[Exim] Exim 4 - String Expansion - Lookup

Upgraded to Exim 4 and this broke. What am I doing wrong and what do I
need to do to fix it?


bounce_spam_personal:
driver = redirect
allow_defer
allow_fail
data = :fail: "unknown user \"$local_part\" in domain \"$domain\""
require_files =
${lookup{$local_part}lsearch{/etc/vmail/passwd.$domain}{${extract{5}{:}{$value}}/.bouncelist}}
retry_use_local_part
senders =
${lookup{$local_part}lsearch{/etc/vmail/passwd.$domain}{${extract{5}{:}{$value}}/.bouncelist}}
