As documented, the DISCARD action discards the message, not the
recipient. To drop only the recipient, use transport_maps to send
the recipient to the discard(8) service.
/etc/postfix/main.cf:
transport_maps = hash:/etc/postfix/transport
/etc/postfix/transport:
u...@example.com discard:
After changing the file, do "postmap hash:/etc/postfix/transport".
To discard a recipient based on localpart, use a pcre table instead;
this requires no postmap command.
/etc/postfix/main.cf:
transport_maps = pcre:/etc/postfix/transport
/etc/postfix/transport:
# The ^ at the beginning is required to avoid false matches.
/^user@/ discard:
Of course this will have collateral damage; it discards mail for
recipients in unrelated domains.
