Greetings everyone,
First, my apologies for posting a 2003 question in a 2013 forum, but the categories provided are 2013-only.
I have a standalone Windows 2008 R2 server with SMTP services and a custom app that generates email. I would like to create a domain entry on the SMTP service so messages that are destined for corporate recipients get sent from the DMZ directly to the corporate Exchange 2003 server. The Exchange server seems to be refusing connections from the standalone server even if I add its IP to the relay list; I don't get an error, the connection seems to timeout. Does anyone know how would I go about getting this working with some security?
Thanks in advance for your help,
