The pre-packaged products are called OpenServer 400, and exist for DOS, UNIX (ISC or SCO) and OS/2. DOS and UNIX support X.25 and CLNS; OS/2 supports X.25 only. RFC1006 is supported by the UNIX versions.
There are also gateways from OpenServer 400 to: SMTP (MG-130) (claims conformance to RFC-987 only) Novel MHS (MG-150) Oracle Mail (MG-170) WordPerfect Office (MG-180) Microsoft Mail for the Mac (MG-190) and Microsoft Mail for the PC (MG-195) CC:mail for the PC (MG-170) is shipping. The QuickMail gateway (MG-140) is shipping. Retix X400 to Lotus Notes gateway is in Beta Test.
The newer gateways have AutoRegistration of incoming X.400 addresses so that the user/admin can respond to addresses similar to what they would normally see in the proprietary mail system. We also have Directory eXchange (DX) for directory synchronization with the Retix OpenServers.
