While Switching the SharePoint environment to Windows Server 2008, you may encounter a problem: you may need to send and receive emails without using an Exchange Server. An there si no
POP3 available OOTB in 2008. Microsoft has stopped shipping this product with the 2008 version, so the POP service had only been around for only one version of Windows Server. The first thought may be that the POP3 was not necesary as there are better options available for processing emails.
Now a POP3 server is something that some people need in order to be able to keep VPC lightweight (without Exchange or similar products)), and still be able to test mail sending (like alerts) locally.
