Postfix mail transport agent TCP map protocol implementation.
Receive requests for data matching given key via lineReceived,
asks it's factory for the data with self.factory.get(key), and
returns the data to the requester. None means no entry found.
You can use postfix's postmap to test the map service::
/usr/sbin/postmap -q KEY tcp:localhost:4242
