Parse mail tags programmatically

Hi all,

I want to parse (and maybe send) a mail with the content of a CF7 mail programmatically after a form was submitted.

I have this so far:

$submitId = '13659';
$formData = get_post_meta( $submitId, 'data', true ); //get submitted data
$form_id = '1267';
$wpcf7 = WPCF7_ContactForm::get_instance( $form_id ); //get the form
if( $wpcf7 )
{
	$props = $wpcf7->get_properties(); //get all props. from the form
	$dataArr = json_decode( $formData, true );
	if( $props['mail']['active'] ) //check if mail is active
	{
		//do the magic on the body part with the submitted content
		//something like:
		//$props['mail']['body'] = wpcf7_parse_tags( $props['mail']['body'], $dataArr );
	}
}

I mean, I could use 3 x foreach to replace all tags, but there will be tags missing like [_site_admin_email], [_site_title], …

Maybe someone has done something similar so far and can help me a bit or give me a hint.
