(1) Architectural layers are a protocol design construction, only, which assist with standardization. They are not a separation of responsibilities. A SMTP server has to take care to have an implementation of all layers. Further: A well designed SMTP server has to be built with some understanding of all layers involved, they are used to construct Received: headers, and a SMTP server cannot treat the application layer in isolation. It is a complete and utter fiction, to suppose that the layers can be treated in total isolation. (2) The IP protocol layer is not actually independent. Moving to IPv6 does in fact have effective new requirements for SMTP servers. (3) Abuse transcends all layers, and so does the administration of any service provided by an application. (4) When a major change will [by necessity] be made to any layer underlying the MTA application on the protocol stack, now is also a good time to look at the overall service as a whole. -- -JH
