It's not entirely clear whether you want to accept the -owner and -subscribe
addresses and only reject mail to the main address, or if you want to reject
mail to all of them, but in any case, $local_part_suffix etc. only works in
routers. In ACLs the recipients condition matches the full address is checked
and $local_part is the entire local part. One suggestion is that you move
some logic to the routers and perhaps use address_data to pass list
closedness info back to the ACL.
