MVS UCLA Mail

Overview of UCLA/Mail (and IPC/370)

UCLA/Mail is a mail system for IBM's MVS operating system. It interfaces to the network via a SNA/NJE connection to JES2. If your system has a compatible TCP/IP product and a SMTP daemon which interfaces to NJE and is compatible with UCLA/Mail, then UCLA/Mail can handle Internet mail. UCLA/Mail, itself, does not use TCP/IP.

IPC/370 allows normal problem mode programs to communicate between MVS address spaces. This is used by the mail agents (including a TSO mail command) to communicate with the UCLA/Mail address space. It can also be used for other purposes.

UCLA/Mail and IPC/370 were written in 370 assembly language. You'll have to look elsewhere for C source code.

Current Status

UCLA/Mail never had support, however in the past we have responded to questions from other sites with the idea that this would help us run it here.

We are no longer running MVS and must end our involvement with anything related to MVS including UCLA/Mail. So there will not be any further distributions or modifications of UCLA/Mail (or IPC/370) from UCLA. Questions about UCLA/Mail will not be answered.

Any e-mail addresses which used to exist on host mvs.oac.ucla.edu no longer exist.

To allow other sites to field questions and continue development of UCLA/Mail, the UCLA/Mail and IPC/370 source is being made available under a "Berkeley" type license. This allows others to redistribute UCLA/Mail and IPC/370.
