Let’s be honest — no server runs without errors forever. No matter how perfectly you configure it, sooner or later something will go wrong. Maybe a file won’t be found, a script will fail, or a resource becomes unavailable. The key is not to panic, but to catch the issue as early as possible so you can fix it right away. But who really wants to keep staring at logs in the terminal all day, searching for errors manually? Wouldn’t it be much nicer if your server could just send you a message on Telegram the moment something breaks?
Let me show you how to set that up in just 15–20 minutes.
When you decide to set up your own mail server, the first thing that comes to mind is reliability. You need a tool that can handle the email traffic, won’t crash at the worst possible moment, and won’t trap you in endless complicated configurations. One such tool is Exim4.
Exim4 is not just another mail-sending program. It’s a reliable mail transfer agent (MTA) that can receive emails, route them to the right recipients, and send them further. It supports encryption, filtering, connection to external SMTP servers, direct mail reception, and custom processing according to your needs.
Why Exim? Because it’s flexible. You can tailor it for any task — whether it’s a small home server or a large mail service with thousands of users. The key is not to be afraid of the settings. And here we’ll show you how to configure it without unnecessary pain.
If you miss the good old-fashioned way of seeing what program you have open-not just an icon, but a caption-then good news: in Windows 11, you can now enable taskbar captions again. Here's how to do it.
Even the most powerful smartphone starts to run slower over time. Applications take longer to load, the interface slows down, and some games stop running altogether. Why does this happen - and are there any ways to get your device back to its former snappiness? Let's find out.
When you encounter a bug in Linux or try to explain what went wrong, the easiest thing to do is to show terminal output. Especially if you're asking for help on a forum, discussing a bug with a colleague, or sending a report to a developer. No one likes to copy kilometers of output manually, and it is a questionable pleasure to parse such sheets. In such cases, termbin - a simple and convenient tool that allows you to share output from the terminal literally in a couple of clicks - comes in handy. It creates a short link that shows the whole log at once.
Thanks to the Open-Shell program, anyone can bring back the familiar classic interface. It's quick to set up, and it works stably. And yes, the program is completely free.
