Managing Mail Service

This sections provides basic steps to set up Mail service on Mac OS X Server and explains the tools you use to manage Mail service.

Before You Begin

Before setting up Mail service for the first time:

ÂÂ If you are upgrading from a previous version of Mac OS X Server, you might need to take special steps to upgrade Mail service. See “Viewing Mailing List Archives” on page 53.

ÂÂ Decide whether to use POP, IMAP, or both for accessing mail.

ÂÂ If your server will provide Mail service over the Internet, obtain a registered domain name.

ÂÂ Determine whether your ISP will create your MX records or whether you’ll create them using your own DNS service. See “Configuring DNS for Mail Service” on page 21.

ÂÂ Identify the people who will use Mail service but who don’t have user accounts

in a directory domain accessible to Mail service. Then create user accounts for these mail users.

ÂÂ Determine your authentication and transport security needs. See “Understanding SMTP Authentication” on page 26.
