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…

Does anyone self host email anymore successfully? I'm honestly asking. I would like to but it seems like a full time job trying to keep it running. Are there halfway solutions where maybe you own the service and domain and it runs somewhere trusted?

I have been running my mail server for about 20 years now, using three different domains.

I have switched servers regularly, mostly between OVH/online.net/Hetzner since they are the three big cheap European hosts. I have also used various server software, now happily running OpenSMTPd.

I have had a few problems with Microsoft in the past but contacting them (what made me care enough was marrying someone with an @hotmail email address) eventually fixed delivery for good. No notable delivery problems otherwise. I also run my company's mail server, it works fine too (with a much larger volume and different usage patterns), also running out of OVH servers.

What I recommend for people who don't want to do sysadmin is buying a domain at OVH to use the free email service offered with it. It's cheap and works, and it's easy to switch to another registrar or provider if needed.

> This also describes transit and describes getting internet service at home. Well no. Transit means that you use another AS (usually by a larger ISP) to get connectivity to a certain AS. And as for your internet service at home, unless you announce an AS, you are not peering with anyone.

Peering has everything to do with the physical interconnect and nothing to do with the ID numbers used to describe that interconnect, IMO.

Then we are just talking about two different things.

On ISP level, routing tables are built via BGP. BGP needs Autonomous Systems (AS) as organization unit to work. If you are not an AS you are never a peer as you are not on equal footing.

As a rule of thumb, if your edge router has a default route set, we are very likely talking about different scales.

>I don't think Germans realize just how much DTAG is holding the experience back for end users The ones not on HN probably just notice that their internet is getting slow after 5 p.m Trust me, I know how much they suck and I still had to enter a 2-year contract just to get fiber optics in my house.

They tried to install it to our home too, but our landlord just didn't do anything to help them to open doors and now we've been soon waiting two years for the connection.

The more I read about DTAG the happier I feel like using our cable connection which, upstream excluded, works quite well.

We're about to buy our apartment in Berlin and that changes things. I hope we have soonpre choice on the fiber operator.

fwiw t-online.de hasn't been owned by Deutsche Telekom since 2015

but the fun thing about them is, they allow you to impersonate any mail address you want with their smtp server. Aka, when you are a customer of them you get a @t-online.de address and login data for their smtp server. You can just login into that server and set the From: Header to anything, they don't check.

Isn't that fairly common? You could then put in some other address, but you could do the same thing by setting up your own mail server, and in the former case you're not even really anonymous because the headers are going to show it was sent through their mail server and their mail server's logs will show which account was used to send the message.

The email sent from your own separate server will fail basic dmarc/SPF/dkim validation the email sent by their own servers likely will appear legitimate

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.

Nope, but there are various good and cheap e-mail providers in EU, such as Soverin, Posteo, Mailbox, Migadu, Tuta, ...

You have the right to router freedom even with FTTH. And fortunately, with DTAG FTTH, you can also book 1und1 with good peering (:

router freedom yes, but the Telekom Black Box that takes as input the Fiber cable is still a real "black box" that needs to be installed

Here in NL I've been able to replace router (Zyxel in my case) and ONT (Huawei in my case) with one SFP+ (went with some South-Korean one). Only had to register the serial of my SFP+.

ISPs are the worst. Currently I use Telekom's 5G for my home internet connection in Hungary as Telekom is the only company who has a cable in my street, but they refused to sell me wired internet due to the hole they use to take their underground cable up to the houses being already over capacity (it turns out this "hole" serves like the entire street with cables being run across everyone's attic...). I previously us…

I think this is also relevant, after finding out Telekom, in Hungary, has the worst routes possible for some game servers:
