man 5 postconf

relay_recipient_maps (default: empty)
Optional lookup tables with all valid addresses in the domains that
match $relay_domains. Specify @domain as a wild-card for domains that
have no valid recipient list, and become a source of backscatter mail:
Postfix accepts spam for non-existent recipients and then floods inno-
cent people with undeliverable mail. Technically, tables listed with
$relay_recipient_maps are used as lists: Postfix needs to know only if
a lookup string is found or not, BUT IT DOES NOT USE THE RESULT FROM
TABLE LOOKUP.
