This is one of the most common but sillyexamples; at work I have heard numerous times that people have tried clicking the "email this posting" on Craig's List. It never works if the from address is one of the internal addresses as well as the to address since the Exchange server seems to know that it isn't actually from that sender. If you use an external email address from the Exchange server in the from line it will go through just fine. There doesn't seem to be any error message or message in the queue... How do I change this? Is this a permissions problem, a receive connector setting, etc? Thank you!
