You need to change your hub router so that it checks for valid local parts
and sets the address data accordingly:

xyzhub:
        driver = manualroute
        domains = xyz.co.in
    local_parts = lsearch;/etc/exim/local_part_list
    address_data = $local_part
        route_data = <<one ip address>>
        transport = remote_smtp
