| 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. | |
