exchange 2007 enable a relay of mail from a specific local IP
Im trying to setup a relay to allow a web based application on a local webserver send email through our exchange server.
Ideally I would like it to authenticate first.
It needs to be able to send as different people, so that when students reply, the replies go to the respective teacher that generated the email.
At the moment the webserver is just sending emails using its own buildin postfix, but I would like them to be going through our exchange.. Im just not sure how to go about it?
