Mail Service 381
Requiring or Allowing Kerberos Authentication
You can choose to require, allow, or disallow the Kerberos authentication method for all
SMTP, IMAP, and POP mail service.
Before enabling Kerberos authentication for mail service, you must integrate Mac OS X with a
Kerberos server. For instructions, see “Integrating Mac OS X With a Kerberos Server” on
page 199 in Chapter 3, “Users and Groups.”
To enable Kerberos authentication of mail service:
1 In Server Settings, click the Internet tab.
2 Click Mail Service and choose Configure Mail Service.
3 Click the General tab.
4 Choose a method from the Authentication pop-up menu and click Save.
Choose Standard if you want mail service to use the authentication methods that are set by
clicking POP Options, IMAP Options, and SMTP Options in the Protocols tab.
Choose Kerberos if you want mail service to require Kerberos authentication for POP, IMAP,
and SMTP. In this case, users’ mail client software must support Kerberos.
Choose Any Method if you want to allow but not require the use of Kerberos authentication. A
mail client that does not support Kerberos can use the standard authentication method instead.
Adding or Removing Local Names for the Mail Server
Your mail service has a list of all the domain names for which it is responsible. You should
add any names that are likely to appear after @ in the addresses of mail directed to your
server. For example, the list might contain variations of the spelling of your domain name or
company name. Your mail settings apply to all domain names in this list.
To add or remove local names for the mail server:
1 In Server Settings, click the Internet tab.
2 Click Mail Service and choose Configure Mail Service.
3 Click Add and type the domain name of a virtual mail host for which you want your server to
be responsible.
To remove an item from the list, select it and click Remove.
4 Click Save.
Note: If you’ve set up MX records, you don’t need to add anything to this list. Your mail
service will add names as it discovers them in the course of its daily operation.
