Problem with send a copy to yourself

I do everything as described —- http://wordpress.org/support/topic/send-a-copy-to-yourself-chackbox?replies=2

1. add in function.php

`
add_filter( 'wpcf7_additional_mail', 'my_wpcf7_use_mail_2_or_not', 10, 2 );
	function my_wpcf7_use_mail_2_or_not( $additional_mail, $cf ) {
		if ( "Отправить копию этого сообщения на ваш email" != $cf->posted_data['contact_sendmail'][0] )
			$additional_mail = array();
	return $additional_mail;
}	`

2. add in Form editing field

[email* your-e "E-MAIL"]
[checkbox contact_sendmail default:1 use_label_element "Отправить копию этого сообщения на ваш email"]

3 “Use Mail(2)” – To: [your-e] – does not work
and tried Use Mail(2) – “Additional headers:” – Bcc: [your-e] — oes not work too

Tell me what I’m doing wrong?
