Previously, a single lookup that checked both local part and domain to

Use two lookups, one for local_parts and one for domains, even if both
perform the same lookup, to set $local_part_data and $domain_data as
side effect, and things are easy from there.
That's the clean way. It is possible to finesse a single DB lookup,
if you are concerned by lookup costs: use the address_data option
with a lookup returning multiple columns on success and a forced-fail
otherwise (causes the router to decline). Then $address_data will
get a key=value list with column names as keys; you can pull single
items out using ${extract }.
This assumes only zero or one row returns.
