Mail rejected from "dynamic address" - no deletion

[ScottF4]

I received an error notice that Email sent to me from the publishers of NeoOffice was being "rejected - looks like a dynamic address". (I'll send the complete msg privately so you can whitelist them.) The error msg said that the msg was rejected 109 times. How come my stats don't show any deletions on that address?

Thanks.

We've been under a heavy denial of service attack from a large botnet which consists almost entirely of dynamic IP addresses. To get the service back up, we had to block anything that looked like a dynamic IP address upstream from our code.

Please do send the info -- we really only need to know which machine they're trying to send from. I tried to determine it based on the neooffice.org domain, but couldn't.
