Setting Up Exchange 2003 to receive from SMTP

[IPTMarcus]

I have a customer running Exchange 2003 and is not willing to open a relay on the server to allow an application to send email through it. I can setup an SMTP Server on the local PC (Running Server 2008 where the app is running) but I am not sure how to tell Exchange 2003 to receive email from this PC.
For example I want to be able to tell Exchange 2003 to allow/receive all email coming in from 192.168.1.10 (for example)even though there is no valid reverse DNS. This would also not force the email to go out of the network and come back in.
Any suggestions would be greatly appreciated

There should be an smtp connector on the server to receive email. Set the application server to point to that as anonymous smtp and if the mail is internal only then you'll be fine. If the mails are external only, point the application server at the next hop from exchange eg a firewall. If the application server does both internal and external then they need a relay from that IP address or it won't work.
