Services → POP3 Server → General tab
This page sets the general settings for the POP3 service component in VPOP3. The POP3 service is how users collect their email from VPOP3 using a POP3 email client
The Service Name is a name you give the service for your reference. It is only used in administrative displays and logging, so the name doesn't matter. Most people leave it at the default.
The Bindings section shows the TCP/IP addresses and ports that VPOP3 is listening on. The default for the POP3 service is to listen on all available addresses, on port 110. If you have another mail server on the same computer as VPOP3, you may want to configure multiple IP addresses in Windows, and tell each of the servers to listen on a different IP address.

The Encryption option tells VPOP3 what sort of encryption should be used on POP3 connections between email clients and VPOP3. This option is only available in VPOP3 Enterprise, if an SSL certificate is available.
The three options are:
See here for the different types of encryption.
If this box is checked, then VPOP3 will not allow a plain text password. VPOP3 will either require an encrypted connection (see above), or a password encryption method such as APOP or CRAM-MD5
The Bandwidth Throttling setting lets you set bandwidth throttling options for this service. For more details, see our blog.
