A few ways I can think of: 1. On the same page where one can put in allowed IP addresses you can add "only clients that authenticate." This, however, would require any POP/IMAP clients using these servers to have to change their settings. 2. If it is a static set of addresses that are otherwise external to your org add the domain(s) of those addresses to your routing tab as <inbound> and have CRs that reroute to the address. 3. If the external machines have IPs that all reside in the same subnet, one that you do not control, have the person who controls that subnet (who would most likely by your ISP and who would likely have an SMTP server) if they can route through his box.
I suppose I could come up with some more solutions if I knew the details of what these boxes are doing, who they are sending to, etc. -----Original Message----- From: Jerry J.

Currently have our exchange server locked down so that no one can route mail from outside the internal network. Now we are setting up remote monitoring PC's that are using the internet to send alerts. But obviously that will not work since they are outside the internal network. Inputting IP info for each machine is not desired as there are over 300 machines that will be doing this and their addresses may change. Looking for a means that these computers can authenticate to the server. This is something that can be inserted into the code of the software sending alerts. But I am not seeing a sure fire way to accomplish this. So to sum it up, exchange server is locked down so no system outside the internal network can route mail. Need to find a way that certain systems that are outside the internal network can route mail thru our server using some sort or authentication that is hard coded into our software. Or any other means that anyone can think of.
