[Exim] explicit 'fail' item

Hello,

haven't found in the documentation how to add "explicit
'fail' item". I've tried:

new_address = "${lookup{*} lsearch {/etc/mail/domains/${domain}/globalredirect}{$value}{:fail:}}"
new_address = "${lookup{*} lsearch {/etc/mail/domains/${domain}/globalredirect}{$value}{fail}}"

neither worked...

Best regards,
 Andrey                          mailto:scriber@webclub.ru
