While I don't know enough to evaluate the risks, this is a common request. It has something to do with (I would guess) enumerating the hosts in your network. It's a common question, for instance, on the Postfix list, and there is a simple way to do it with Postfix (and I presume sendmail as well, though I don't use that MTA.) My *first* question, however, would by "why does your Exchange server talk to the Internet"? I would put a mail gateway between your Exchange server and the Internet to limit the amount of spam and viruses you get from the world. Then I would use that box as a smarthost for your Exchange server, and let the MTA on the smarthost take care of that problem for you. Kurt On 5/30/07, Danux <danuxx () gmail com> wrote:
Hi experts!!! I dont know if it is a problem from Exchange but i thing so, let me explain... When i send a message from my local area to yahoo, the local ip address of my local mail box server is shown in Internet, i would like to know if there is a way to hide the local ip address. My client has Exchange Server SMTPSVC (6.0.3790.1830)
