Over the past 24 hours, we've been experiencing what I can only describe as a "flood" of emails coming into our mail server. 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...
