It looks like there may finally be a SMTP for the IBM VM world.

Text:
The University of Wisconsin has implemented the DOD Internet
protocols (FTP/SMTP/Telnet/TCP/IP) for IBM VM systems under con-
tract to IBM. This software package, called WISCNET, is owned by
IBM. IBM has licensed Wisconsin to distribute WISCNET to univer-
sities and colleges. Source code will be included with the dis-
tribution, which will begin in mid-June.
To receive WISCNET, a university or college must sign a
license agreement with the University of Wisconsin and pay a
one-time distribution fee of $500. Licenses may be obtained from
and should be returned to:
Lawrence H. Landweber
Computer Science Department
University of Wisconsin - Madison

Madison, WI 53706
ARPANET, CSNET: landweber@wisc-rsch.ARPA
UUCP: ...!{seismo,allegra,ihnp4}!uwvax!landweber
Documents describing WISCNET will be sent with licenses.
BRIEF OVERVIEW OF WISCNET
WISCNET includes:
(1) An implementation of the standard DOD protocols TCP and IP
under VM/SP Release 2 or 3.
(2) Implementations of the higher-level DOD protocols FTP, SMTP,
and Telnet.
(3) An interface between SENDFILE and SMTP.
(4) Interfaces from IP to the Ethernet and Pronet local area
networks (using a DACU as described below).
(5) An interace from IP to the Telenet public data network
(using a Series/1 as described below).
TCP/IP runs in a separate disconnected virtual machine on
the VM host. Similarly, each of SMTP, server FTP, and server
Telnet occupies a dedicated virtual machine. User FTP and user
Telnet run within a user's virtual machine under CMS. Virtual
machines communicate with one another using the Virtual Machine
Communication Facility (VMCF).
The VM software is written almost entirely in Pascal, with a
small amount of assembler-language support. Standard IBM-released
software is used throughout (i.e., no modified or unreleased sys-
tem software has been employed).
Local area network interfaces are available for Pronet (Pro-
teon Corp. - 10 Megabit/sec token ring) and Ethernet (Interlan -
10 Megabit/sec). The IBM host is connected to these local area
networks via a Device Access Control Unit (DACU), which is a
UNIBUS-to-channel adapter sold by IBM. There is also an inter-
face to the Telenet public data network, using an X.25 implemen-
tation running on a channel-attached Series/1 front end running
the RPS operating system. The latter interface allows CSNET IBM
VM hosts to connect to the DARPA Internet via Telenet.
