SMTP server spam gateway.


Developer website: Outspring Software

Spamphibian Gateway is a unique new stand alone spam-fighting solution that works with your existing SMTP server. Included is Spamphibian Admin, an easy-to-use Mac OS X application to remotely monitor, configure and administer Spamphibian Gateway.

Spamphibian Gateway is a server-side spam stopper, which means messages caught by Spamphibian Gateway are halted at the server and do not reach the user's account. The administrator can manually create any number of IP addresses, domains, URLs, generic string, or regular expressions filters to stop unwanted mail.
