Hello, I just wanted to share my story regarding having a domain with Njalla using ProtonMail/SimpleLogin’s services.

TLDR (full story below): You may not be able to send emails from your domain with ProtonMail/SimpleLogin if your domain is registered with Njalla (or any other “privacy-friendly” domain registrar).

Full-story:

I had a domain with Njalla (njal.la) for a couple of years, and at the same time, I was using this domain with ProtonMail (to send emails from my domain) and SimpleLogin (catch-all aliases with my domain). I never had any issues during the last few years until recently:

• A few months ago, beginning of 2025, I suddenly wasn’t able to send emails from my domains/aliases: They were rejected (“Undelivered Mail Returned to Sender”) because I was listed on Spamhaus (a service which lists domain reputation, check.spamhaus.org). I contacted Proton’s support, and they advised me to reach out Spamhaus directly to resolve this issue. I was able to request a delisting of my domain “automatically” (through a form), and a few days later, my domain had been “automatically” delisted and I was thus able to send emails again.
• A month ago, my domain has suddenly been re-listed on spamhaus, again. This time, I wasn’t prompted with the automatic delisting form like the first time. I had to contact through a form Spamhaus and I had to write a small text requesting to be delisted and explaining to them how I was not using my domain for spamming/scaming/bulk email sending/etc… This time, spamhaus refused to delist my domain because my domain was considered as an Internet neighbourhood with “poor reputation” that has shared (or inevitably will share) its negative reputation. (…) The domain is not eligible for removal while being associated with this neighbourhood. We recommend moving your domain to a hosting network with good reputation.. I was talking with Njalla’s support and ProtonMail’s support at the same time, and they basically both told me that there is nothing they could do. I was basically forced to transfer my domain to a new domain hoster provider. And not any other domain hoster, but one with a “good” reputation (when I asked if transfering to 1984 (https://1984.hosting/), a privacy-friendly domain provider, Spamhaus discouraged me to do so.

To sum it up, by having your domain with any privacy-friendly service (like Njalla, 1984, …), there is a chance that your domain will be listed on Spamhaus, preventing you from using your domain with ProtonMail/SimpleLogin.

I find it ironic from Proton, as they even encourage using Njalla/1984 in one of their blog article: https://proton.me/blog/professional-domain-and-email. At the end, I’m a bit pissed by Spamhaus’s behaviour and also ProtonMail for using such services.

Here are screenshots of my discussions with ProtonMail, Njalla and Spamhaus support if anyone is interested enough in reading the whole discussions: https://postimg.cc/gallery/phgVK4M

Just wanted to share my story to help other people know about this issue and the issues they might encounter with ProtonMail based on their DNS provider choice.
