Those two do not contradict each other. PostGrey simply stores an entry with a timestamp. It doesn't record that anything is waiting, just when the last SMTP connection was made. If someone sends an email to the same person from the same server every few days they are never greylisted, and for

Sorry, you are overestimating PostGrey’s ‘inteligence’.PostGrey doesn’t care about what is waiting. It just tells the connecting server to go away and come back later. When it connects again it just does the maths and if it is more than 300 seconds it lets it through. It then updates the

There is a reporting tool that goes through your mail logs and finds the entries that have been delayed by postgrey and haven’t sucesssfully resubmitted. It isn’t 100% as it doesn’t look in rotated logs, and I can’t remember what it is called, but there was one a few years ago. Marco van Beek
