Depending on the show_user_unknown_table_name parameter setting, Postfix
replies with one of the following:
550 5.1.1 <u...@example.com>: Recipient address rejected: user unknown
550 5.1.1 <u...@example.com>: Recipient address rejected: user unknown in local
recipient table
550 5.1.1 <u...@example.com>: Recipient address rejected: user unknown in
virtual alias table
550 5.1.1 <u...@example.com>: Recipient address rejected: user unknown in
virtual mailbox table
550 5.1.1 <u...@example.com>: Recipient address rejected: user unknown in relay
recipient table

This is not documented, therefore it is not implemented.
