This Server is entirely written in Java, which means that it will run on ANY system that supports Java 1.0.2 or higher.
Additional security is built-in.
J-POP can be configured to deny access to all Internet hosts except those explicitly allowed. J-POP also supports the APOP authentication mechanism so that users don't have to send their passwords over the network. Through this GUI, an adminstrator can add, delete and modify users, change configuration options on the server, and update which hosts are allowed to access the server. After making changes through the GUI, there is no need to restart the server, it detects these changes automatically. This includes RFC1939, RFC1725, RFC1460, RFC1225, and RFC1081.
