Yes, we do have an X.400 implementation called Ean which was developed here at the University of British Columbia (UBC). It is used in the Canadian OSI network CDNnet, and it is also used in several OSI networks in other countries. The software is an implementation of X.400(1984), including both a Message Transfer Agent (MTA) and a User Agent (UA). The main UA is a line-at-a-time program, although interfaces for the Macintosh (from the University of Oslo) and for X are being developed. Also included in an X.400/RFC-822 gateway. This corresponds somewhat to the mappings specified in RFCs 987 and 1026, especially in the area of address mapping, although our gateway software predates the RFCs and does not attempt to conform in detail. The UA--a version not yet being distributed--can present addresses to the user in either the X.400 attribute style, or in the RFC 822 style (thanks to work done at Trondheim, Norway and by GMD in West Germany). The main platforms for Ean are UNIX (mainly BSD) and VMS. For inter-MTA communications, Ean supports the use of TP0/X.25, TP0/asynch, TP0/DECNET, and TP0/TCP (both RFC 1006 and our own encapsulation). We are presently testing the software for use with Telecom Canada's commerical e-mail service Envoy. We have experienced no major problems with the testing so far. The software is used in production. One example is its use at UBC, where CDNnet has its headquarters. There are MTAs in approximately 25 departments. The hub MTA is relay.cdnnet.ca which is also the main hub for CDNnet, and acts as an e-mail gateway into the Internet. The hub is fairly busy: an average day sees approximately 10000 messages in+out. (By way of comparison, I believe that traffic through the CSNet hub is about twice as great.) The relay.cdnnet.ca host is presently a Sun-3/60 with 8M of memory and a Wren V disk. CDNnet acts on behalf of UBC to license and distribute Ean to academic organizations. We are presently trying to get permission to license the software more widely for noncommercial use. The commercial rights to Ean are held by OSIware (+1 604 436 2922). Also, we are trying to get UBC approval to license Ean to the University of Wisconsin for possible use in their NASA-supported X.400 pilot in the Internet. UBC is currently testing its own X.500 implementation. This development has been directed by Gerald Neufeld (who designed Ean/X.400) and includes staff from UBC Computer Science, CDNnet, and OSIware. The Ean software package includes an X.25 kernel implementation for BSD UNIX. I believe negotiations are under way to have some of this software included with 4.4BSD. The main configurations supported are the Vax with a DMF32, and the Sun3 with its A/B ports (under SunOS 4.0.1). Incidentally, I do not know how much longer CDNnet will be around. Support for our OSI network is decreasing. I think a major factor is the rapid rise of interest in Internet-style networking in Canada, as evidenced by the forthcoming Canadian IP backbone network CA*net and the establishment of Canadian regional networks. In any case, I expect that UBC and OSIware will continue to develop, license, distribute, and support UBC's OSI software.
