Pedant: transports deliver, the directors send the mail to the correct
transport (or re-write the address ;)

The system on the internal box in the office is a prime example of
bastard directors and transports, everything gets tossed through
spamassassin and then the cardiff alias file get applied which re-writes
based on a smartuser director and then everything else hits a domain
specific alias file anything which gets through that bounces (yes I can
see the ineffciencies but it works at the moment so I'm not fixing it :)

Of course we throw many of the concepts away with exim4, so who's
playing with that at the moment? :)
