976508 to be exact :-) but it's very much a useless number. Lots and lots of these are inactive. A better number is probably that we're seeing about 80 logins/second for the last hour.. (just checked now, not sure if this is the most busy hour or not).
How many servers you have? hardware?
7 backend dovecot servers (two IBM x336, three x346 and two x3550, with a 8 GB for the x336/x346 and 16GB memory memory for the x3550's). 2 frontend dovecot directors (IBM x3550).
None of these are really very busy, so we could probably reduce the number of backends a bit if we wanted. Our struggle is the number of iops we're able to get from the backend storage (IBM DS4800), mostly a problem when we have storms of incoming marketing messages in addition to the pop/imap traffic.
