain just to see if the IP behind it is sus.

That’s the point. You’ll still get a hit. If it’s the RCE you won’t. Just went through this with an email security provider, would get 3-4 pings with log4j payloads, 2-3 with inert ones.

I assumed that the OP was sending from proton, to proton but looking at the screenshot again I guess that's not clear.

They have already being known to log emails when enforced by the Swiss authorities: https://techcrunch.com/2021/09/06/protonmail-logged-ip-addre... https://protonmail.com/blog/transparency-report/ —— In case you trust Swiss companies blindly: https://en.wikipedia.org/wiki/Crypto_AG https://www.thebureauinvestigates.com/stories/2021-12-06/swi...

This is always posted like some 'gotcha', despite it being right there in the transparency report.

In case you trust any company blindly: any company that wants to keep playing the money game will follow the laws forced upon them by the government they are beholden to.

Protonmail also responded in this thread with a message stating that this is in fact their spam filter.

You're free to experiment, though the ProtonMail team has already responded upthread that this is in fact their SpamFilter.

It looks like the old "Swiss secrecy" has been just marketing smoke...(see Crypto AG). I doubt any centralised entity(regardless of the country where it's hosted) can be trusted with your data. Cryptography is the only way to have some kind of assurance.

What would be useful would be for a Swiss attorney to explain the substantive and procedural law of the topic, and how the Swiss courts typically approach the issues.
