I would recommend against using any code in a filter without first
thoroughly understanding what it does.  That's why I have some concerns
about using the Wiki code examples.

I cannot in good conscience use the frukt.org example filter without
first reading through its 13000+ lines of code.  That's why I'm looking
for feedback on what other greylisting solutions people are using.  It
looks like I may wind up rolling my own.

Thanks for the warning; I'll watch out for this.
