We have a 3rd party spam service that filters all e-mail from spam, viruses before sending it on to our exchange server. The 3rd party recommends that we lock down exchange to only accept e-mail from their ip addresses they have provided us with.
I just want to make sure I am putting the info in the correct space. I have see the delivery restrict tab in Exchange 2003 but am not 100% sure that's what I need. I would just like to tell Exchange "hey only accept e-mail from these 2 ip's addresses...anything else reject it.
