Telekom is a bunch of strange folks. I lately was not able to send mails, from my private mail servrr to my fathers telekom mail. After investigation I found out my server got blocked. After a decade of working. I mailed them, and they told me to register my mailserver with them. I shall tell them what mails I will send from there and about what content. I couldn’t believe my eyes. Sure, thats how mail was supposed t…

That policy of theirs has existed for a long time now. It's a really odd one at that. They also don't enforce DMARC, nor do DKIM. It's stuck nearly four decades in the past.

Microsoft has a similar policy on their consumer domains though. If they have not received mail from you for a month or so you are insta blocked. It's infuriating for personal mail server owners.

Been there, done that. After a bit of back and forth, Telekom basically recommended that I go and use one of the big SMTP servers and stop bothering them. While I hated myself for doing it, I eventually switched to Gmail for peace of mind.

Does Fastmail have any clout in Europe? I've been a customer for the better part of a decade (with my own domain name) and I've never had a mail delivery issue.

I was going to suggest Fastmail too. I don't know about Europe in particular but have been a very happy Fastmail customer for several years, running mail for 2 small corporations plus personal, zero problems ever.

I own a FTTH connection to Telekom since 2018, as the only provider in my street, allowed to install an internet connection (only glass fiber). Since then, I have always used my own device and I maintain a GitHub Snippet in how to connect OpenWRT modem (and by extension, any other modem that supports pppoe), rather than their Huawei SpeedPort crap or the more expensive Fritz Box). Link to Gist : https://gist.github.c…

Sorry to say but how you are framing things is simply not true anymore. You are not required to buy their "Glasfaser Modem 2" you can buy any ONT Modem. You are not required to use any of their equipment, they give you the data to connect via PPPOE directly. I bought a house with FTTH in 2023 and never used any Telekom hardware. Nobody forces you to use the peer DNS. The telekom DNS isn't complying to https://cuii.in…

> Nobody forces you to use the peer DNS.

For practical purposes there's the problem (at least a few years ago?) though that Akamai in particular uses DNS to steer you to the correct portion of its CDN and the default IPs returned by independent DNS resolvers tended to have relatively abysmal peering with the Telekom network that was getting completely overloaded at peak times.

Unfortunately "use everywhere except for Akamai CDN, for which use the Telekom DNS" isn't something that consumer routers support, so you'd have to start running your own custom DNS resolver to work around that problem…

I think this is standard. It applies to domains as well. I experienced government services blocks as well -- they send me an email, yet block my reply. I complain every time and rarely does anyone care, the support person does not escalate, so my email remains blocked, sometimes I'm told system is working as configured, completely ignoring that I am a real person and system is hostile towards me.

We call it the email mafia. To send emails we need to pay for a mail service. Or get ads of course Gmail is part of the ring. Like most things it start with good intentions, to fight spam. As if it even worked, I guess we would get far more without they will say.

It's one of the downsides of decentralized networks. Trust is built or pay-your-way-into'd.

ISP “choice” is mostly a meme, yeah. But depending on local rules, you can sometimes route around the monopoly: trench your own last-mile (at least on private land), do a neighborhood co-op, connect buildings, etc. It’s sometimes expensive and you’ll hit permits/right-of-way bureaucracy, but it’s totally doable if you’ve got a few (rich) friends or a business willing to back it. “the conduit is full” is often just BS…

I think Germany has something equivalent to local loop unbundling, but obviously, DT still provides shitty loops because they are shitty at all aspects of their business.

Local loop unbundling is only mandatory for large ISPs. There are many regional or otherwise smaller carriers that have a local monopoly. Fortunately, they tend to be OK (with some exceptions like Deutsche Glasfaser, they are basically bankrupt and behaving quite erratically).

And the USA changed policy where Europeans became enemies ("we won't give you arms to defend against Russian invaders! Greenland will be occupied by our military soon!"). It's a bad si…

The best solution here would probably be the EU launching its own internet constellation. China and the US both have them. How is this any different than the issues surrounding GPS?

A better solution is guaranteed broadband internet for all people living in Germany. With heavy fines if ISPs can't deliver that.

I'm not sure you read the OP's comment in full. They are talking about inbound traffic from the Internet. It's certainly a lot more common a case to self-host an MX than running an open DNS resolver or authorative name server.

You may be surprised to learn that there are many types of botnets out there, and many use DNS queries for the C&C. Although the GP wrote "53/tcp" that is a weird situation, because most (not all) DNS is over UDP. One day I suddenly found my DNS resolver logs were very active with veritable gibberish. And it seems that my router had been pwned and joined some sort of nefarious botnet. I only found this out because I…

That's none of the business of my ISP to care about. If a botnet abuses my connection to send excessive traffic, that's going to be limited by the bandwidth limit I'm paying for.

Restricting ports also doesn't mitigate it, as a port scanner can easily find out I'm running this or that vulnerable server software on a non-standard port.

It's none of the ISP's business to restrict the ports I should be using.

Is there a government requirement to be reachable by its citizens? That would seem to violate it.

I mean, yes? But that's by sending a letter, or a fax. Email is not part of this...

Telekom is well known for the crappy service - but they have a de facto monopoly. For example, when it rains, the line goes down where I live. Solution: I got my Starlink. 3x speed. No crappy service. Weather independent. And surprinsingly cheaper ( 40 euros vs 45 ) . [ as much as I do not like Musk & co, this is a real useful thing he build for the mankind - internet everywere from sattelite ]

Except that with Telekom they answer to the German courts which might eventually force them to stop doing this but with Starlink you're at the mercy of some dudes halfway across the globe. If/when Starlink reaches the enshittification phase, there will be very little in the way.

German courts are expected to be much more hostile towards German citizens than any foreign powers or individuals.
