Send mail from Windows SMTP server to Windows POP3 Service on the same machine

I've setup a Windows SMTP server and a Windows POP3 service on Windows Server 2003. Can I have the S开发者_高级运维MTP server send directly to the POP3 service without setting up a public IP address and domain? The Windows Server is a VM in it's own Workgroup (no other computers) sitting on top of a corporate network.

You should be able to use the loopback ip address (127.0.0.1) for this, or if you must use a host name then the one mapped to it in the hosts file - localhost.
