This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. Specifically, this memo extends the basic Network Services Monitoring MIB [8] to allow monitoring of Message Transfer Agents (MTAs). It may also be used to monitor MTA components within gateways.
此备忘录定义了管理信息库（MIB）的一部分，用于Internet社区中的网络管理协议。具体而言，此备忘录扩展了基本网络服务监控MIB[8]，以允许监控消息传输代理（MTA）。它还可用于监视网关内的MTA组件。

The SNMPv2 Network Management Framework consists of seven major components. They are:
SNMPv2网络管理框架由七个主要组件组成。他们是：
o RFC 1902 [1] which defines the SMI, the mechanisms used for describing and naming objects for the purpose of management.
o RFC 1902[1]定义了SMI，即用于描述和命名对象以进行管理的机制。
o RFC 1903 [2] defines textual conventions for SNMPv2.
o RFC 1903[2]定义了SNMPv2的文本约定。
o RFC 1904 [3] defines conformance statements for SNMPv2.
o RFC 1904[3]定义了SNMPv2的一致性声明。
o RFC 1905 [4] defines transport mappings for SNMPv2.
o RFC 1905[4]定义了SNMPv2的传输映射。
o RFC 1906 [5] defines the protocol operations used for network access to managed objects.
o RFC 1906[5]定义了用于对受管对象进行网络访问的协议操作。
o RFC 1907 [6] defines the Management Information Base for SNMPv2.
o RFC 1907[6]定义了SNMPv2的管理信息库。
o RFC 1908 [7] specifies coexistance between SNMP and SNMPv2.
o RFC 1908[7]规定了SNMP和SNMPv2之间的共存性。
The Framework permits new objects to be defined for the purpose of experimentation and evaluation.
该框架允许为实验和评估目的定义新对象。
Managed objects are accessed via a virtual information store, termed the Management Information Base or MIB. Objects in the MIB are defined using the subset of Abstract Syntax Notation One (ASN.1) defined in the SMI. In particular, each object type is named by an OBJECT IDENTIFIER, an administratively assigned name. The object type together with an object instance serves to uniquely identify a specific instantiation of the object. For human convenience, we often use a textual string, termed the descriptor, to refer to the object type.
托管对象通过虚拟信息存储（称为管理信息库或MIB）进行访问。MIB中的对象是使用SMI中定义的抽象语法表示法1（ASN.1）的子集定义的。特别是，每个对象类型都由一个对象标识符命名，这是一个管理分配的名称。对象类型与对象实例一起用于唯一标识对象的特定实例化。为了方便起见，我们经常使用一个称为描述符的文本字符串来引用对象类型。
A general model of message flow inside an MTA has to be presented before a MIB can be described. Generally speaking, message flow is modelled as occuring in four steps:
在描述MIB之前，必须提供MTA内消息流的通用模型。一般来说，消息流被建模为分为四个步骤：
(1) Messages are received by the MTA from User Agents, Message Stores, other MTAs, and gateways.
(1) MTA从用户代理、邮件存储、其他MTA和网关接收邮件。
(2) The "next hop" for the each message is determined. This is simply the destination the message is to be transmitted to; it may or may not be the final destination of the message.
(2) 确定每条消息的“下一跳”。这只是消息要传输到的目的地；它可能是也可能不是消息的最终目的地。
Multiple "next hops" may exist for a single message (as a result of either having multiple recipients or distribution list expansion); this may make it necessary to duplicate messages.
单个邮件可能存在多个“下一个跃点”（由于具有多个收件人或通讯组列表扩展）；这可能需要复制消息。
(3) If necessary messages are converted into the format that's appropriate for the next hop. Conversion operations may be successful or unsuccessful.
(3) 如有必要，将消息转换为适合下一跳的格式。转换操作可能成功，也可能不成功。
(4) Messages are transmitted to the appropriate destination, which may be a User Agent, Message Store, another MTA, or gateway.
(4) 消息将被传输到适当的目标，该目标可以是用户代理、消息存储、其他MTA或网关。
Storage of messages in the MTA occurs at some point during this process. However, it is important to note that storage may occur at different and possibly even multiple points during this process. For example, some MTAs expand messages into multiple copies as they are received. In this case (1), (2), and (3) may all occur prior to storage. Other MTAs store messages precisely as they are received and perform all expansions and conversions during retransmission processing. So here only (1) occurs prior to storage. This leads to situations where, in general, a measurement of messages received may not equal a measurement of messages in store, or a measurement of messages stored may not equal a measurement of messages retransmitted, or both.
在此过程中的某个时间点会在MTA中存储邮件。但是，需要注意的是，在此过程中，存储可能发生在不同甚至多个点。例如，一些MTA在收到邮件时将其扩展为多个副本。在这种情况下（1）、（2）和（3）都可能发生在存储之前。其他MTA在接收邮件时精确存储邮件，并在重传处理期间执行所有扩展和转换。所以这里只有（1）发生在存储之前。这会导致以下情况：通常，接收到的消息的度量可能不等于存储中的消息的度量，或者存储的消息的度量可能不等于重新传输的消息的度量，或者两者兼而有之。
If there are one or more MTAs on the host, the following MIB may be used to monitor them. Any number of the MTAs on a single host or group of hosts may be monitored. Each MTA is dealt with as a separate network service and has its own applTable entry in the Network Services Monitoring MIB.
如果主机上有一个或多个MTA，则可以使用以下MIB对其进行监视。可以监视单个主机或主机组上任意数量的MTA。每个MTA作为单独的网络服务处理，并在网络服务监控MIB中有自己的applTable条目。
The MIB described in this document covers only the portion which is specific to the monitoring of MTAs. The network service related part of the MIB is covered in a separate document [8].
本文档中描述的MIB仅涵盖特定于MTA监控的部分。MIB中与网络服务相关的部分包含在单独的文档[8]中。
This MIB defines four tables. The first of these contains per-MTA information that isn't specific to any particular part of MTA. The second breaks each MTA down into a collection of separate components called groups. Groups are described in detail in the comments embedded in the MIB below. The third table provides a means of correlating associations tracked by the network services MIB with specific groups within different MTAs. Finally, the fourth table provides a means of tracking any errors encountered during the operation of the MTA. The first two tables must be implemented to conform with this MIB; the last two are optional.
这个MIB定义了四个表。其中第一个包含每个MTA的信息，这些信息并非特定于MTA的任何特定部分。第二种方法将每个MTA分解为一个称为组的独立组件集合。以下MIB中嵌入的注释详细描述了组。第三个表提供了将网络服务MIB跟踪的关联与不同MTA中的特定组关联起来的方法。最后，第四个表提供了跟踪MTA操作过程中遇到的任何错误的方法。必须实现前两个表以符合此MIB；最后两个是可选的。

