EIMS Glossary of TermsDocument ID: 2148HQ
Alias: Another name for an existing users address.
Application Configuration Access Protocol (ACAP): ACAP is a protocol that allows applications to store and retrieve arbitrary configuration data from a central server.
APOP: Authenticated Post Office Protocol is an MD5-based login command that does not send passwords in clear text over the network.
Body: The part of an e-mail message that contains the main text of the message. The body can contain text, graphics, sound, and video clips.
Browser: A World Wide Web client that is able to send and receive messages using HTTP and read and format HTML documents.
Client: A computer or software program that accesses resources over the Internet. It is also an application that requests a server to perform a function. In the Internet mail environment, the term client indicates a mail user agent, for example, Eudora.
Custom domain: An Internet Mail component that is configured with special routing information for SMTP mail settings. Multiple custom domains can be configured; messages sent to a custom domain are handled and routed according to its specifications, i.e., through static routes or gateways. Custom domains are added and configured on the Sending setup preferences in the EIMS Admin tool.
Domain: In general, a group of computers and other devices under the management of a single administrator or administrative entity. In the Internet, a domain identifies a range of IP addresses and mail-forwarding information. See DNS.
DNS: Domain Name System. The naming service used by Internet Mail to support message routing. It maps domain addresses to IP addresses so Internet messages can be delivered to a particular server. It is also used extensively to map machine addresses to IP addresses.
Envelope: The part of an e-mail message that contains the information needed to forward a message to the recipients. The envelope is important to messaging servers and is not usually seen by users.
Gateway: In general, software that translates information between one protocol and another.
Header: The part of an e-mail message that precedes the message. It contains information such as the originator, recipient, and subject of the message.
Home page: An HTML document that resides in a data directory and is the primary starting point for anyone navigating that directory. It is possible to create multiple home pages by configuring virtual paths. In this way, it is possible to assign a different home page for each directory that a virtual path references.
HTML: Language used to create Web pages. A Web client interprets HTML and displays documents and graphics accordingly. HTML also allows document authors to establish hypertext links between documents in various locations on the Internet and to create forms and image maps that enable users to interact with Web documents.
HTTP: The standard way of transferring information across the World Wide Web. It supports a variety of media and file formats across a variety of platforms.
IAB: Internet Activities Board. The organization (within the U.S. Department of Defense) that is charged with administering the Internet.
IETF: Internet Engineering Task Force. The standards-setting body of the Internet. Internet. A giant, global network made up of many smaller networks, all connected using the TCP/IP protocol.
Internet directory: A directory that runs over TCP/IP and is widely implemented on the Internet. A directory implementing Ph, such as EIMS, is an Internet directory.
Internet Directory server: An EIMS server component that maintains Internet Mail user information in an Internet (Ph) directory where it can be viewed from the EIMS Admin tool or Ph client such as Eudora.
IP address: The address that serves as a unique identifier of computers on the Internet. IP addresses have the following format: 22.214.171.124 - The DNS converts IP addresses to the more familiar domain names.
ITU-T: The International Telecommunication Union, formerly the Consultive Committee for International Telegraphy and Telephony (CCITT), is responsible for communications, telecommunications, and networking standards throughout the world.
Lightweight Directory Access Protocol (LDAP): LDAP is a protocol that provides an online, fully indexed, fast-access white-pages directory service developed and freely distributed by the Regents of the University of Michigan. LDAP is included in EIMS directory server.
Mailbox: A directory that stores messages for a single user.
Mailbox user: An Internet Mail user who uses a remote client to send and receive messages.
Mailing list: A group of recipients to whom users can refer by a common name (for example, a mailing list called Marketing). When users address a message to a mailing list, all members of the mailing list receive the message.
MIME: Multi-Purpose Internet Mail Extensions. A set of extensions to the Internet Mail standards that supports the inclusion of multi-part and multimedia files, such as sound and video, in e-mail messages.
MX Record: Acronym for Mail eXchange. MX is a DNS record used to define the host(s) willing to accept mail for a given machine.
Network: A group of connected computers that can communicate with one another. Networks enable computers to share files and resources and exchange messages.
Ph: Ph (Phone book) is an online, fully indexed, fast access white-pages directory service developed and freely distributed by the Computer and Communications Services Office at the University of Illinois at Urbana. The EIMS server supports Ph in its directory server.
POP3: Post Office Protocol 3. A protocol that provides a simple, standardized way for users to access mailboxes and download messages to their computers.
Postmaster: A special type of user responsible for tracking failed mail delivery. A post-master is responsible for following up on queries from users and other postmasters. Internet standards require that the postmaster account be valid at every domain.
RFC: In the Internet community, Request For Comments are the working notes of the Internet research and development community. These documents contain protocol and model descriptions, experimental results, and reviews. All Internet standard protocols are written up as RFCs.
Server: An entity that provides a network service. A server can be hardware (such as a file server), software (such as a mail server), or services (such as a transportation service). A mail server is a program that accepts, relays, and delivers mail.
SMTP: Simple Mail Transfer Protocol. The protocol widely implemented on the Internet for exchanging e-mail messages.
Static mail route: A mail route that an administrator explicitly specifies on a particular domain. Static routes bypass domain name systems (DNS).
