Address Book.

The Address Book is where you keep information about individuals or groups that you correspond with.


Another name for an existing user's address. In Eudora, an alias is also called a nickname.

Application Configuration Access Protocol (ACAP).

ACAP is a protocol which allows applications to store and retrieve arbitrary configuration data from a central server.


Any file can be attached to and sent with a Eudora message. Most of the time, an attached document functions like a "rider" to the e-mail message, and does not appear within the message text. Instead, the name of the document is displayed automatically in the Attached field in the message header.

Authenticated Post Office Protocol (APOP).

APOP is an MD5-based login command that does not send passwords in clear text over the network.


You can control and exchange information with Eudora from other programs that support the Windows Automation Interface, such as Microsoft Visual Basic. These options give you external access to Eudora mail folders, mailboxes, and messages, and to the Eudora application itself.


This is an attachment decoding method best used for recipients on a Macintosh with an e-mail reader that is not MIME-compliant.

Blind Carbon Copy (Bcc).

In this header field, you enter e-mail addresses or nicknames of people to whom a blind copy of the message is to be sent. These recipients are not displayed in the message header, and the recipients in the To or Cc fields will not know that a copy went to these addresses.


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.


A World Wide Web client that is able to send and receive messages using HTTP and read and format HTML documents.

Challenge-Response Authentication Mechanism-Message Digest 5 (CRAM-MD5).

The CRAM-MD5 algorithm is an encryption strategy for exchanging passwords between the Internet mail server and a client. Using CRAM-MD5, passwords are not sent in clear text.


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 Pro.


Daemons are generally server programs. They run continuously and are available when clients wish to initiate a session. However, an SMTP daemon periodically acts as a client when it needs to forward messages that are not to be delivered locally.

Dialup Networking.

This is a specified dialup connection (referred to in Windows NT 4.0 as a "phonebook entry") used when Eudora does any network operation. This option is available only if you have installed the dial-up networking services with Windows 95 or Windows NT 4.0.

Distribution list.

A group of recipients to whom users can refer by a common name (for example, a distribution list called Marketing). When users address a message to a distribution list, all members of the distribution list receive the message.


In general, a group of computers and other devices under the management of a single administrator or administrative entity. In Windows NT, a domain is a group of servers that share common security policy and user account databases. In the Internet, a domain identifies a range of IP addresses and mail-forwarding information. See DNS.

Domain Name System (DNS).

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.


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.

File Transfer Protocol (FTP).

Using this protocol, you can transfer files over the Internet.


A filter in Eudora sorts your mail as it is being delivered. You set up filter parameters for your specific needs, for example, all messages from your father can be filtered to your mailbox named DAD.


This is a directory services protocol. The Finger protocol is a server that allows you to search for a personís information, such as e-mail address, phone number, etc.


This is a file you create in Eudora where you can add mailboxes. You can name folders, for example FAMILY and your mailboxes can be named DAD, MOM, SIS, etc.

Folder Carbon Copy (Fcc).

You use Fcc to place a copy of your message in a mailbox or folder you designate.


This a Eudora function where you can forward an incoming message and its attachments to another person.


In general, software that translates information between one protocol and another.


The part of an e-mail message that precedes the message. It contains information such as the originator, recipient, and subject of the message. Also, it is used as an individual header filed, such as the To header.

Home page.

An HTML document that resides in a data directory and is the primary starting point for anyone navigating that directory.

Hyper Text Markup Language (HTML).

HTML is 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. Eudora uses HTML to send and receive styled text.

Hyper Text Transfer Protocol (HTTP).

HTTP is 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.


A giant, global network made up of many smaller networks all connected using the TCP/IP protocol. The Internet is the network of networks which spans the globe. TCP/IP is generally the network and transport protocol stack used to connect networks, but protocol translating gateways enable non-TCP/IP networks to connect to the Internet as well.

Internet directory.

A directory that runs over TCP/IP and is widely implemented on the Internet. A directory implementing Ph, LDAP, and Finger is an Internet directory.

Internet Engineering Task Force (IETF).

IETF is the standards-setting body of the Internet.

Internet Message Access Protocol (IMAP).

IMAP allows Eudora to access and manipulate electronic mail messages on a server, and it permits manipulation of remote mailboxes so they function like local mailboxes. IMAP4 provides a richer and more complex set of functionality than the POP3 protocol. IMAP is also called an Incoming server.

Internet Service Provider (ISP).

An ISP is the organization or company that provides you with Internet access and e-mail availability. For example, America Online (AOL) is an ISP.

