This also has the benefit that only one copy of mail is sent over
your IP connection, instead of one copy of every message for every
destination domain.

Postfix uses DNS by default. In order to use /etc/hosts you have
to turn off DNS lookups (and even then, what happens depends on
how the local naming service is configured).
