It's heavy and loads machines. Greylisting is an easy and light way to block most spammers. In order to have greylisting working, you just need to find a filter which do it. Like courier-pythonfilter. Gordon Messmer published a new release 2 days ago !
http://www.dragonsdawn.net/~gordon/courier-pythonfilter/ You can use greylist or comeagin filter. I didn't test them. Some papers suggest to have a manual whitelist. In fact, there is no hard constraint on that. At worst, mail will take longer to deliver. It will always be better than a challenge response. I don't like the idea of whitelist... What if one server in this list is beginning to spam? Another suggestion: use URIBL... like zen.spamhaus.org. Your courier version is very old. Too old. Lots of improvements have been implemented since 0.53. I discovered yesterday that, since 0.59, we can modify mail contents easily :) HTH.
