请教下Exchange2013的接收连接器 [复制链接]

请教下请教下Exchange2013有5个接收连接器
在HUB上面的两个是否用于传递邮件的？
而在Mailbox上面的两个的作用是什么？为什么端口是25，难道是通过这两个吗？
最后一个Outlook Proxy Frontend是什么作用

谢谢各位解答哈！

Default <server name>   Accepts connections from Mailbox servers running the Transport service and from Edge servers.

Client Proxy <server name>   Accepts connections from front-end servers. Typically, messages are sent to a front-end server over SMTP.

Default FrontEnd <server name>   Accepts connections from SMTP senders over port 25. This is the common messaging entry point into your organization.

Outbound Proxy Frontend <server name>   Accepts messages from a Send Connector on a back-end server, with front-end proxy enabled.

Client Frontend <server name>   Accepts secure connections, with Transport Layer Security (TLS) applied.
