It highly unlikely that you will lower the cpu usage until you figure out the details of the log files. The high cpu could be a symptom of something else. Maybe a failed dns server upstream, wrong config setup, or a million other possibilities. Look at your virus packages are they ok? Has anything changed lately? Look at Event viewer for hints. Turn on verbose logging for the smtp server in Imail.
Good Luck.

We end up with a ton of mxguard processes (even when our limit was lowered to 10, this morning), and CPU usage cranks way up and stays there. When you guys get something like this, aside from the logs, what's the first place you can look to "immediately stem the flow", aside from stopping the smtp service altogether? I tried the log analyzer, but I can't really figure out exactly what it's telling me.... I don't know if these emails are coming from an outside soure, or perhaps even from one of our own POP3 users... Just looking for a quick first-glance analysis if there is such a thing, that can help me lower the amount of CPU usage without killing the whole SMTP service, until I can dig deeper...
