Our CEO seems to get a bounceback or NDR with the following as the reason
554 Spam detected
everytime he send mail when he out of the office, I.E with his Laptop. This is primarily on 3G or on his own Lan.
Our setup is server 2k3 with 2007 exchange.
We checked with the ISP and they have said its something to do with our exchange.
Has anyone got any experience with this , we are out of ideas
Thanks in advance.
