Hello all. I have an exchange 2003 server that I just updated to host some more mail domains. I changed the default send from domain and all works well with that. The problem is if I try to send using any other configured domain, I get the following: You do not have permission to send to this recipient. For assistance, contact your system administrator. I have it set to allow all authenticated users to relay and even added my whole subnet to the relay allow list and still no go. Any help would be gr8ly appreciated. --- Regards, NumbLock Et Al -------- There are only 10 kinds of people in the world. Those who understand binary and those who don't --------

hi, In my mind, you only can use the primary mail address to send mail. If you want to achieve your goal, i think you should use the send as feature. How to use send as you can see this link:http://blogs.technet.com/b/exchange/archive/2005/01/07/348596.aspx Or a third party software can help you. hope can help you thanks,CastinLu TechNet Community Support
