message-driven bean - permalink - collapse

All > Technology > Programming > Java

An enterprise bean that is an asynchronous message consumer. A message-driven bean has no state for a specific client, but its instance variables can contain state across the handling of client messages, including an open database connection and an object reference to an EJB object. A client accesses a message-driven bean by sending messages to the destination for which the bean is a message listener.

message element - permalink - collapse

All > Technology > Telecommunications

1. In e-mail, a specified portion of a message (e.g., the header, the body). [ANSDIT] 2. In cryptography, a predefined meaning or data representation within a message. [After X9.19]

message envelope - permalink - collapse

All > Technology > E-mail > Microsoft Email > Microsoft Exchange > Microsoft Exchange 2007

The information contained in an e-mail message that is required to send and deliver a message between messaging servers by using SMTP protocol commands. Defined in RFC 2821, the message envelope contains the sender e-mail address and the recipient e-mail address information used in MAIL FROM: and RCPT TO: as the message is routed from server to server for delivery. Recipients never see the message envelope, because it is not part of the message content, and it is discarded when the message reaches its destination. The X.400 messaging standard equivalent to the message envelope is called the "P1 header." The message envelope is often referred to as the "P1 header." [Exchange 2007]

message format - permalink - collapse

A predetermined or prescribed spatial or time-sequential arrangement of the parts of a message that is recorded in or on a data storage medium. Note: Messages prepared for electrical transmission are usually composed on a printed blank form with spaces for each part of the message and for administrative entries.

All > Technology > E-mail > Microsoft Email > Microsoft Exchange > Microsoft Exchange 2007

A term used to collectively describe all the header fields in an e-mail message. Header fields are part of the message content. Some header fields are required, while others are optional. Some header fields are created by user input, such as To:, Cc:, and Subject:. Other header fields are added by messaging servers that are involved in the routing of the message, such as Message-ID: and Received:. Still other header fields may be added by messaging applications, such as anti-spam and antivirus applications. The X.400 messaging standard equivalent to the message header is called the "P2 header." Defined in RFC 2822, the message header is often referred to as the "P2 header." [Exchange 2007]

message heading - permalink - collapse

All > Technology > Telecommunications

In radio communications, the message part or parts that (a) precede the text, i.e., the message body, in time or space according to established conventions and (b) may include several data items, such as address groups, routing indicators, action addressee designators, information addressee designators, exempted addressee designators, prosigns, prowords, clear indicators, date-time groups, originator designators, special instructions, and protocol symbols. Note: Several message heading data items may be combined into a message preamble. [From Weik '89]

message indicator - permalink - collapse

All > Technology > Telecommunications

[A] sequence of bits transmitted over a communications system for synchronizing crypto-equipment. Some off-line cryptosystems, such as the [. . .] one-time pad systems, employ message indicators to establish decryption starting points. [INFOSEC-99]

message-only journaling - permalink - collapse

All > Technology > E-mail > Microsoft Email > Microsoft Exchange > Microsoft Exchange 2003

message-only journaling sends a copy of a message to the journaling mailbox every time a user in a journal-enabled mailbox database sends or receives a message. This is not suitable for most regulations that require journaling because of compliance.
Microsoft - Cite This Source - This Definition
Message-only journaling creates a copy of all messages and the corresponding P2 message header data to and from users on a mailbox database and sends the message copy to a specified mailbox. The P2 message header contains only the message recipient data that the sender declared to the recipients. If an external message is received from the Internet, Exchange journals the P1 message headers. The P1 message header is the address information that is used by message transfer agents (MTAs) to route mail. By default, when message-only journaling is enabled, Exchange does not account for blind carbon copy (Bcc) recipients, recipients from transport forwarding rules, or recipients from distribution group expansions.

message part - permalink - collapse

All > Technology > Telecommunications

In radio communications, one of the three major subdivisions of a message, namely the heading, the text, or the ending. Note: Each message part may have separate components and each component may have elements and contents. 2. In cryptosystems, text that results from the division of a long message into several shorter messages of different lengths as a transmission security measure. Note: Message parts are usually prepared in such a manner as to appear unrelated externally. Statements that identify the parts for assembly at reception are encrypted in the texts. [From Weik '89]

message passing - permalink - collapse

All > Technology > Programming > Java

We characterize object interactions as message passing. A client object sends a message to a server object by invoking a method from the server's class. Arguments may be passed with the message, and a result returned by the server.
