• Appendix B: Standards Conformance

Appendix B: Standards Conformance

The purpose of this appendix is to list the open standard protocols that are used by Post.Office. The idea behind open standards is that they are publicly available so anybody can implement them and inter-operate with other conforming software implementations. The Internet is built on the concept of open standards.

Since Post.Office is built on open standards, you are assured that it will work with other software products written to work on the Internet (or other TCP/IP networks) where these standards are used.

The Post.Office mail system conforms to the standards listed in this section. Every effort has been made to verify that Post.Office conforms completely with the specifications to ensure interoperability.

The letters "RFC" in all of the standard names mean Request for Comments. These are published protocol standards based on work done by working groups in the Internet Engineering Task Force (IETF).
