Another advantage of the multiple-file approach is that other packages
which need to receive e-mail (mailman, request-tracker, cabot for
example) could simply drop their transport/router combination into
/etc/exim4/conf.d and have them picked up by exim automatically. There
is currently no package doing this, but the possibility is there.

The disadvantage is that all packages dropping configuration bits into
/etc/exim4/conf.d need to coordinate a little bit, since exim does not
like configuration options being specified multiple times (having an
option twice is an error, instead of adding both values, or have a
first-served or a last-served approach). So, if exim4-config has
/etc/exim4/conf.d/routers/300_exim4-config_mailman specifying a router
called "mailman", and mailman suddenly starts bringing its own mailman
router in /etc/exim4/conf.d/routers/300_mailman_mailman, exim will
break because there are two mailman routers.

Really big sites will probably roll their own exim4-config package if
they bother to see what advantages that will bring to them.
