Depending where you use strings indicating truth values, the interpretation varies. Router conditions have a lax interpretation: "false" "no" and "0" are false, anything else is true. So "grey" would be true. In others, eg. ACL conditions, tighter rules apply. Specifically, for ACLs, you get a defer. This is documented. We're unlikely to change those rules; it would break valid configurations. -- Cheers, Jeremy -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
