Vypress Auvis is a message client for Vypress Messenger. It allows any computer running TCP/IP on the Internet or a LAN, to receive messages from the Vypress Messenger server almost instantaneously. The client sits in the system tray, waiting for incoming messages and alerts the user by popping up or playing a sound upon receipt. Vypress Auvis can also monitor POP3 mailboxes, trigger an alert when new mail arrives, and even launch the specified mail client. Features include filtering addresses that can send messages by denying certain addresses or only allowing specific IP senders. It is a one way communication system, which means that this client can not respond to the message.
