How do you configure the smtpserver port for system.web.mail in vb.net 1.1 on Windows 2005 server?

I need to change the smtpserverport from 25 to 10045 for a client.
Using system.web.mail, developing in VS 2003 / vb.net 1.1.
Hosted on Windows server 2005.

It has always worked until I added this line:
msg.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpserverport", "10045")

... and it returns a 'Fields update failed'.

Is there a better way to set the port?

System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Runtime.InteropServices.COMException (0x800A0EA5): Fields update failed. For further information, examine the Status property of individual field objects.
