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
     1210 W. Dayton St.
     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.
