You are certainly pushing your hardware more than we are. We are doing 2500 in and 500 out, less than 1/10th of your activity. We also have one domain with apprx 300 users, less than 1/3rd of your users. With this light load, we are seeing ~5% cpu on average with a dell server running win2k server sp4, 512MB ram, and two 700mhz Zeon processors. Honestly I don't know how different a 700mhz Zeon is from a 650mhz PIII, but I understand the Zeons to be more suited for server duty. Might be time to upgrade your equipment. :o)

I have been noticing a bit of a lag when connecting to the outgoing mail. I telnet'd directly and it took a good 90 seconds for a confirmation to ehlo. I then terminal serviced and checked my cpu usage through windows task manager and it's been up at 96-99% for the past hour or two. This looks to me like we'll need faster cpus in this machine, or should we consider a load balancing solution between two servers? Or should IMail be able to handle this load with these processors? Our current machine is: win2k sp4|imail 8.0.5 hf2 COMPAQ PROLIANT w/ dual pIII 600s | 768 ram Approx 250 virtual domains w/ avg 4 users per domain For an average weekday it appears to locally deliver 25k messages, and remotely deliver 17k messages. I'm not sure on my Monday statistics (as I've just recently started taking these), but it's significantly higher. Is there a tool that will count the users and domains for me? Also, I'd like to look into seeing what sort of network traffic is occurring on the server. Can anyone recommend a good utility for this? Will netmon take care of me in this aspect?
