I modded up my (well, the code that was posted here some time ago) greylisting code to track authenticated outbound mail as well. Coupled with a db expiry scheme which deletes singleton inbound entries (one's that have a count of 1) after two days, decrements the count of non-singleton entries every 10 days and leaves any singleton entries that have a reverse entry (whitelist) alone. It was my first perl program from scratch after having cut my teeth on mimedefang-filter (with the o'reilly book in my lap). I run it as a cron every night. I like the results. -lee
