Microsoft® Exchange Server 2007: Implementation and Administration

Chapter 8. Accepting E-Mail and Generating E-Mail Addresses

When I initially started working with Exchange 2007, one thing that I had a bit of a hard time getting my head wrapped around was the concept of accepting e-mail into an Exchange 2007 organization. I think this is because Exchange 2000/2003 made it more difficult than it really needed to be. In Exchange 2000/2003, you created a recipient policy that performed a couple of different functions.

In this chapter, I will review how you define the SMTP domains for which you will accept SMTP mail and how to generate SMTP addresses for your users. The process is a bit different than it was in Exchange 2000/2003, and once you get over that difference, actually understanding how to do it is much easier. Exchange 2000/2003 combined the allowable SMTP domains and the rules for generating the SMTP addresses into a single function, but in Exchange 2007, the functions have been separated.

This chapter includes the following topics:

• Creating and managing accepted domains

• Generating e-mail addresses for users

• Defining global limits
