NoSPAMProxy - Version 3.0 NoSPAMProxy blocks the SPAM before it reaches your smtp Server. It acts as a SMTP Proxy Server and does NOT require any local SMTP Servers installed. It scans the SMTP Stream and sends a 550 as soon it classifies the STREAM as SPAM. No flooded Badmails and Queues any more. You bounce the SPAM Problem back to the origin and you save bandwith and money. Its completly plugin based and the Interfaces are documented so that everybody can add his own modules.
