I was just looking at this earlier today and trying to figure out how it works. I think it goes like this:
X = Maximum SMTP Sessions/IP Frequency Y = Maximum SMTP Sessions/IP Frequency Duration Z = Maximum SMTP Sessions/IP Frequency Expiration If an IP address connects to your ASSP server, the time and originating IP address of the connection is logged and a counter is incremented. A system can only connect to your ASSP server X times within Y seconds. If a server violates this policy and connects more times than it is allowed, it must wait Z seconds before it can successfully connect again. For normal usage, a server should not connect more than X times within Y seconds. In this case, after Y seconds are up, the counters are reset. My guess is that you have a lot of mail coming from these servers so they are connecting very frequently to your mail server. As a result they are violating the policy you have set and being blocked from further connections. This could be because the mail servers are being used to send spam messages as well as send legitimate messages, or it could be because you have your timeouts and session threshold set too low. Someone tell me if I got this mixed up. I just read the code and it is a little confusing to the uninitiated.

Well, I'm finding this is coming up for two domains, yahoo.com, and sbcglobal.net, or at least from two users that email to one of our clients. What I don't understand is what is causing this to happen? Is it something my server is doing, or ???? I need to figure this out, as the emails being sent are being dropped due to LimitingIPFrequency.
