Chapter 6. Handling Locally Generated Mail

Mail comes from two conceptual places: inside your system and outside it. In this chapter, we look at mail that originates inside your system, mail generated locally on the host where qmail is running. We also take a first look at mail injected by MUAs on computers running on the same LAN, and mail injected by "roaming" local users elsewhere on the Net, which we address in detail in the next chapter.
