Managing IMAP

Installing Cyrus

Installing the Cyrus server is literally as easy as 1-2-3. Configuring the server is quite a bit more complicated, but we’ll address that in Chapter 8, Configuring the Cyrus Server . First, download and unpack the distribution. Second, decide what build-time configuration options you’ll use. Finally, compile the software and do your final install.

Versions 1.6 and Up and SASL

As mentioned earlier, the Cyrus SASL library is a prerequisite for Versions 1.6 and up of Cyrus IMAP. Make sure SASL is installed and configured before compiling Cyrus IMAP Version 1.6 or higher. SASL requires some configuration of its own. CMU recommends configuring SASL to use CRAM-MD5 on a single server, or GSSAPI for use on more than one server. You can also configure SASL to use the pwcheck daemon for cleartext Unix password authentication.

Unpack the Distribution

Assuming you’ve already downloaded Cyrus using a command similar in effect to:

%lynx –dump ftp://ftp.andrew.cmu.edu/pub/cyrus-mail/cyrus-imapd-v1.5.19.tar.gz \\
  > cyrus-imapd-v1.5.19.tar.gz

uncompress it, untar it, and you’ve got your source tree for Cyrus:

%ls -Fs
total 1048                        1048 cyrus-imapd-v1.5.19.tar.gz
% gunzip cyrus-imapd-v1.5.19.tar.gz
% ls -s
total 4688                    4688 cyrus-imapd-v1.5.19.tar
% tar xf cyrus-imapd-v1.5.19.tar
% ls -FaCs
total 4694                        2 cyrus-imapd-v1.5.19
   2 ./                        4688 cyrus-imapd-v1.5.19.tar
   2 ../

Setting Up Build-Time Configuration Options

Your first task is to decide on what options to use with the configure script. ...
