This extension is EXPERIMENTAL. The behaviour of this extension -- including the names of its functions and anything else documented about this extension -- may change without notice in a future release of PHP. Use this extension at your own risk.
This extension has been moved from PHP as of PHP 4.2.0 and now mailparse lives in PECL.
This PECL extension is not bundled with PHP. Additional information such as new releases, downloads, source files, maintainer information, and a CHANGELOG, can be located here: http://pecl.php.net/package/mailparse.
In order to use these functions you must compile PHP with mailparse support by using the --enable-mailparse configure option.
