Many subscribers have been reporting duplicate messages in the last few days from a couple of qmail servers I manage that send out a daily newsletter with a few hundred thousand subscribers. Yet the logs only show one message delivered to any of those people. But usually several deferrals. I figure my timeoutremote was set too low (60), so that it got delivered even though qmail-remote thought it timed out. So I now put it up to 600. Does that make sense, or could there be other reasons for duplicates that don't show in the logs? The servers are generally rather busy, with 2-500 remote processes and a system load of 4-6, and I think the ISP was having some bandwidth problems in the last few days. - Flemming
