Problem

I can't send email alerts from the Kaseya VSA Server because the Microsoft Default SMTP Virtual Server used by IIS fails to start when a 3rd party SMTP mail server is also installed.

Resolution

The Kaseya VSA Server uses IIS to send mail via the Default SMTP Virtual Server. Since the Kaseya VSA only sends mail, the Default SMTP Virtual Server may be set to listen for inbound mail on any unused port number. Avoiding the bind conflict on the default SMTP inbound port (25) allows the Default SMTP Virtual Server to run simultaneously with a 3rd party SMTP mail server.

To change the inbound port number used by the Default SMTP Virtual Server on Windows 2000:



  1. From your
  2. Start menu, select Programs -> AdministrativeTools -> InternetServicesManager.


  3. Expand the Internet services list by clicking the plus sign next to your server machine's name.


  4. Right mouse click on the
  5. Default SMTP Virtual Server and select the Properties menu item.


  6. On the
  7. General tab, click the Advanced... button.


  8. Select the entry with the IP Address of
  9. (All Unassigned) and TCP Port 25, which is the default inbound SMTP port.


  10. Click the
  11. Edit... button.


  12. Change the TCP port number from 25 to any unused port number, e.g. 4125.


  13. Click OK to close the
  14. Identification dialog box.


  15. Click OK to close the
  16. Advanced dialog box.


  17. Click OK to close the
  18. Properties dialog box.


  19. Right mouse click on the
  20. Default SMTP Virtual Server and select the Start menu item to restart it.

To change the inbound port number used by the Default SMTP Site on Windows NT 4.0:



  1. From your
  2. Start menu, select Programs-> WindowsNT4.0OptionPack-> MicrosoftInternetInformationServer-> InternetServicesManager


  3. Expand the
  4. Internet Information Server list by clicking the plus sign.


  5. Expand the Internet services list by clicking the plus sign next to your server machine's name.


  6. Right mouse click on the
  7. Default SMTP Site and select the Properties menu item.


  8. On the
  9. SMTP Site tab, change the Incoming Connections TCP port from 25 to any unused port number, e.g. 4125.


  10. Click OK to close the
  11. Default SMTP Site Properties dialog box.


  12. Right mouse click on the
  13. Default SMTP Site and select the Start menu item to restart it.
