What is your mail volume? You really need a serious amount of mail for SA to bog down. As you all realized, mail volume is relative. >From what I've seen you can handle 100-200K messages per day on a single 2-3GHZ mimedefang+sa box with no problem. Then throw in greylisting if sa is slowing you down. That should work well at reducing the number of messags you need to run content-analysis on with sa. Greylisting has worked well at blocking drive by spammers from one shot ip addresses. I've used it on my production servers with never a complaint. -- --Luke CS Sysadmin, Montana State University-Bozeman
