Yep. Greylisting works. The only thing is you have to keep watch for
the few large ISPs and companies that have broken smtp services. There
is a good whitelist of known non-spam servers with broken services on
greylisting.org. I have to add about 1 IP or /24 every month or two as
I encounter someone with broken servers I have to communicate with.
