   local_parts = lsearch;DOMAINS_DIR/$domain/alias
   address_data = ${extract{field}{$address_data}} aliased=$local_part_data
   data = $local_part_data

You can just use ${extract {aliased} {$address_data} } here, since a
username is equivalent to true (unless you have some unusual usernames!).

I do this check in the ACLs rather than the routers, because messages may
come in to our email hub with a loadl user as the sender address for many
reasons other than message submission - email routing in Cambridge is
complicated, and there is lots of forwarding.
