By reasonably recent versions of Linux, we intend to indicate the Cyrus project can keep up with the latest distribution release earmarked stable.

## 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
