I check the logs for the last failure, and see that at the same second two servers were trying to deliver separate messages to the same account. I'll try avoiding a bit of these parallell deliveries by changing MX to prefer one host. That might help as a workaround, but might fail next time this preferred host is too busy to process all requests.. -jf