IP address.

The address that serves as a unique identifier of computers on the Internet. It is a sequence of four small integers (each less than 256). When written, the numbers are separated by periods, for example: The DNS converts IP addresses to the more familiar domain names.


This is a programming language that allows software developers to write programs to run on any computer platform, regardless of the operating system.


This is one of many authentication systems Eudora uses. If your network uses Kerberos for authentication, the appropriate options are provided by your e-mail administrator.

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 Eudora's Directory Services.

List Management Agent.

An agent that manages distribution lists on behalf of users.


A location that stores messages for a single user.

Mailing List.

This is usually a special interest group you can join on the Internet to receive and send information. Once you belong to a mailing list, you can receive messages anyone sends to this list. If you send e-mail to the mailing list, every member of the list receives your message.

Message Application Program Interface (MAPI).

Eudoraís MAPI support allows you to quickly attach documents to e-mail messages directly from the application where you created the document. Without MAPI, you would have to save the document, remember what folder the document is in, switch to Eudora, and then remember to manually attach the document to the outgoing message.

Message store.

A collection of mailboxes.

Multi-Purpose Internet Mail Extensions (MIME).

The is an attachment decoding method best used for recipients with MIME-compliant e-mail readers, regardless of what operating system they are using. MIME is 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.


A group of connected computers that can communicate with one another. Networks enable computers to share files and resources and exchange messages.


In Eudora, a nickname is entered instead of an e-mail address. For example, in the Address Book where nicknames are set up, you can enter the nickname TERRY for When you write a message, you can enter TERRY in the To field instead of Terry's entire e-mail address. Nicknames are also called aliases.


This is an alternate e-mail account. In Eudora, you can access mail from several e-mail accounts at the same time. However, you must set up each account separately using Eudora's personality functions.


Ph (Phone book) is a protocol providing 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 Post Office Protocol 3 is a protocol that provides a simple, standardized way for users to access mailboxes and download messages to their computers. POP3 is also called the Incoming server.


A special type of user responsible for maintaining the mail delivery system for a particular group of computers. A postmaster is responsible for following up on queries from users and other postmasters. Internet standards require that the postmaster account be valid at every domain.


Windows NT Remote Access Service. This Windows 95 and NT service, when configured correctly, allows your computer to connect to your ISP via a modem. You set this up in Dial-Up Networking.


This means that incoming messages can be sent to a new recipient "by way of" you, maintaining the original sender's address in the From field.

Request for Comments (RFC).

In the Internet community, RFCs are a numbered sequence of documents generally describing protocols for Internet communication. An Internet standard protocol is also given a STD number in addition to an RFC number. Only RFCs with a STD number are standards of the IETF. Some RFCs are historical or experimental and are not standards. Others have not yet reached standard status. Still others provide documentation about the Internet itself.


This is one of many authentication systems Eudora uses. Use RPA if CompuServe is your ISP.


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.

Shared folder.

This is a folder that allows multiple users to receive mail in the same directory. Because all members of a shared folder can access messages in the shared folder, it is not necessary to duplicate the same message for multiple users. Only IMAP clients such as Eudora can access shared folders.


A signature is a few lines of text automatically added to the end of an outgoing message when it is sent. A signature can be whatever you want, but it is mostly used to give contact information (telephone, address, etc.). You only use one signature at a time in a message.

Simple Mail Transfer Protocol (SMTP).

SMTP is a protocol widely implemented on the Internet for exchanging e-mail messages. SMTP is also called an Outgoing server.


Stationery files are templates you create for outgoing messages, for example, a generic response when you are on vacation.

Table of Contents (TOC).

The TOC in Eudora is the list of messages and their data displayed in each mailbox or folder.

Transmission Control Protocol/Internet Protocol (TCP/IP).

TCP/IP is a set of protocols for computer network communication. The protocols provide conventions for connecting networks and routing traffic between them. It supports local area networks as well as interconnections between local area networks. TCP/IP protocols are described in IETF RFCs and in numerous reference works.

UNIX to UNIX Copy Protocol (UUCP).

UUCP is a UNIX e-mail protocol.


This is an attachment decoding method best used for recipients using PC or UNIX systems that are not MIME-compliant.


A character string by which users are known, for example ldempster. Username is also called Login name.


Winsock is a connection method. There are two methods of making Winsock calls using TCP/IP stacks: blocking and asynchronous.

World Wide Web.

Also known as the Web, the World Wide Web is a graphical interface to Internet resources. Web refers to the set of hypermedia pages accessible via the Internet.
