Can I use the SpamBouncer on my Macintosh?
If you run Macintosh OSX (any version), you can. OSX is a variant of the Unix family called “Berkeley Standard Distribution” (BSD), with the Macintosh GUI on top. A Macintosh running OSX is therefore a Unix computer, and can run almost any Unix-based shell program. The SpamBouncer requires only Unix shell programs and runs in the Unix shell; it does not require any GUI software. But you might not want to. Installing and configuring a Unix shell program is nothing like installing and configuring a native Macintosh program. You need to be comfortable working at the Unix shell, understand compilers and how to build a program from source code, know how to create Unix accounts and configure them to send and receive email, and understand how to set up your Macintosh’s underlying Unix shell system to retrieve and process email. In addition, as far as I know you cannot configure the SpamBouncer or Procmail itself to deliver email directly to your native Macintosh email programs.
