I found a solution :
into the wp-login.php, i modified the following code on line 332
$message .= '<' . network_site_url("wp-login.php?action=rp&key=$key&login=" . rawurlencode($user_login), 'login') . ">\r\n";

by

$message .= '' . network_site_url("wp-login.php?action=rp&key=$key&login=" . rawurlencode($user_login), 'login') . "\r\n";

In fact, remove the <>.