(9) A new table has been added to keep track of any errors an MTA encounters.
(9) 添加了一个新表以跟踪MTA遇到的任何错误。
This document is a work product of the Mail and Directory Management (MADMAN) Working Group of the IETF. It is based on an earlier MIB designed by S. Kille, T. Lenggenhager, D. Partain, and W. Yeong. The Electronic Mail Association's TSC committee was instrumental in providing feedback on and suggesting enhancements to RFC 1566 [11] that have led to the present document.
本文件是IETF邮件和目录管理（MADMAN）工作组的工作成果。它基于S.Kille、T.Lenggenhager、D.Partain和W.Yeong设计的早期MIB。电子邮件协会的TSC委员会有助于对RFC 1566[11]提供反馈并提出改进建议，从而形成本文件。

This MIB does not offer write access, and as such cannot be used to actively attack a system. However, this MIB does provide passive information about the existance, type, and configuration of applications on a given host that could potentially indicate some sort of vulnerability. Finally, the information MIB provides about network usage could be used to analyze network traffic patterns.
此MIB不提供写访问，因此不能用于主动攻击系统。但是，此MIB确实提供了有关给定主机上应用程序的存在、类型和配置的被动信息，这些信息可能表明存在某种漏洞。最后，MIB提供的有关网络使用情况的信息可用于分析网络流量模式。
