Chapter 1 Mail Service Setup 15

Enabling Secure Mail Transport With SSL

The mail service requires some configuration to provide SSL connections automatically.

The basic steps are as follows:

• Generate a Certificate Signing Request (CSR) and create a keychain.

• Use the CSR to obtain an SSL certificate from an issuing authority.

For more information on enabling SSL from the web technologies administration guide

and the Open Directory administration guide.

If you already have generated a certificate in a previous version of Mac OS X Server, it

won’t be compatible with the current mail service.

For detailed instructions for allowing or requiring SSL transport, see the following

sections:

• “Configuring SSL Transport for POP Connections” on page 20

• “Configuring SSL Transport for IMAP Connections” on page 21

• “Configuring SSL Transport for SMTP Connections” on page 23

Before You Begin

Before setting up mail service for the first time:

• Decide whether to use POP, IMAP, or both for incoming mail.

• If your server will provide mail service over the Internet, you need a registered

domain name. You also need to determine whether your ISP will create your MX

records or you will create them in your own DNS service.

• Identify the people who will use your mail service but don’t already have user

accounts in a directory domain accessible to your mail service. You must create user

accounts for these mail users.

• Determine mail storage requirements, and ensure you have enough disk space for

your anticipated mail volume.

• Determine your authentication and transport security needs.

How User Account Settings Affect Mail Service

In addition to setting up mail service as described in this chapter, you can also

configure some mail settings individually for everyone who has a user account on your

server. Each user account has settings that do the following:

• Enable or disable mail service for the user account, or forward incoming mail for the

account to another email address.

• Specify the server that provides mail service for the user account.

• Set a quota on the amount of disk space for storing the user account’s mail on the

server.

• Specify the protocol for the user account’s incoming mail: POP, IMAP, or both.
