As documented, the above is not valid main.cf syntax. Perhaps
you were looking for:
show_user_unknown_table_name (default: yes)
Display the name of the recipient table in the "User unknown"
responses. The extra detail makes trouble shooting easier but also
reveals information that is nobody elses business.
This feature is available in Postfix 2.0 and later.
