Hi Ken,

I know this probably doesn't address the root of your issue, but I have this cron job that runs daily to clean out those bogus rejects:

ACK! No no no! :) What happens if I go out of town, connect via my friends DSL, use his SMTP server, and send you mail -- but my mail server back home is down? So I loose a notification that the mail wasn't delivered. But what happens if I sent that message 5 mins before the cron job runs, and my mail server wasn't down but for 5 mins? I lost my undeliverable notification due to a strange coincidence that would be very difficult to chase down. A much better option would be to upgrade to Postfix 2.1, and use the built-in feature (bounce_queue_lifetime) that lets you limit the amount of time any undeliverable or other mailer-daemon generated message can live in the queue. You can have them automatically expire after 4 hours, 8 hours, 1 day, what ever your needs require. But please don't arbitrarily whack them at a given time. :)
