NoSpamToday! for Servers
System Requirements
On the Linux/i386 operating system, NoSpamToday! for Servers runs as a daemon, and on the Windows platform as a service (requires Windows 2000/XP/2003/2008/Vista).
CPU and memory requirements depend on the desired e-mail throughput. As a rule of thumb, mail filtering requires about twice the processing power of your mail server.
You can run NoSpamToday! for Servers on the same machine as your mail server. This way, no additional hardware is needed.
