RSend

RSend is designed for real-time instant messaging between a large number of users on LANs and WANs. RSend is a "client-server" application based on .NET Remoting technology using TCP protocol. The program successfully works with subnets behind routers while consuming minimal system resources and network traffic. RSend allows you to send single messages and mass mailings.

In order to form mass mailings, the program provides the possibility to build lists by different criteria: by user name, by computer name, by shared (domain) or personal groups. By using asynchronous, multi-threaded data transfer mode, the average delivery time ranges from one to several seconds (depending on the number of recipients, the state of remote computers and the server platform).

RSend has additional features for convenience:

• Built-in search and filters for granular construction of message recipient lists;
• Prompt response to incoming messages;
• Generating a confirmation request for message delivery;
• Using "hotkey" functions in the program.
