邮件大小的那点事儿

24 Jan
之前的挖坑文和case文中已经描述了邮件大小限制的问题。今天重新简单的描述一下。

首先回顾一下之前的那点事儿

  • 全局设置

全局设置默认接受发送都是10MB

Get-TransportConfig

查看:Get-TransportConfig | ft MaxSendSize, MaxReceiveSize

修改:Set-TransportConfig –MaxSendSize 20MB –MaxReceiveSize 20MB

  • Receive Connector设置

接受连接器是属于服务器级别的。每个服务器上可以有多个接受连接器,彼此相互独立。Exchange默认安装的2个接受连接器,大家最好是保留,不要去删除了。如果全局设置比其设置的小,那么以全局设置为准。

查看Get-ReceiveConnector | ft name, MaxMessageSize

修改Set-ReceiveConnector “default connector” –MaxMessageSize 20MB

或者get-transportserver | Get-ReceiveConnector  | Set-ReceiveConnector | Set-ReceiveConnector  –MaxMessageSize 20MB 

  • Send Connector设置

发送连接器是一个组织级别的设置,但同样可以创建多个。如果全局设置比其设置的小,那么以全局设置为准。

查看Get-SendConnector | ft name, MaxMessageSize

修改Set-SendConnector “Send connector” –MaxMessageSize 20MB

  • 邮箱设置

默认下,Exchange 2007对用户邮箱设置时没有设置限制的。影响到他的就是之前的3个限制。只要任何一个限制低于邮件实际大小,该邮件就会发送失败。

查看Get-mailbox | ft Name, MaxSendSize, MaxReceiveSize

修改Set-Mailbox “xunyang” –MaxSendSize 10MB –MaxReceiveSize 10MB

  • 常见错误

以下列出集中常见的错误

  • 1-发送服务器发出NDR

The following recipient(s) could not be reached:

test@contoso.com on 01/15/2010 5:54 PM

This message is larger than the current system limit or the recipient’s mailbox is full. Create a shorter message body or remove attachments and try sending it again.

<xunyanit.com #5.2.3 smtp;450 5.2.3 Msg Size greater than allowed by Remote Host>

这是远端服务器不允许,需要去协调远端服务器管理员

  • 2-接受连接器发出NDR

The following recipient(s) could not be reached

test@contoso.com on 01/15/2010 5:55 PM

This message is larger than the current system limit or the recipient’s mailbox is full. Create a shorter message body or remove attachments and try sending it again.

<contoso.com #5.2.3 smtp;550 5.2.3 RESOLVER.RST.SendSizeLimit; message too large for this sender>

  • 3-用户发信后收到本地服务器NDR

Delivery has failed to these recipients or distribution lists:

administrator@xunyanit.com
This message exceeds the maximum message size allowed. Microsoft Exchange will not try to redeliver this message for you. Please make the message smaller — by removing attachments, for example — and try sending it again, or provide the following diagnostic text to your system administrator.

Diagnostic information for administrators:
Generating server: hub01.contoso.local
administrator@xunyangit.com
#550 5.2.3 RESOLVER.RST.SendSizeLimit; message too large for this sender ##

请按照字面意思去检查问题所在即可。
