Even Ispmail Workaround has no ide how to update Dovecot.

Do not try to upgrade your existing server using apt-get dist-upgrade. There are too many changes especially with Dovecot.

This is LandChad.net, a site dedicated to turning internet peasants into Internet Landlords by showing them how to setup websites, email servers, chat servers and everything in between. Starting a website is something that can be done in a lazy afternoon and costs pocket change. Most of the internet’s problems could be solved if more people had their own personal platforms, so the objective of this site is to guide any normal person through the process of installing a website.

The Book of Secret Knowledge is a large GitHub repository curating an invaluable collection of cheatsheets, manuals, CLI/web tools, hacks, and inspiring lists primarily aimed at System/Network administrators, DevOps engineers, and Security Researchers.

Anubis weighs the soul of your connection using a sha256 proof-of-work challenge in order to protect upstream resources from scraper bots.

This program is designed to help protect the small internet from the endless storm of requests that flood in from AI companies. Anubis is as lightweight as possible to ensure that everyone can afford to protect the communities closest to them.

Anubis is a bit of a nuclear response. This will result in your website being blocked from smaller scrapers and may inhibit “good bots” like the Internet Archive. You can configure bot policy definitions to explicitly allowlist them and we are working on a curated set of “known good” bots to allow for a compromise between discoverability and uptime.

A glimpse at AI’s alarming negative impact on sysadmins’ time and its intrusiveness

Running even a single server connected to the internet can be a challenge these days. There are many technologies involved - some are arcane (DNS), some are constantly evolving (TLS), and some look simple but are amazingly hard to get right (DNSSEC). And then, there are some which are all of the above, such as “a mail server” 1…

These technologies are the foundation of the internet, so you cannot be ignorant towards them. But it is also unreasonable to expect everyone to know everything about them 2. Hence, every now and then, it makes sense to turn to some tools to help you out.

If this sounds familiar to you, you have probably heard of the big names: the (formerly) Qualys SSL Analyzer, the ubiquitous MXToolbox, or maybe services like Hardenize. These services do provide value, and they are free-as-in-beer to use. I am not linking to them, but I would also never condemn their usage. However, I do want to draw some attention to existing open source alternatives.

Internet.nl helps you to check whether your internet is up to date. Do your website, email and internet connection use modern and reliable Internet Standards? And if they don’t, what can you do about it? Who is behind Internet.nl?

The test tool Internet.nl is an initiative of the Dutch Internet Standards Platform. The aim of the platform is to jointly increase the use of modern Internet standards to make the Internet more accessible, safer and more reliable for everyone. The platform is a collaboration between parties from the Internet community and the Dutch government. The following parties are currently participating in the platform:
