FWIW, the following is not explained as clearly in the Postfix
documentation as one might wish, and it would be good to have better
coverage of this topic in the docs (in the appropriate places):
- What is a delivery agent?
- How are they related to transports?
- Which Postfix components are delivery agents?
- What is an internal service (that is not a delivery agent)?
- What are the various internal services?
- What are the "..._service" parameters, and in what context
can they be used (correctly)?
Some of this is in http://www.postfix.org/OVERVIEW.html, but the
taxonomy of internal services is not explicitly presented.
