This simple mail (SMTP/POP3) proxy allows multiple computers on your network to share Internet access. It distributes e-mail for the entire network via a single Internet mail connection, saving the expense of a dedicated mail server.
This program is designed to perform one function and to do it well. Once configured (with the provided GUI), it works in the background passing e-mail messages efficiently and without delays. Implemented as a Windows service for stability and unattended operation, it requires Windows NT/2000/XP/2003. It will not monopolize your computer resources--there is no need to run it on a dedicated computer. Complementing a Web proxy and a firewall, the Mail Proxy is an ideal solution for security-minded small network users who use an external mail server.
Note: To run the program you will need a free trial registration key from developer Web site.
