The following post will show you how to set-up SSL encrypted connection to our mailserver installation.
At the end of this article you will end-up using IMAP/POP3 over SSL (IMAPs/POP3s) SMTP over SSL (SMTPs) and Roundcube Webmail over SSL (HTTPS)
In this article we will show you how to install Silex via composer on Debian Wheezy VPS with PHP-FPM and Nginx . Silex is a PHP micro-framework based on the Symfony2 Components and Pimple.

Currently, SilverStripe requires PHP >= 5.3+ with MySQL, GD graphics library, tidy, curl and zlib extensions enabled, Apache Web Server >= 1.3.19 compiled with mod_rewrite module and ‘AllowOverride All’ set, and MySQL >= 5.0 installed on your Linux virtual server.
Ruby is an open source, object-oriented scripting language, best known for its use in the Ruby on Rails framework. The amount of Ruby code being written suggests it’s genuinely popular and will be around for quite some time.
This is a quick tutorial on installing Ruby 2.0 and RubyGems 2.1.11 on Ubuntu 13.10 from source. You can download, compile and install Ruby from source code on a Linux VPS with Ubuntu 13.10 OS in less than 5 minutes using the following steps:
Update the Ubuntu package lists from the repositories to get information on the newest versions of packages and their dependencies, then install Ruby dependencies using the following commands:
The following article is about how to install and set up the Roundcube webmail interface on a CentOS VPS.
It is actually part 2 of our mailserver with virtual users and domains using Postfix and Dovecot on a CentOS 6 VPS series.
Roundcube is a web-based IMAP email client written in PHP. Roundcube’s most prominent feature is the pervasive use of Ajax technology to present a more fluid and responsive user interface than one of the traditional webmail clients. It provides the full functionality you expect from an email client, including MIME support, address book, folder manipulation, message searching, spell checking, etc.
Today we will guide you through the installation process of WordPress Multisite on your Centos VPS. The WordPress Multisite option became available with WordPress 3.0. This feature allows you – the website administrator – to create multiple websites without the need of installing separate WordPress instances, creating separate home directories or separate databases. Or, you can allow other users to create their own websites on your WordPress installation.
The following article will show you how to install and run simple POP3/IMAP/SMTP mail server in your CentOS VPS using virtual users and domains with Postfix and Dovecot
What is Postfix? It is a drop in replacement for the old and mature Sendmail. Postfix also attempts to be very fast, easy to administer, and secure.
What is Dovecot? It is an open source IMAP and POP3 server for *NIX-like systems, written primarily with security in mind.
In one of our previous articles we explained how one can setup and configure a simple but powerful mail server with Postfix, Dovecot, SASL and virtual users in a Debian Squeeze VPS.
In the following article we’re going to implement SpamAssassin into the mail server setup so that it can be used to identify and tag spam email messages.
