How Well are Your Servers Handling MyDoom?

whosyourgeekdaddy asks: "A co-worker was showing me some of the usage stats for a clients exchange server: its averaging 630 users, and 300,000 emails per day, for the last 4 days. This made me want to ask how heavy is the workload for your 'average' Exchange server? Is this typical? MyDoom has upped the usage some, but not a lot. This client is a real estate company, so e-mail is frequently used." Of course, Exchange servers aren't the only ones feeling MyDoom. What kind of statistics have you been seeing from MyDoom, both as a user and as an administrator?
