!This solution came from Microsoft's Exchange group:
!
!In earlier versions of Windows 2000, access to the local
!SMTP server was automatically open to any computer that
!tried to use it. In code, you did not need to specify
!the SMTP server, and it would default to the local
!machine and work.
!
!Later in Win 2k, and in XP, 2003, etc, this was
!tightened - you have to specifically give access to the
!smtp server. In IIS, you go to the Properties of the
!default smtp server, Access, Relay, and Add the local
!computer IP address or name to the list.
!
!And, in code, you must specify the smtpserver property.
!
!It works, but re-opens the possibility that some
!unauthorized outsider might use your machine to relay
!messages.
