58 Chapter 4 WebMail

Users log in to 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 the mail service administration guide.

When users log in to WebMail, their passwords are sent over the Internet in clear text

(not encrypted) unless the website is configured to use SSL. For instructions on

configuring SSL, see “Enabling SSL” on page 50.

WebMail users can consult the user manual for SquirrelMail at www.squirrelmail.org/

wiki/UserManual.

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 59.

WebMail Protocols

WebMail uses standard email protocols and requires your mail server to support them.

These protocols are:

• Internet Message Access Protocol (IMAP) for retrieving incoming mail

• Simple Mail Transfer Protocol (SMTP) for exchanging mail with other mail servers

(sending outgoing mail and receiving incoming mail)

Note: The SquirrelMail configuration script allows setting the IMAP server type. The

setting “macosx = Mac OS X Mailserver” refers to the older Apple MailServer in

Mac OS X Server version 10.2. In Mac OS X version 10.3 and version 10.4, the correct

setting (and the one set by default) is “cyrus = Cyrus IMAP Server.”

WebMail does not support retrieving incoming mail via Post Office Protocol (POP). Even

if your mail server supports POP, WebMail does not.
