問題：

ESA是否可將SMTP流量傳送到除25以外的其他埠號？

埠25是標準SMTP埠郵件交換伺服器用於偵聽傳入電子郵件。可以將ESA配置為通過備用埠將郵件傳送到特定主機。其 smtproutes  cli中的指令是設定此指令的最簡單方式：

mail3.example.com> smtproutes

There are no routes configured.

Choose the operation you want to perform:

- NEW - Create a new route.

- IMPORT - Import new routes from a file.

[]> new

Enter the hostname for which you want to set up a permanent route.

Partial hostnames such as ".example.com" are allowed.

Use "ALL" for the default route.

[]> testexchange.example.com

Enter the destination hosts, separated by commas, which you want mail for

testexchange.ironport.com to be delivered.

Enter /dev/null by itself if you wish to discard the mail.

[]> exchange.example.com:1025

Mapping for testexchange.ironport.com to exchange.example.com:1025 created.

There are currently 1 routes configured.

Choose the operation you want to perform:

- NEW - Create a new route.

- DELETE - Remove a route.

- PRINT - Display all routes.

- IMPORT - Import new routes from a file.

- EXPORT - Export all routes to a file.

- CLEAR - Remove all routes.

在這種情況下，系統配置為通過埠1025將testexchange.example.com的郵件傳送到exchange.example.com。

您也可以通過GUI、網路 — >SMTP路由 — >新增SMTP路由並使用所需埠填寫域和目的主機，進行上述更改。完成之後，您必須提交和提交更改。

要配置ESA以使用裝置GUI通過備用埠將郵件傳送到特定主機，請選擇Network > IP Interface並修改IP介面的設定。
