BTW - Jake when I mean old - I messed up on the P4 thing (fat fingered the key) I only wish it was a P4 machine. Cut that in half - LOL. Quad PII 400. The machine is slated for a fiery death, but right now it's what we have, and with the number of users we have - we haven't worried about it. I saw this as a challenge to make VM work, and it has except for this one small problem. I think if I can limit the spam rules it reads, I would be headed in the right direction. As soon as I get that figured out - I want to use your videos to compile them. (How does that work on the updates). Then implement your improvements to tweak the server and make it perform as well as possible. I figure those will translate well to the new server and make it optimized the day it goes in.

My load average is bad on the VM, the physical machine looks ok. The physical machine is slated to be replaced, but not for approx 90days. It's causing duplicate emails to come in to users accounts. Spamdyke is helping a lot. I have killed RBLS in qmail and Spamassassin, no sense in checking them twice. I have disabled autolearn and am not using the Bayes database in Spamassassin. I am trying to optimize simscan, since I see scan times that are pretty bad - the first one I looked at was 25 seconds. I turned off clam by editing simcontrol to :clam=no. I am trying to think of any other things I can do to help out this server in the interim. I found a script that says it does the following things that make a lot of sense to me: I'm curious what your load metrics are. I've worked on 5-6 virtual QMTs in the last couple weeks, and everything seems to fall down around the 500 user mark (or equivalent load). This has been on ESX, Xen, and ESXi. We had some discussion on this on the devel list, since this is a little concerning. I have bare metal machines that have 2200+ users that run without any problem, and on "low-end" hardware (P4 2.4Ghz, 2G RAM). Also curious to see if you get the duplicates in webmail as well as lookOut. I suspect you get them in lookOut but do not see them in webmail.... If that's the case you can toss out any ideas that spam/virus/simscan are causing your problems.
