This document describes how to install a Postfix mail server that is based on virtual users and domains, i.e. users and domains that are in a MySQL database. I'll also demonstrate the installation and configuration of Courier (Courier-POP3, Courier-IMAP), so that Courier can authenticate against the same MySQL database Postfix uses. The resulting Postfix server is capable of SMTP-AUTH and TLS and quota. Passwords are stored in encrypted form in the database. In addition to that, this tutorial covers the installation of Amavisd, SpamAssassin and ClamAV so that emails will be scanned for spam and viruses. I will also show how to install SquirrelMail as a webmail interface so that users can read and send emails and change their passwords.

For the past year my netbook of choice has been the Samsung NC10 as while it shipped with stock Intel Atom hardware like other netbooks such as the Dell Mini 9 and earlier ASUS Eee PCs, the Samsung was built very well and possessed a rather large and well laid out keyboard for only being a 10.6" mobile computer. Catching my attention recently though has been the ASUS Eee PC 1201N netbook, which packs quite a bit of horsepower with offering the Intel Atom 330 dual-core CPU and NVIDIA's ION platform to provide compelling graphics capabilities. The Eee PC 1201N also ships with 2GB of RAM, a 250GB hard drive, and a 1366 x 768 display that measures in at 12.1". Oh yeah, ASUS claims a several hour battery life for this $500 USD netbook too along with a full-size keyboard. As was alluded to last week, I ended up purchasing the ASUS Eee PC 1201N as soon as it was made available on the Internet. This is now the initial Phoronix rundown on the 1201N for how it works with Ubuntu Linux, including many benchmarks.

One of the major benefits to having a wireless network is when a display device has the facility to utilise the connection, therefore removing any copying of content from one drive to another when the devices are several feet away…

Redeye, wrong exposure, blemishes, and other defects can afflict your holiday photos. But despair not, for GIMP can fix them. And here's a little secret: it's easy. Akkana Peck shows how.

Intel's reworked Atom platform enhances netbooks and Internet devices with integrated graphics and memory controller.

Thunderbolts and Revelations. Metaphorically, they can be perceived as the same thing. Of course, "Thunderbolt" carries a bit more drama and impact...an idea or fact that comes upon you so swiftly and powerfully, it is perceived as profound or moving.

I got a phone call yesterday from a recruiter wondering if I would be interested in a Linux administrator position. The first question she asked was did I have any experience with Oracle RAC and I could hear her eyes glaze over as I answered her with a brief description of what I have done with RAC. After shaking herself back to life, she asked if I had any experience with Unbreakable Linux.

Wine-Reviews and Bordeaux T-shirts now available at freewear.org Well, first, our T-shirts are free as in speech but not as in beer, I mean, you can wear them orwards, backwards and sideways, and we will not sue you for sharing them with your friends. We think different, and give preference to quality over amount of colours

DigiKam main developer Gilles Caulier has released version 1.0 of the KDE photo management software just in time for Christmas 2009.

Intel announced its new "Pineview" Atom processors, touting a 20 percent improvement in average power consumption and a smaller package size. The N450, aimed at netbooks, is a single-core Atom processor clocked at 1.66GHz, while the D410 and D510, single- and dual-core respectively, target entry-level desktop PCs, the company says.

After a wave of operating system releases, it's easy to become somewhat bored with the software side of computing. Windows 7 is here and looking like the "real" Vista for many; Mac OS X 10.6, meanwhile, adds spit-shine to Leopard and gives its engine a good tuning too. In the Linux camp, distributions are taking regular steps forward in usability. But it's all become rather routine; a case of incremental improvement rather than revolution. So where's all the real fun happening? Where are the radical new ideas, the Wild West code commits and the geekery and hackery that really drive innovation?

One of the difficulties open source software faces is in implementing support — where it is even possible to do so — for the wide variety of codecs, formats, and other proprietary technologies that users have come to rely on. One such technology is Microsoft's Silverlight framework, which until early this year, was a no-go for Linux users. That changed in January, when the first version of the Moonlight project — a collaboration between the Novell-sponsored Mono project and Microsoft, begun in 2007 — was released, providing Linux users with Open Source Silverlight support. Also included, provided that Moonlight has been obtained via Novell and meets certain other conditions, is a license to Microsoft's free but closed-source Media Pack, containing codecs needed to decode audio and video streams.

With the end of the next kernel version's main development phase, the most important new features of Linux 2.6.33 have been determined: DRBD, Nouveau, support of the Trim ATA command and a bandwidth controller for block devices. The developers have also improved the Radeon drivers and the support of Intel Wi-Fi chips. New stable kernels also fix a vulnerability in the code of Ext4, but will shortly be superseded by even more current versions.

Digikam is a powerful and complete photo management tool for KDE. Among its many features is the ability to run batch processes, thanks to the Kipi plugin set, which is also used in other KDE software like Gwenview. With a few simple clicks, users can manipulate multiple photos simultaneously, without having to remember long command line strings or taking countless hours to edit each file.

It has been roughly a month since Tech Data launched Open Tech — an open source channel partner initiative. Why is the big distributor interested in the open source market? And how is Open Tech performing so far? I caught up with Tech Data VP Stacy Nethercoat for answers. Here's the interview.

There are probably more than 250,000 Free and Open Source Software tools available to solve problems. How can an administrator support the largest subset possible? Debian provides the most cost effective way.

What is it that really holding Linux & FOSS software back from absolute domination? In a sentence "go read the source code". The thing that's meant to be its strength is its greatest flaw. But its fixable, fix this one, stand well back, watch the World Change!

If your new year's resolution is to kick the Microsoft habit, here are some Linux versions you might want to look at.

Jolicloud aims to be a solid netbook OS that "just works." But then, don't they all? Paul Ferrill takes it for a spin and learns if it lives up to the hype.

A first shot at creating a port of the Qt toolkit to Google's Native Client (NaCL) environment allows Qt applications to run as applets within a browser. The port is not yet complete, but it already offers mouse and keyboard support, rudimentary support for the QtGUI and QtCore libraries and several more complex widgets. The biggest problem with the current port though is that the event handling in NaCL is polling based which makes applications spin using 100% of the CPU; the developers descibe this as "not quite our preferred style".
