You should delete the 'User-Agent' header from outgoing email
I have come to think that this is a bad idea and that you should configure your mail submission server to strip User-Agent (and probably also X-Mailer). First off, leaving this header in leaks information about your users to various people. With the way that the Internet has evolved, hiding this information is now the right answer, much like hiding user IPs turned out to be the right call. If you need to know client and device usage information for your own purposes, log the header value before you delete it (but understand that not all clients may add it in the first place).
(This information leaks not just to the people who your users send email to, but also to the people who operate the receiving email servers. These days that often means Google and Microsoft.)

The Squeal of Data
Today in Tedium: My favorite sound in computing is one that I haven’t actually had to use on a computer in nearly 20 years. The modem was a connection to a world outside of my own, and to get that connection required hearing the sounds of a loud, abrasive handshake that could easily be mistaken for Lou Reed’s Metal Machine Music. I’d like to compare it to another kind of sound for a little bit—the noise of a “straight key” used for a telegraph. Both technologies, despite more than a century in age difference, seemingly turned data into sound, then into electrical pulses, and back into sound again. It’s no wonder, then, that you can actually trace the roots of the modem back to the telegraph, and later the teletype machine. Data and wires, simply put, go way back. And it’s not the only example of the telegraph’s quiet influence on modern computing. Today’s Tedium draws a line between the modern computer and the pulses that inspired it. — Ernie @ Tedium

How To Use a Proxy Server in Linux Mint 20 (For Beginners)
Roughly four out of every five internet users encountered internet censorship in 2022.
But not every user hits a virtual wall when attempting to access a website or online service for the same reason. Besides content regulations, geopolitics and company policies also influence website restrictions.

Proxy Servers that you can combine with Linux or Unix
Proxies, in their various forms, serve as vital intermediaries between your network and the websites or services you access. When it comes to choosing the right proxy for your needs, considerations such as privacy, anonymity, speed and connection stability come into play. If you’re using Linux or Unix systems, you have the advantage of flexibility and compatibility with a wide range of proxy options. For privacy-conscious users or those engaged in data collection, proxies like residential proxies can provide a more authentic and anonymous browsing experience.
On the other hand, if your focus is on optimizing speed and connection performance, dedicated datacenter proxies are often the preferred choice. Linux and Unix users can easily configure and manage these proxies, leveraging the operating system’s robust networking capabilities. By understanding the unique advantages that Linux or Unix can offer in terms of proxy compatibility, you can choose the most suitable proxy type for your specific use case, whether it’s privacy-oriented tasks, high-speed activities like gaming or automation tasks. We look at the difference between residential and dedicated datacenter proxies, like the options Smartproxy offers.
