I'm currently running an exchange 2003 server.
My email is sent via an SMTP connector to my isp's smtp server. The same is done for retrieving pop3 email.
Now I want to send a message on behaf of an email address.
The email address is not a known user in my AD. Just a plain smtp email address.
I am aware how to send on behaf of an user, but that's not what I'm trying to accieve cause I'm not sending on behaf of a user, but on behaf of an email address.
How to do this ?
My outlook keeps telling that I don't have permission (but I guess that has to do with the 'send of behaf of user' setting)
