概要

本文介绍了 multipart/report Internet 邮件格式内容类型。

更多信息

multipart/report 内容类型是为了返回包含可选邮件的投递状态通知而定义的。Exchange 2000 为许多报告类型（包括未送达报告 (NDR)、送达回执、已读回执、延迟通知、中继通知和未阅读通知）使用内容类型：multipart/report。

NDR

在 Exchange 2000 中，NDR 可能会将原始邮件作为 message/rfc822 内容类型附件嵌入到报告中，原因是 RET 参数被设置为 FULL（例如，RET=FULL）。Exchange 2000 NDR 看上去类似于以下示例：

Your message did not reach some or all of the intended recipients.Subject:	test message Sent:	12/15/2002 3:09 PMThe following recipient(s) could not be reached:user@example.com on 12/15/2002 3:09 PM The e-mail account does not exist at the organization this message was sent to.Check the e-mail address, or contact the recipient directly to find out the correct address.

注意：您可以通过编辑以下注册表子项中的 MaxDsnSize 值来限制 Exchange 2000 中的投递状态通知的大小：

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\SMTPSVC\Queuing

数值名称：MaxDSNSize
数值类型：REG_DWORD
数值数据：<以字节为单位的数值>

注意：邮件被返回的原因可能有许多种。报告的结尾会记录三位数的 NDR 代码。

下面的示例是 NDR 中的 MIME 标题：

MIME-Version:1.0 Content-Type:multipart/report; report-type=delivery-status; boundary="----_=_NextPart_001_01C21F9D.448286CC" Subject:Undeliverable:RE:--reply at 2:46pm content-class:urn:content-classes:dsn To:user@example.com Return-Path:------_=_NextPart_001_01C21F9D.448286CC Content-Type:message/delivery-status Content-Transfer-Encoding:7bit------_=_NextPart_001_01C21F9D.448286CC Content-Type:message/rfc822 Content-Transfer-Encoding:7bit

未阅读通知

如果启用了“请在阅读此邮件后给出‘已读’回执”跟踪选项，并且未曾阅读邮件就将其删除或清除，则会向邮件发件人发送一个未阅读通知。该报告通常以 Charset 7 位或 UTF 7 位的格式生成。下面的示例是一个未阅读通知：

Your messageTo:	user@example.com Subject:	test message Sent:	12/17/2002 9:02 AMwas deleted without being read on 12/17/2002 9:04 AM.

下面的示例是一个未阅读通知的 MIME 标题：

Subject:Not read:test message Date:Tue, 17 Dec 2002 09:11:08 -0800 Message-ID: X-MS-Has-Attach:MIME-Version:1.0 Content-Type:multipart/report; report-type=disposition-notification; boundary="----_=_NextPart_001_01C2A5EF.4AB815A0" X-MS-TNEF-Correlator:Thread-Topic:NRR Thread-Index:AcKl6qHrWqeamqhrQomyrF7S1Hw6dQABKjNR From:"Contact"  content-class:urn:content-classes:mdn X-MimeOLE:Produced By Microsoft Exchange V6.0.6249.0 To:"User"  Return-Path:contact@domain.com ------_=_NextPart_001_01C2A5EF.4AB815A0 Content-Type:text/plain; charset="iso-8859-1" Content-Transfer-Encoding:quoted-printable------_=_NextPart_001_01C2A5EF.4AB815A0 Content-Type:message/disposition-notification Content-Transfer-Encoding:7bit------_=_NextPart_001_01C2A5EF.4AB815A0--

送达回执

当邮件到达目标邮件传输代理 (MTA) 或 SMTP 网关时，会将一个送达回执发送给发件人。发件人可通过通信客户端将 Return Receipt To 或 Transport-Neutral Encapsulation Format (TNEF) 等效属性 PR_ORIGINATOR_DELIVERY_REPORT_REQUESTED 标记为 TRUE，以便请求送达回执。Exchange 2000 传送程序随后会通过在 SMTP RCPT TO 命令中指定 NOTIFY 参数来传送该请求。例如：

RCPT TO: NOTIFY=SUCCESS,DELAY,FAILURE

下面的示例是一个送达回执：

Your messageTo:	User; user@example.com Subject:	test message Sent:	12/17/2002 8:53 AMwas delivered to the following recipient(s):User on 12/17/2002 8:53 AM

下面的示例是一个送达回执的 MIME 标题：

已读回执

如果在邮件中标记了已读回执请求，则会将一个已读回执发送给邮件发件人。发件人可将邮件中的 Disposition-Notification-To 标题设置为发件人或 TNEF 等效属性 PR_READ_RECEIPT_REQUESTED，以便请求已读回执。下面的示例是一个已读回执：

Your messageTo:	 user@example.com Subject:was read on 12/17/2002 9:58 AM.

下面的示例是一个已读回执的 MIME 标题：

中继投递状态通知

下面的示例是一个中继投递状态通知：

This is an automatically generated Delivery Status Notification.Your message has been successfully relayed to the following recipients, but the requested delivery status notifications may not be generated by the destination.user@example.com

下面的示例是一个中继投递状态通知的 MIME 标题：

延迟通知

延迟通知是为无法及时发送的邮件生成的。发送该通知的依据是在 SMTP 虚拟服务器中配置的延迟通知时间间隔。如果传送程序通过使用 RCPT TO: NOTIFY=FAILURE,DELAY 参数从目标服务器请求延迟通知，那么当目标服务器没有及时地将邮件投递给收件人时，会返回一个延迟通知。下面的示例是一个延迟通知的 MIME 标题：
