   * Send mail, similar to PHP's mail
   *
   * A true return value does not automatically mean that the user received the
   * email successfully. It just only means that the method used was able to
   * process the request without any errors.
   *
   * Using the two 'wp_mail_from' and 'wp_mail_from_name' hooks allow from
   * creating a from address like 'Name <email@address.com>' when both are set. If
   * just 'wp_mail_from' is set, then just the email address will be used with no
   * name.
   *
   * The default content type is 'text/plain' which does not allow using HTML.
   * However, you can set the content type of the email by using the
   * 'wp_mail_content_type' filter.
   *
   * If $message is an array, the key of each is used to add as an attachment
   * with the value used as the body. The 'text/plain' element is used as the
   * text version of the body, with the 'text/html' element used as the HTML
   * version of the body. All other types are added as attachments.
   *
   * The default charset is based on the charset used on the blog. The charset can
   * be set using the 'wp_mail_charset' filter.
   *
   * @since 1.2.1
   * @uses apply_filters() Calls 'wp_mail' hook on an array of all of the parameters.
   * @uses apply_filters() Calls 'wp_mail_from' hook to get the from email address.
   * @uses apply_filters() Calls 'wp_mail_from_name' hook to get the from address name.
   * @uses apply_filters() Calls 'wp_mail_content_type' hook to get the email content type.
   * @uses apply_filters() Calls 'wp_mail_charset' hook to get the email charset
   * @uses do_action_ref_array() Calls 'phpmailer_init' hook on the reference to
   *    phpmailer object.
