Odd deny condition failure behaviour

deny
condition = \
${lookup{\
${substr_18:$local_part}\
}lsearch{/etc/exim/conf/$domain/disabled_tags}{yes}fail}

Why does this act as though condition evaluated to true and continue? (The lookup key doesn't exist in the file).


check condition = ${if eq{${lookup{$domain}lsearch{/etc/exim/conf/domains}}}{tagged}{yes}{no}}
= yes
search_open: lsearch "/etc/exim/conf/DOMAIN/disabled_tags"
search_find: file="/etc/exim/conf/DOMAIN/disabled_tags"

internal_search_find: file="/etc/exim/conf/DOMAIN/disabled_tags"

in /etc/exim/conf/tagged
lookup yielded: key=KEY url=URL
deny: condition test succeeded

Philip decided that it would be useful if forced expansion failure in an ACL
condition meant that the condition be ignored. It's in the documentation. If
you really want a negative result, use "no" or "" instead.
