One quick suggestion - if you are writing your mail files to a drive that is
using something like RAID 5, then that'll hurt WRITE performance. Monitor
your disk I/O carefully - writing that many files to a RAID 5 can slow you
down. There is a couple extra I/O attempts (for parity n verification) - a
mirrored drive would work better than a RAID 5 in this case since a mirrored
drive writes faster than striped drive.
iMS should be able to handle many more emails than that - you got the cpu,
memory is fair, size of HD doesn't matter - use performance monitor to look
for disk i/o bottlenecks - and if you are using a sql database, especially
thru a lan or other ip connection, check out those to see if that's your
bottleneck.
