26 Chapter 1 Mail Service Setup
Step 9: Start mail service
Before starting mail service, make sure the server computer shows the correct day,
time, time zone, and daylight-saving settings in the Date & Time pane of System
Preferences. Mail service uses this information to timestamp each message. An
incorrect timestamp may cause other mail servers to handle a message incorrectly.
Also, make sure you’ve enabled one or more of the mail service protocols (SMTP, POP,
or IMAP) in the Settings pane.
Once you’ve verified this information, you can start mail service. If you selected the
Server Assistant option to have mail service started automatically, stop mail service
now, then start it again for your changes to take effect. For detailed instructions, see
“Starting and Stopping Mail Service” on page 57.
Step 10: Set up each user’s mail client software
After you set up mail service on your server, mail users must configure their mail client
software for your mail service. For details about the facts that users need when
configuring their mail client software, see “Supporting Mail Users” on page 37.
Configuring Incoming Mail Service
Configuring incoming mail service is configuring mail to be retrieved by users and
email client applications. It involves three basic steps:
• Choose and enable the type of access (POP, IMAP, or both).
• Choose a method for authentication of the email client.
• Choose a policy for secure transport of email data over SSL.
The following section contains information on how to accomplish these three steps.
Enabling POP Access
POP is used for receiving mail. The POP mail service stores incoming POP mail until
users have their computers connect to the mail service and download their waiting
mail. After a user’s computer downloads POP mail, the mail is stored only on the user’s
computer. An advantage of using POP is that your server doesn’t need to store mail
that users have downloaded.
POP isn’t the best choice for users who access mail from more than one computer, such
as a home computer, an office computer, and a laptop while on the road because once
messages are accessed by one computer, they are deleted from the server.
