As mentioned before, I set up a graylisting combo on two incoming mailservers using Postfix, MySQL and Perl (on Solaris 10). This solution runs now for 19 days and I took the time to analyze the database a little bit. Here's a plot of the number of positive graylisted entries since the beginning (X-axis represents the number of days since the beginning):
The number of new entries per day is going slowly down, as expected.
These servers deliver mail for approx 12,000 users. So at the moment every user statistically receives mail from 40 correspondents.
The two SQL databases are running fine, and every night between 2.5 and 6 million rows are deleted (inactive graylisting entries which did not become active after 48 hours):
