This chapter has covered the set up of virtual domains and users within the qmail architecture, both how to use qmail's formidable virtualization features to achieve separate domain namespaces, and also how to further virtualize even the qmail queue itself to use different configuration settings. The next chapter will push the envelope of what the qmail architecture can do much further than virtualization. Filters around each architectural component, akin to the qmail-queue
wrapper presented in this chapter, allow the administrator to radically change the system's behavior.

Overview of this book
This book starts with setting up a qmail server and takes you through virtualization, filtering, and other advanced features like hosting multiple domains, mailing lists, and SSL Encryption. Finally, it discusses the log files and how to make qmail work faster.
Qmail is a secure, reliable, efficient, simple message transfer agent. It is designed for typical Internet-connected UNIX hosts. Qmail is the second most common SMTP server on the Internet, and has by far the fastest growth of any SMTP server. Qmail's straight-paper-path philosophy guarantees that a message, once accepted into the system, will never be lost. Qmail also optionally supports maildir, a new, super-reliable user mailbox format.
