|
| 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. |
