How to change TCP/IP port from 25 to any other value in Microsoft Exchange

To change the SMTP listening port on a server that is running Exchange 2000 or Exchange 2003 from port 25 to another port, for example, port 2500, follow these steps:

1. Start the Exchange System Manager.
2. Locate and click Servername, click Protocols, and then click SMTP.
3. Right-click the Default SMTP Virtual Server object, and then click Properties.
4. On the General tab, click the Advanced button, click the Edit button, and then set the Transmission Control Protocol (TCP) port to 2500 (or whatever new value you require).

This method sets the port that this virtual server listens to for SMTP traffic.
