Validating textarea with 2 conditions Contact Form 7

I'd like to execute 2 tests on a textarea within a CF7 form.

First: the textarea does not contain an url

Second: the same textarea does not contain email address

I tried this code:

function custom_textarea_validation_filter($result, $tag) {
$type = $tag['type'];
$name = $tag['name'];
if($name == 'yourmessage') {
$value = $_POST[$name];
if(preg_match("/\b(?:(?:https?|ftp|http):\/\/|www\.)[-a-z0-9+&@#\/%?=~_|!:,.;]*[-a-z0-9+&@#\/%=~_|]/i",$value)||preg_match("#^[a-z0-9._-]+@[a-z0-9._-]{2,}\.[a-z]{2,8}$#",$value)){ 

    $result->invalidate( $tag, "Merci de ne pas inclure de liens, url, ou adresse email !" );
                }
}
return $result;
}
add_filter('wpcf7_validate_textarea','custom_textarea_validation_filter', 10, 2);
add_filter('wpcf7_validate_textarea*', 'custom_textarea_validation_filter', 10, 2);

yourmessage is the textarea I want to test

But it does not work well: url are detected but not email adress... I can't create two funtions because if the first evaluation is ok, the second is useless.

Thanks for any advices. Gromit

So, for anyone interested in implementing this kind of filter (url and email address in textarea in a Contact Form7 form - wordpress):

function custom_textarea_validation_filter($result, $tag) {  
$type = $tag['type'];
$name = $tag['name'];
if($name == 'yourmessage') {
$value = $_POST[$name];
$Match_all = "/\b(?:(?:https?|ftp):\/\/|www\.)[-a-z0-9+&@#\/%?=~_|!:,.;]*[-a-z0-9+&@#\/%=~_|]|[a-z0-9._-]+@[a-z0-9._-]{2,}\.[a-z]{2,8}/";
if(preg_match($Match_all,$value)){

    $result->invalidate( $tag, "Merci de ne pas inclure de liens, url, ou adresse email !" );
                }
}
return $result;
}
add_filter('wpcf7_validate_textarea','custom_textarea_validation_filter', 10, 2);
add_filter('wpcf7_validate_textarea*', 'custom_textarea_validation_filter', 10, 2);

Thanks to "The fourth bird" for having helped me !
