Web Service 359
Users access your Web site’s WebMail page by appending /WebMail to the URL of your site.
For example,
http://mysite.example.com/WebMail
Users log into WebMail with the name and password they use for logging in to regular mail
service. WebMail does not provide its own authentication. For more information on mail
service users, see “Supporting Mail Users” on page 405 in Chapter 9, “Mail Service.”
When users log in to WebMail, their passwords are sent over the Internet in clear text (not
encrypted) unless the Web site is configured to use SSL. For instructions on configuring SSL,
see “Enabling SSL for Web Service” on page 346.
WebMail users can consult the user manual for SquirrelMail at the following Web page:

WebMail and Your Mail Server
WebMail relies on your mail server to provide the actual mail service. WebMail merely
provides access to the mail service through a Web browser. WebMail cannot provide mail
service independent of a mail server.
WebMail uses the mail service of your Mac OS X Server by default. You can designate a
different mail server if you are comfortable using the Terminal application and UNIX
command-line tools. For instructions, see “Configuring WebMail” on page 360.
WebMail Protocols
WebMail uses standard email protocols and requires your mail server to support them:
m Internet Message Access Protocol (IMAP) for retrieving incoming mail
m Simple Mail Transfer Protocol (SMTP) for exchanging mail with other mail servers
(sending outgoing mail and receiving incoming mail)
WebMail does not support retrieving incoming mail via Post Office Protocol (POP). Even if
your mail server supports POP, WebMail does not.
Enabling WebMail
You can enable WebMail for the Web site (or sites) hosted by your Web service. Changes take
effect when you restart Web service.
1 Make sure your mail service is started and configured to provide IMAP and SMTP service.
The mail service of Mac OS X Server provides IMAP and SMTP service by default. For details
on mail service configuration, see Chapter 9, “Mail Service.”
2 Make sure IMAP mail service is enabled in the user accounts of the users you want to have
WebMail access.
