Networking and Communication
Concepts
OpenVMS pioneered many networking and communication technologies. Networks evolved from novelties to something like a public utility (the Internet) in the past 30 years. Networks allow sharing of resources and remote communication. OpenVMS Mail can now be accessed from PCs using popular mail protocols, such as the Post Office Protocol (POP) and more recently the Internet Mail Access Protocol (IMAP, on systems configured with TCP/IP Services for OpenVMS 5.3 or later). The proprietary DECnet protocols, still supported on OpenVMS as DECnet-Plus, have been superseded on many systems by TCP/IP protocols, primarily because of the rapid growth of the Internet and the World-Wide Web. OpenVMS Mail is also useful for user-to-user communication on a local system. Other utilities and commands provide additional mechanisms for user-to-user communication.
