Now the problem is, we have to use the tranditional mbox format with dovecot, as it does not support indexed mbox format, which makes deleting messages costly. Also the long-time file locking (due to the slow operation on the dovecot side) causes our MTA (exim, by the way) holds a huge queue. That drives up the system load to mad (load average above 500 is not unusual in our case).
sorry just have to ask - does your server actually WORK at loads of 500? What kind of usage have you got?
