It is common these days for a single system to host many domains, for example uniswa.com and mtn.com or acme .com may run on a single host machine, but behave as if they were on three different hosts. A system usually has a canonical domain, it has its usual or local domain name, and additional domains are configured as virtual domains. The purpose behind this work is to create a mail server solution based on Postfix that is based on virtual users and domains, i..e. users and domains that are in a MySQL database. The goal is to have completely virtual users and domains. [email protected] != [email protected]. This means creating a separate name spaces for reach domain. It will also demonstrate the installation and configuration of Courier-Imap (IMAP/POP3), so it can authenticate against the same MySQL database Postfix uses. The resulting postfix server is capable of quota which is not built into Postfix by default; the project will demonstrate how to patch postfix appropriately. Passwords are stored in encrypted form in the database. The work also covers the installation of Mail Scanner, SpamAssassin and ClamAv so that emails will be scanned for spams and viruses. The administration of MySQL database can be done through a web based tool Postfixadmin or can be done manually in the MySQL shell. Postfixadmin is a web based management tool created for Postfix that handles Postfix style virtual domains and users that are stored in MySQL. The squirrelmail web based email client is installed, in order to check emails from anywhere in world via internet. All installations were done in Fedora 5 Linux machine.

Computer security is an ongoing process, a relentless contest between system administrators and intruders. A good administrator needs to stay one step ahead of any adversaries, which often involves a continuing process of education. If you're grounded in the basics of security, however, you won't necessarily want a complete treatise on the subject each time you pick up a book. Sometimes you want to get straight to the point. That's exactly what the new Linux Security Cookbook does. Rather than provide a total security solution for Linux computers, the authors present a series of easy-to-follow recipes--short, focused pieces of code that administrators can use to improve security and perform common tasks securely.The Linux Security Cookbook includes real solutions to a wide range of targeted problems, such as sending encrypted email within Emacs, restricting access to network services at particular times of day, firewalling a webserver, preventing IP spoofing, setting up key-based SSH authentication, and much more. With over 150 ready-to-use scripts and configuration files, this unique book helps administrators secure their systems without having to look up specific syntax. The book begins with recipes devised to establish a secure system, then moves on to secure day-to-day practices, and concludes with techniques to help your system stay secure.Some of the "recipes" you'll find in this book are: Controlling access to your system from firewalls down to individual services, using iptables, ipchains, xinetd, inetd, and more Monitoring your network with tcpdump, dsniff, netstat, and other tools Protecting network connections with Secure Shell (SSH) and stunnel Safeguarding email sessions with Secure Sockets Layer (SSL) Encrypting files and email messages with GnuPG Probing your own security with password crackers, nmap, and handy scripts This cookbook's proven techniques are derived from hard-won experience. Whether you're responsible for security on a home Linux system or for a large corporation, or somewhere in between, you'll find valuable, to-the-point, practical recipes for dealing with everyday security issues. This book is a system saver.
