Bassline WinPopUp

Without the need for dedicated server and address-book setup, send and receive messages in your office by browsing users displayed by computer, user, or workgroup. This program lets you send instant messages and e-mails to multiple recipients simultaneously. One message can be up to 100,000 bytes and is secured by an advanced encryption algorithm. With minimal configuration, it can be sent to an IP or e-mail address. A programmable Smart Message saves your work with a global hot key and with clipboard support. Also, URL recognition, file logging, and sounds for "save" and "alert" are supported. Incoming messages can be autoreplied to, filtered, or redirected to another machine or e-mail address. With command-line messaging, e-mails can be generated by your program and script. The program is fully compatible with Microsoft WinPopup, Net Send, Messenger Service, and LinPopUp (Linux).

Version 5.27g supports the management of unread messages.
