8 Best Mail Transfer Agents (MTA’s) for Linux

Posted on by Paolo Redaelli

In this article, we have looked a slight understanding of how MTA’s (Mail Transfer Agents) work and a list of the best and most used MTA’s on Linux systems.

Source: 8 Best Mail Transfer Agents (MTA’s) for Linux

I knew the “infamous” SendMail, and also Postfix, Exim, Qmail.

OpenSMTPD and Postal are new to me. But I don’t understand why they mixed servers with Mutt and Alpine that are clients….

Unknown pearls

Posted on by Paolo Redaelli

I already knew many of the software listed in 40 Must-Have Free Open Source Applications for 2024 but of course, one never stop learning, so I discovered some interesting pearls unknown to me:

  • Jaspersoft Studio is a report designer program that allows you to create simple and sophisticated reports as well with charts, tabs, tables (and everything you can expect to see in a world-class report) and export them to a wide variety of formats (with PDF perhaps being the most common).
  • Bleachbit not only will recover disk space by deleting temporary or otherwise unnecessary files but will also improve Firefox’s performance and securely destroy unnecessary files to prevent recovery.
  • Open Computer and Software Inventory Next Generation, or OCS Inventory NG for short, is a lightweight web application that can help network and system administrators to keep track of 1) all the devices connected to the network, and 2) machine configuration and software installed in them.
  • GLPI is a multilingual, free IT asset management software that not only provides the tools to build up a database with an inventory of your network devices but also includes a job tracking system with mail notifications.
  • If you own a small or medium business you will undoubtedly need a Point Of Sale program. As such, uniCenta oPOS may be a lifesaver for you. It uses a MySQL / MariaDB database for data storage, and thus a single database can be used with multiple active terminals at the same time.
  • LAN Messenger is a multilingual (a language pack is needed) and cross-platform (works in Linux, Windows, and Mac) IM program for communication over a LAN. It provides file transfers, message logging, and event notifications – all without the need to set up a server!
  • Both available as Enterprise (paid) and Community editions, LogicalDOC is an award-winning, web-based Document Management System (DMS). As such, it aims to provide a high-quality method for sharing business documents and records in a low-cost and secure way.
  • PDF Mix Tool, a simple and lightweight program that makes it possible to perform common PDF editing operations, such as file merging and page rotation. Well, actually PDF Arranger offers most of the same functionalities with a better user interface

Then one sour point: Visual Studio Code is a NOT Free Software. Just avoid it!

Terminals renaissance

Posted on by Paolo Redaelli

How far have we gone since DEC VT100! All those terminal emulator have evolved a lot from the humble Xterm… In recent years we have seen several “modern” terminal emulators. A first wave focused on being shiny and polished or just stylish such as cool-retro-term (which is shamefully not listed on the list on Wikipedia). Recently we are seeing interesting, fresh and new approach to terminal emulation, which is possible in my opinion thanks to the sheer power of recent machines. Let’s see some of them:

Wave: A Modern New Linux Terminal that You’ll Love if You Hate Command Line

Rio Terminal

  • Fast and Fast: The Rio has fast performance, leveraging the latest technologies including Rust and advanced rendering architectures.
  • 24-bit true color: Regular terminals are limited to just 256 colors, the Rio supports “true color,” which means it can display up to 16 million colors.
  • Images in Terminal: The Rio can display images within the terminal using iTerm2 and kitty image protocols.
  • Cross-platform:
  • Rio is a cross-platform app that runs on Windows, macOS, Linux, and FreeBSD.

WaveTerm: An open-source, cross-platform terminal for seamless workflows

Render anything inline. Save sessions and history. Powered by open web standards.

alacritty.org

Alacritty is a modern terminal emulator that comes with sensible defaults, but allows for extensive configuration. By integrating with other applications, rather than reimplementing their functionality, it manages to provide a flexible set of features with high performance. The supported platforms currently consist of BSD, Linux, macOS and Windows.
