I have a couple of websites that I want to allow pages that provide .aspx pages to send email. I am using aspNetEmail dll's and this works fine as long as as I am sending 'internally' to guicorporation.com. The problem is properly setting up Exchange virtual server as a relay. I do not want the exchange server to be 'wide open' as a relay but only want the 2 sites (idcreporting.com and idc-cooper.com) to be able to send mail via exchange. Topology is:
Machine WIN2003ENT runs:
Machine WIN2003 runs:
How can I configure these is a safe manner (allow only confirmed e-mail from either of these sites) to be sent out and blocking all others. I read somewhere that I need to configure SMTP on IIS (the WIN2003ENT box) to do this but am confused as to where?!!
Any info would be appreciated....
