We keep making it on several blacklists and I am trying to narrow down the problem. Our firewall only allows outbound smtp from our exchange, our exchange allows a few dozen addresses to relay, printers, servers and the such.
I suspect we are getting reported because our marketing department is aggressive and probably not complying with the Can-Spam act.
Before I go marching in and point my finger I would like to make sure I have checked all other possibilities. I want to make sure that its not one of the servers or some other rogue machine that someone assigned an IP address to that is in my allowed relay range.
