+/**
+ * Identity selection based on additional message headers.
+ *
+ * On reply to a message user identity selection is based on
+ * content of standard headers i.e. From, To, Cc and Return-Path.
+ * Here you can add header(s) set by your SMTP server (e.g.
+ * Delivered-To, Envelope-To, X-Envelope-To, X-RCPT-TO) to make
+ * identity selection more accurate.
+ *
+ * Enable the plugin in config.inc.php and add your desired headers:
+ *   $rcmail_config['identity_select_headers'] = array('Delivered-To');
+ *
