The X.400/9000 product includes "x4mailer" to provide X.400 gateway
service to UNIX(r) mail users (a` la SMTP/RFC822/RFC987), besides being
an MTA.  x4mailer is to be used with "sendmail". Some configuration will be
needed.

Another product, HP OpenMail/X.400 Interface allows HP OpenMail product
to integrate with X.400/9000. HP OpenMail is X.400-based mail server.
One among HP OpenMail functionalities is X.400 User Agent application,
supporting terminal as well as PC interfaces.

Other products are needed for a complete OSI stack: OTS/9000 (for
Session and Transport), and X.25/9000 and/or LAN/9000 (for network
service). Only the HP X.400/9000 and the products for lower layers
are required for an RFC822/X.400 gateway.
