• MS Exchange server on a dynamic ip

If the port is blocked, your server will give the following error message "connection timed out with the server" . This is due to the fact that EDPnet blocks all the outgoing traffic via port 25 (for dynamic IPs) except to our relay server. In this case you need to set up our relay as smtp server.

Step-by-step instructions

1. Start Exchange System Manager

• From your Windows Start Menu, select:
  Start > Programs > Microsoft Exchange > System Manager

2. Select the SMTP Virtual Server

• From Microsoft Exchange Service Manager select:
  Servers > your exchange server > Protocols > SMTP > Default SMTP Virtual Server

3. Modify the SMTP Virtual Server

• Using your mouse's RIGHT BUTTON right-click Default SMTP Virtual Server. Then select Properties from the popup menu.
• Click the Delivery tab. > Advanced

The dialog determines where Exchange Server sends it Internet messages.

• In the Smart Host field enter relay.edpnet.be

• Click OK.
• Click OK to save your changes and exit the Default SMTP Virtual Server Properties dialog.
