Um, Jon, greylisting... great!  But, I'm not so sure I'd trust it to
a random example script.  I'd very much recommend using either one
of postgrey[1] or gld[2] (grey listing daemon).  I've heard of major performance
problems with implementing greylisting in a hap-hazard way and I know both
of those daemons have worked hard to solve problems like that (and a random
script off a website almost certainly hasn't).

Cheers,
Tanner
