POP3 server A server that provides access to a single Inbox. Compare IMAP server.
proxy server A server that works as a barrier between an internal network (intranet) and the Internet. Proxy servers can work with firewalls, which help keep other people on the Internet from gaining access to confidential information on the intranet. A proxy server also allows the caching of Web pages for quicker retrieval.
