- The Merit staff operates a gateway between the Internet and
- SprintMail, which allows messages to be exchanged between
- SprintMail customers and Internet users. The gateway is
- connected to Sprintnet and to the Internet through Merit's
- connections to the NSFNET.
-
- SprintMail, operated by Sprint International, is a commer-
- cial X.400 electronic mail network providing services to US
- customers and access to other networks domestically and
- internationally. Formerly known as Telemail, SprintMail
- uses the Sprintnet (formerly Telenet) public data network
- for its e-mail connections.
-
- Merit provides hardware and software maintenance and
- administration and network operations (via the Merit Network
- Operations Center) for the Internet gateway; Sprint provides
- Sprintnet connectivity and user consulting and registration,
- as well as gateways to other X.400 networks.
-
- The gateway is a Sun SPARCstation-I running Sun OS 4.0.3 and
- Sunlink MHS. An X.25 link to Sprintnet is connected to the
- Sun's serial port at 9600 bps. Protocols used are X.400
- Message Handling System, X.225 session layer, X.224 tran-
- sport class 0, and X.25. On the Internet side, the Simple
- Mail Transfer Protocol (RFC-822), Transfer Control Protocol,
- Internet Protocol, and Ethernet protocols are used.

- The gateway supports a directory function that allows
- SprintMail customers to be registered with a mnemonic name
- which can be used by Internet users when sending mail.
- SprintMail users who wish to register can contact Sprint
- Customer Service.
-
- Merit provides domain name service for the SPRINT.COM domain
- as well as for some other domains on behalf of some
- SprintMail customers. For example, the COMPMAIL.COM domain
- is owned by the IEEE (Institute of Electrical and Electronic
- Engineering) Computer Society but is operated by Merit as
- part of the gateway function.

-
- From the Internet to SprintMail
- To use the gateway, an Internet user can specify a
- registered SprintMail alias name, in the form:
-
- John.Doe@Sprint.COM
-
- Alternatively, the full X.400 Originator/Recipient (OR) name
- can be specified, (all on one line), for example:
-
- /pn=John.Doe/admd=Telemail/o=Sprintintl/c=us/@Sprint.COM
-
- The Internet host name after the at-sign, @, can be
- SPRINT.COM or another domain supported by the Merit gateway.
- X.400 OR names consist of a list of parameters and their
- values. X.400 parameters in OR names that can be used by
- the SprintMail gateway include:
-
-
- ADMD Administrative Management Domain
- PRMD Private Management Domain
- PN Personal Name
- G Given Name
- S Surname
- DD.UN User Name (DD is "Domain Defined")
- O Organization
- C Country (two-letter abbreviations must be used, for example, US, GB, JP)
-
-
- From SprintMail to the Internet
- When sending mail from the SprintMail X.400 environment to
- the Internet, the native syntax of the sender's system
- should be used. Use an "ADMD" of TELEMAIL, "PRMD" of INTER-
- NET and "Country" of US, along with the "RFC-822" "domain

- defined" attribute to specify the user's Internet mail
- address. For example, to send mail from the SprintMail sys-
- tem to an Internet user whose address is
- jdoe@engin.college.edu, type (all on one line):
-
- (Site:Internet,ID:<jdoe(a)engin.college.edu>)
-
- The angle brackets "< >" are required. The "(a)" replaces
- the at-sign, @, because that and most other special charac-
- ters are illegal as specified in RFC 987, which makes it
- necessary to substitute "(u)" for underscore, _, "(b)" for
- bang (exclamation point), !, "(q)" for a quotation mark, ",
- and "(p)" for percent, %.
-
- Resolving Problems
-
- If a message sent across the gateway cannot be delivered,
- the gateway will send a return message to notify the sender
- of nondelivery. That notification message will explain the
- problem with the mail address. If you have further ques-
- tions, call or send e-mail to Sprint Customer Service.
