What is the output of: postconf smtpd_reject_unlisted_recipient Reason I ask is that the "unlisted recipient" check also does the relocated check. Wietse smtpd_reject_unlisted_recipient (default: yes) Request that the Postfix SMTP server rejects mail for unknown recipient addresses, even when no explicit reject_unlisted_recipient access restriction is specified. This prevents the Postfix queue from filling up with undeliverable MAILER-DAEMON messages.
