Building Cyrus IMAP
===================

In this section, we only list the aspects of building Cyrus IMAP of
particular interest to most common deployment scenarios. For more
information on all "configure" options with full details, we refer you
to "./configure --help".


Required Software Components
============================

The following software components are required for Cyrus IMAP to build
at all, with minimal functionality;

* "autoconf"

* "automake"

* "zlib" (Development Headers)

Obviously, the list is not complete


Recommended Software Components
===============================

We recommend you consider building Cyrus IMAP with the following
software components included;


Idled Support
-------------

To enable near real-time client updates through IMAP IDLE (as
described in **RFC 2177**), configure Cyrus IMAP with the "--enable-
idled" option.


Murder Support
--------------

To enable horizontal scalability, Cyrus IMAP supports the distribution
of mailboxes across Cyrus IMAP servers in a Murder setup. To enable
murder support in Cyrus IMAP, configure Cyrus IMAP with the "--enable-
murder" option.


Replication Support
-------------------

To enable replication support in Cyrus IMAP, configure Cyrus IMAP with
the "--enable-replication" option.

Obviously, the list is not complete


Recommended Software Components Enabled by Default
==================================================


Sieve Support
-------------

Without any additional effort, Sieve support is already enabled by
default. To disable Sieve, use the "--disable-sieve" option to
"configure".


Optional Software Components
----------------------------

When including the following software components during the build
process, and providing the options listed here, additional optional
functionality can be implemented;

**MySQL** (Development headers)

To enable using MySQL as a database server backend, include the MySQL
development headers and make sure to configure Cyrus IMAP with "--
with-mysql".

Should MySQL - the client libraries or the development headers - be
installed in a non-standard location, please consider using any of the
following options;

   --with-mysql=DIR          use MySQL (in DIR) [no]
   --with-mysql-libdir=DIR   MySQL lib files are in DIR
   --with-mysql-incdir=DIR   MySQL include files are in DIR

**PostgreSQL** (Development headers)

To enable using PostgreSQL as a database server backend, include the
PostgreSQL development headers and make sure to configure Cyrus IMAP
with "--with-pgsql".

Should PostgreSQL - the client libraries or the development headers -
be installed in a non-standard location, please consider using any of
the following options;

   --with-pgsql=DIR          use PostgreSQL (in DIR) [no]
   --with-pgsql-libdir=DIR   Pgsql lib files are in DIR
   --with-pgsql-incdir=DIR   Pgsql include files are in DIR

Obviously, the list is not complete
