The same privacy preserving features of Tutanota enjoyed by privacy conscious individuals, make it ideal for fraudsters. We experience a large number of fraudulent ecommerce orders using Tutanota email domains. I'm not shocked to think that this could be an example of an algorithm gone awry based on the signals it received.

I’m sure there are the same or more number of fraudulent cases coming from gmail accounts but they don’t block that one

As a proportion of total email volume for each service?

Interestingly, ThreeIE doesn't block them. And I'm fairly happy with them (>1Gbit/s on 5G still blows my mind), except for when I'm travelling to London and have to roam on 3 UK (I agree it sucks)

Similar experience in my town. I got a strong 5-bar signal but their backhaul must be running on 56k modems.

It is not the job of an ISP to decide what is fraudulent and what is not. They should be a dumb pipe between services and people.

That is not really true, ISPs are relied on by non-technical customers who have neither the personal chops nor a 24/7 technical assistant to help them.

Whether ISPs succeed in any way is an entirely different ballgame, but this is absolutely the job of the ISP, especially in their role of email provider. Its ability to properly discriminate and aggressively block or plonk messages isvery much one of the reasons people like gmail.

Fraudulent ecommerce orders are the only time I've seen tutanota addresses in the wild.

I have two colleagues who regularly send me emails from that domain. For the first , I assumed it was her own domain. When I saw messages from a second person I assumed they might both work for the same company. Now I figured it's an ISP. I checked it out and it looks like a good, legit service for people who don't want creeps and advertisers grubbing through their messages. Three UK have no place blocking traffic from legitimate users and must identify problematic use on a per case basis.

Modern legal systems usually limit criminal liability to individuals [1]. Companies engaging in acts of collective punishment (That goes for you too Cloudflare) should at least try to raise their ethical standards to those expected by International Law.

The question is one of ratio, and false positives versus false negatives.

If 90% of tutanota-orginated emails are fraudulent, tutanota is an excellent fraud indicator, even though it will block legitimate emails.

If 10% of gmail-originated emails are fraudulent, gmail is a terrible fraud indicator, even though it will let fraudulent emails pass through, possibly more than the count of fraudulent emails coming from tutanota.

Slightly off topic, but I was with Three UK for a while. Reception was universally terrible, and trying to use mobile data was a joke. This was in a small urban centre... called London. Would never, ever touch them again. Back on topic, it seems that they are not using Bluecoat/Symantec Site review (which I suspect other providers do), which has the domain categorised correctly: https://sitereview.bluecoat.com/#/look…

Had a similar experience and everyone I know has nothing but bad things to say about Three UK. It doesn't surprise me that it's the least popular network out of the 4 main mobile operators.

Yes similar, truly awful.

Often had to manually switch to 3G for any utility.

Also made the mistake of switching to Smarty their budget brand. Even worse (of course)
