Chapter 8. Configuring the Cyrus Server
Now that the none-too-exciting work of building Cyrus IMAP is over, let’s get down to business and configure it.
IMAP Configuration File and Directory
The Cyrus IMAP server has a single configuration file:
/etc/imapd.conf. No messing about with the source code or the
Makefile is necessary. Once you’ve used the appropriate options to make a build of Cyrus that’s appropriate for your site, any configuration is done simply by editing
The Server Configuration File: imapd.conf
First, let’s create the
/etc/imapd.conf file, which holds all the defining configuration parameters for imapd. Each line of
imapd.conf contains an option and a value for the option, separated by a colon:
Blank lines and lines beginning with
# are treated as comments and are ignored. Boolean options take the values
on to turn the option on, and
off to turn the option off.
For the time being, it’s best to minimize the number of entries in this file to make debugging your installation easier. The barebones IMAP configuration file must contain at least the following entries:
configdirectory: /var/imap partition-default: /var/spool/imap admins: cyrus johndoe2
See Table 8-1 for the purpose of each of the three options.
