Is the expired time configurable? I used to use OpenBSD's spamd (for greylisting). I recall its logic being that when IP was whitelisted, it remained on the whitelist for X time since its last connection to the host (35 days was the default I believe). In other words a system that connects to my mail server a lot would remain on the whitelist essentially indefinitely. Systems that only connect to my mail server every 45 days would have to go through the whitelist process every time. I think 35 days was selected for those once a month systems that send out reminders. I'd like to achieve this same behavior with postscreen, but alas looks like not possible. :( Thank you, Chad
