Well, a email server stays a email server. So it will re-send the email 
regardless. Thus the motivation for greylisting it seems dubious at first.

If however coupled with a lifetime like the autowhitelist, which was my 
original intention, that would make the best example of reducing the 
impact of grey listing in the enterprise. It would still however achieve 
very good results.

Take my exmaple, apply a 10 day auto whitelist and suddenly it covers 
95% of whitelisting all business communications. In a considerably sized 
company this reduces administration a lot without reducing the grey 
listing benefits.
