Long ago when the old AT&T existed, they used the number of times that the phone system was down and the longest duration of those gaps in servive. With ESS they were able to run for months without a service gap longer than a few hundred milliseconds. Such performance is quite unnecessary for email, but the idea of measuring service gap duration and generating statistics on that and delivery delay time is better than up-time, IMO. Uptime is of no use to a customer. The only thing he can notice are service gaps. If you can keep tham short enough, no one will care how many there are. -- Paul E Condon pecon...@mesanetworks.net -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
