RubyFilter

If you're in need of a Ruby email filtering program and library, then RubyFilter is definitely worth taking a look at. It's a versatile Ruby email filtering program that can act as a replacement for delivery programs like procmail, and it's also a helpful Ruby module with classes that simplify the process of filtering and delivering email.

To get started with RubyFilter, you'll need to make sure you have Ruby 1.6.* or 1.8.* installed on your system. RubyFilter has only been formally tested under Linux, but it should work just fine with any Unix setup.

To install RubyFilter, simply enter three commands while in the package directory - 'ruby install.rb config', 'ruby install.rb setup', and 'ruby install.rb install'. Depending on your system settings, you may need special permissions to execute the last line. However, if you only want to install RubyFilter to a custom location, you can manually copy the rmail subdirectory instead.

Recent updates to RubyFilter include changes to ensure compatibility with Ruby 1.8.1, and there's no longer a need to verify that a Unix mbox file is formatted correctly before appending to it. Overall, RubyFilter is a valuable tool for those who need effective email filtering capabilities combined with Ruby's programming flexibility.
