- The Internet Gateway
- ~~~~~~~~~~~~~~~~~~~~
- The Internet Gateway provides Internet e-mail users with a method of
- communication to AT&T Mail. The Interconnect consists of various private
- email networks and uses an addressing format better know as Domain Addressing
- Service (DAS).
-
- A domain address consists of a user name, followed by an @ sign and/or % sign
- and a domain name, which is usually the system name.
-
- Example:
-
- jdoe@attmail.com
-
- Sending Email to Internet Users
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- To send email from the AT&T MailService to the Internet community use the UUCP
- addressing style.
-
- Example:
-
- internet!system.domain!username
-
- Translates to:
-
- internet!gnu.ai.mit.edu!jdoe
-
- If you are sending e-mail to an Internet user whose e-mail address may be in
- the RFC 822 format (user@domain), you must translate the RFC address before
- sending your message to an Internet recipient.
-
- username@system.domain (Internet user's address)
-
- internet!system.domain!username (to a UUCP address)
-
- Example:
- username%system2@system.domain (Internet user's address)
-
- Translates to:
- internet!system.domain!system2!username
-
- Sending Email From The Internet
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- To send email to the AT&T Mail Service, Internet users can choose either the
- RFC 822 or UUCP addressing style. The Internet recognizes attmail.com as the
- domain identifier for AT&T Mail when electronic messages are sent through the
- gateway. Although many Internet users choose to send e-mail using the RFC 822
- addressing style, the UUCP style is also available on many UNIX systems on the
- Internet, but not every system supports UUCP. Below are examples of both
- addressing styles:
-
- RFC 822 Addressing: username@attmail.com
-
- Example:
-
- jsmith@attmail.com
-
- UUCP Addressing: attmail.com!username
-
- Example:
-
- attmail.com!jdoe
-
- Although email can be sent through the Internet gateway, surcharged services,
- such as Telex, FAX, COD, U.S. Mail, overnight, urgent mail and messages
- destined to other ADMDs connected to AT&T Mail are not deliverable. If you are
- an Internet e-mail user attempting to use a surcharged service and are not
- registered on AT&T Mail, you will not be able to send your message, and will be
- automatically notified. Below is a list of surcharged services that are
- unavailable to Internet users.
-
- * FAX
- * Telex
- * COD
- * U.S. Mail
- * Overnight
- * Administrative Management Domain (ADMD) Messages
-
- Sending Email to Bitnet Users
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- To send email to BITNET users from AT&T Mail, enter:
-
- internet!host.bitnet!user
-
- Sending Email to UUNET Users
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- To send email to UUNET users from AT&T Mail via the Internet Gateway, enter:
-
- attmail!internet!uunet!system!user
-
- Internet Restrictions
- ~~~~~~~~~~~~~~~~~~~~~
- The following commercial restrictions apply to the use of the Internet Gateway.
-
- * Users are prohibited to use the Internet to carry traffic between commercial
- (for profit) electronic messaging systems.
-
- * Advertising and soliciting i.e., messages offering goods or services for sale
- or offers of jobs.
-
- * Provision of for-profit service, other than electronic messaging to Internet
- users, is permitted (e.g., database services) if such service is used for
- scholarly research purposes and its costs are borne by individual or
- institutional subscription.
